But the logic of the periodic table also relies upon the number and organisation of electrons in an atom. Let’s take chlorine as an example. It is positioned in group 7 of the periodic table ...

The chlorine atom has a higher electronegativity than the hydrogen ... which is very practical and accurately reproduces both molecules' energies and chemical reactions. The periodic table's most ...

The periodic table is a way of arranging elements according ... a sodium atom combining with one chlorine atom, we get sodium chloride or salt. So that’s an example of a compound.

chlorine is less reactive than fluorine because the outer electrons in a chlorine atom are further from the nucleus than the outer electrons in a fluorine atom. It is harder for a chlorine atom to ...

The reaction releases a lot of heat as the ionic compound sodium chloride is formed. A sodium and chlorine atom are near each other. An electron from each atom feels the attraction from the other atom ...
