The ionic charges of group 1 and 2 metals are +1 and +2 respectively. Group 15 & 16 the simple mono-atomic ions are -3 and -2. Group 17 ions are -1. This can be explained by the following elemnts in groups 1 and 2 lose 1 or 2 electrons respectively to achieve a noble gas configuration whereas groups 15, 16 and 17 gain electrons (3,2 1 respectively)

Groups 14 and 15 on the Periodic Table feature elements which are metals, non-metals, and metalloids.
Which groups of elements are most likely to be held together by covalent bonds?
Non metals (groups 17, 16, 15)
What type of ions have name ending in -ide?
Those ions areall anions,negatively charged (mainly) -1, -2 or -3,consisting of one nonmetal element (mainly group 17, 16 or 15 respectively) andnot containg oxygen.Examples:17: F- , Cl- , Br- , I- (fluoride, chloride, bromide, iodide)16: O2-(oxide), S2-(sulfide)15: N3- (nitride), P3- (phosphide)

Is group fifteen an ionic compound on the periodic table?
Group 15 elements generally form covalent compounds. However the two elements from group 15 nitrogen and phosphorus are known to form nitride (N3-) and phosphide (P3-) ions as in Na3N or Na3P.
What type of ethnic groups are in Somalia?

What groups are nitrogen and oxygen in?
Groups 15 and 16, respectively.

15
Which three groups of the periodic table contain the most elements classified as metalloids?
Groups 13, 14 and 15
Do p-block elements tend to form negative ions that have electron configurations resembling alkali metals or noble gases?
The p block elements are usually considered to include groups 13 14, 15, 16, 17, 18. Of these the non metals N and P from group 15, O, S, Se from group 16 and all of group 17 form anions which have noble gas configurations. The metals generally form cations, the highest oxidation state these have noble gas configurations but many exhibit a lower oxidation state as well. The metalloids can form anions but these do not follow simple valency rules.
