3 0
The number of electrons in the outermost shell of an atom determines its reactivity. EX: noble gases have a low reactivity because they have a full electron shell, and don't need any more outermost ones.
EX: halogens are highly reactive because they readily gain an electron to fill their outermost shell

Why is water called "polar"?
Brilliant_brown [7]

Water (H2O) is polar because of the bent shape of the molecule. The shape means most of the negative charge from the oxygen on side of the molecule and the positive charge of the hydrogen atoms is on the other side of the molecule. This is an example of polar covalent chemical bonding. When solutes are added to water, they may be affected by the charge distribution.
