Consider NaCl and CCl4, the first compound is dominated by ionic bonding, whereas the second covalent.

Ionic bonding involves a cation (Na+) and an anion (Cl-), where strong electrostatic interacti...

NaBH4

Generally, molecules are coloured as they absorb visible frequencies of light, to promote an electron to a higher energy level, so the other (complementary) frequencies of light pass through the sample an...

So, when two molecules are bonding to each other they are always trying to achieve the same state, which is having a full outer shell of electrons. Ionic and Covalent bonding are two different ways of get...

Halogens. Boiling point increase as you go down the group. (This is because the size of the molecules increase as you go down the group, which increases the strengths of van der Waals forces)
