Ok very easy question, lets simplify it for you.

are you still online @KateyMae7 ?

No.  I'm not.  Responding to a two day old question is somewhat hilarious.  I paid money to try and get someone to explain this to me, and then someone replies two days later.  Yeah, huge waste of money.

Make sure a qualified helper is online before you post, otherwise I'm sure @Preetha Can do something for you since you didn't get help right away.

Potassium has 1 valence electron in its outer shell (group 1A) . Nitride is a charged species of Nitrogen with a -3 oxidation state. An N ion. This means the Nitrogen has 3 additional electrons. Since neutral nitrogen has 5 Valence, if you chuck in 3 more, it will have 8. If you look at the periodic table, http://www.drcruzan.com/Images/Chemistry/IonicCompoundsPerTable.png Nitrogen is in group 5A which has 5 valence electrons, nitrogen also has a 3- charge which means it gains 3 more valence electron. 5+3=8 I'm not a qualified helper, but I suggest you ask your question publicly first before asking a qualified helper, since it was quite simple.
