Fluorine, Chlorine, Bromine, IodineIf you write the electronic structure to start, F = 2,7, Cl = 2, 8, 7, Br = 2, 8, 8, 7, I = 2, 8, 8, 8, 7. This shows that they all have 7 outer electrons so we can tell...

The mutual electrostatic attraction between pairs of oppositely charged ions. Usually the metal atom loses electrons to become a positively charged cation where as the non metal atom gains electrons to b...

The first ionisation energy is the energy required to remove an electron from a gaseous atom.
The equation for the first ionisation of Chlorine is: Cl (g) --> Cl+ (g) + e-

NaCl is an example of a covalent structure, where electrons are shared between the atoms in covalent bonds. Graphite has a giant covalent structure with the covalently bonded carbon atoms arranged in laye...

Sodium is on group 1 and has 1 election in its outer shell. Chloride is in group 7 and has 7 electrons in its outer shell.Sodium looses 1 electron and chlorine gains 1 electron giving both atoms a full ou...
