Asked in Science, Chemistry, Periodic Table What is the fourth element of the periodic table of elements? That would be all metals that aren't iron or iron alloys.

Yeah, like aluminium, zinc, copper, lead, beryllium, titanium, etc. A highly radioactive metal and weakly basic actinide. Asked in Science, Periodic Table What are some materials or things that change from solid to gas? Sublimation is where a solid turns into a gas directly without a liquid stage. Many solids are able to do this under the right temperature and pressure conditions. Common examples are mercuric chloride, iodine, and carbon dioxide. Clinistix is a commercially available product for testing for of glucose in urine.

It turns purple if glucose is present. Albustix is a commercially available product for testing for the presence protein in urine. Lithium Liwith a Mohs hardness of 0,6. The first periodic table was developed by Dmitri Mendeleev in the midth century. He wasn't the only person thinking along those lines He made the first periodic table by taking the elements he knew, and arranging them according to atomic mass.

He then discovered a pattern in his table, and left empty spaces for elements yet to be discovered. Asked in Periodic Table What color is Tellurium? A mass number is the total number of protons and neutrons found in an atom.

To find the mass number, you must know the number of neutrons in that particular isotope of the element and then add the atomic number same as the number of protons to it. When this number is definite it is called a nuclide and the symbol is written with a superscript giving the mass number and a subscript giving the atomic number number of protons placed in front of atomic symbol: Na.

It can also be written after the elements name, sodium Do not confuse this with the atomic number, which is the number of protons. Henry Moseley did a series of experiments looking at the x-ray spectra of various elements. He found that the frequencies of equivalent bands made a very simple progression that more or less corresponded to atomic weight order. The exceptions were exactly the same as the ones where Mendeleev's scheme was having difficulties. He thus arrived at a definition of atomic number, and proposed a revised periodic law where the ordering of elements was according to atomic number rather than atomic weight.

Different reactions require different solvents. Sometimes the polarity of H2O can hinder the progression of the reaction by H-bonding to the reactants. Also, sometimes a reaction requires a stronger or weaker solvent to insure that you have your reactants reacting and not a reactant with the solvent. Asked in Chemistry, Periodic Table Colored salts generallly have a cation from which section of the periodic table? Coloured salts generally have a cation which is a transition metal.

Iron, Chromium, Manganese, Vanadium and Copper all are examples of transition metals that make colourful salts. Notice that there are exceptions - particularly the period 6 main group metals like lead share some of the properties of the transition group metals and can make colourful salts - the bright yellow precipitate of lead iodide PbI is an example commonly used as demonstration of precipitation reactions.

Dobereiner became a professor at the University of Jena in Between and a number of scientists continued work on these relationships and the "Law of Triads".

The ionization energies of elements increase as you across the same period here, the third periodaccording to the general trend. This is because the number of protons increasepulling back the valence electrons further - and hence making it harder to separate an electron. However, there are exceptions! For example, the ionization energy of phosphorus is higher than that of sulfur. This is due to the fact that phosphorus has half-filled 3p-orbitals, giving the configuration some extra stability.

The first ionization energies of sodium, phosphorus, sulfur and chlorine are, and kilojoules per mole respectively.

Concerning the atomic radii, which of the following is true? The period number is an indication of how many electron shells an element possesses. Since the definition of an electron shell and an electron orbital is a 3D space where there is a high probability of finding an electron, more electron shells mean a larger atomic radius.

Carbon's atomic number is 6, nitrogen's is 7, and oxygen's is 8. Boron is the fifth element, and it is reactive, but not at a critical condition. This element is interesting, because it is very rare to find it in a state in which it is pure boron.This KS3 Science quiz asks questions about atoms and elements.

Atoms are part of elements and elements are listed in the periodic table. Did you know that atoms are so small, one million atoms in a row is roughly equal to the thickness of a piece of paper?

questions about the periodic table and answers

Imagine that! There were two accepted systems of numbering the periodic table, one of which called the noble gases group VIIIA, often changed informally to group 8 most commonly used in the USA and the other that called it group 0 most commonly used in Europe. The naming of anything in chemistry now is governed by a single organisation IUPAC International Union of Pure and Applied Chemistry and they have simplified the group numbering, the noble gases have now become group Groups are also often referred to by the name of the first element in the group - the noble gases could also be called the helium group.

Other than groups 1 and 2, all of the other group numbers have changed. For example the halogens are no longer officially group 7, they are group At the moment, many school text books still refer to the groups by their old numbers and names though some schools maybe even yours may already have changed.

Are these elements metals or nonmetals? How many valence electrons do they have? Name a property that these two elements share. Barium and magnesium are both found in the same group in the periodic table.

What is the group called and what number is it? Also name two properties that they would be expected to share. Ionization energy is the energy it takes to remove an electron from an atom.

Ionization energy increases across a period because as the number of protons increases the atomic radius decreases. It is harder to take an electron off a small atom, so ionization energy increases. Ionization energy also decreases down a group for the same reason. Electron affinity is the amount of energy absorbed when an electron is added to an atom. Electron affinity increases from left to right across the periodic table.

This is caused by the decrease in atomic radius. Moving from left to right across a period, atoms become smaller and smaller as the atomic number increases. This causes the electron to move closer to the nucleus, thus increasing the electron affinity. Electron affinity decreases as we proceed down a group for the same reason. An atomic radius is total distance from an atom's nucleus to the outermost electron orbital.

Atomic radii become smaller as you go from left to right across a period because the charge in the atom's nucleus becomes larger increases Z eff. This increased charge pulls the electrons in closer. Atomic radii become larger as you go down a group because the outermost electrons are located in orbitals located further away from the nucleus the principle quantum number, n, has increased. Electronegativity is a measure of the attraction an atom has for electrons.

As you move to the right across a period of elements, electronegativity increases. Atoms can either gain electrons or lose electrons. When the valence shell of an atom is less than half full like on the left hand side of the periodic tableit's easier to lose an electron. When the valence shell of an atom is more than half full like on the right side of the periodic tableit's easier to gain an electron.

As you move down a group, electronegativity decreases. As we navigate down a group the atoms get bigger and bigger with more and more electrons.

Periodic Table Trivia Questions & Answers

This means the outermost electrons get further and further away from the positively charged nucleus. Electronegativity decreases for this reason.

Cl and Br are halogen elements. They are non-metals located in group seven. Noble gases are inert because they have the most stable electron configuration.

Their valence shells are completely filled so they have no need or desire to lose or gain electrons. Ba and Mg are alkaline earth metals located in group two.You may remember the Periodic Table of the Elements as a dreary chart on your classroom wall.
