Q

Non-polar solvent

A

A liquid or solvent that is a compound of two or more elements whose electronegatives are almost the same. Eg: Oil

17
Q

Octet rule

A

A rule used as part of the explanation for electron configuration and in bonding. The rule is that during a chemical reaction, atoms tend to lose, gain or share their valen electrons so that there are eight electrons in the outer shell

18
Q

Polyatomic ion

A

An ion that is made up of more than one element eg: Carbonate ion CO3(lower)2-(Upper)

19
Q

Salinity

A

The presence of Salt in water and soil that can damage plants or inhibit their growth
