They generally form covalent compounds, but still they form -3 valency ions.
Main group metals tend to lose electrons, forming a cation with the same number of electrons as the nearest noble gas. A main group nonmetal tends to gain electrons, forming an anion with the same number of electrons as the nearest, previous noble gas
Phosphorus ions typically have a negative charge, specifically a charge of -3. This is because phosphorus belongs to group 15 of the periodic table, which typically gains three electrons to achieve a stable electron configuration.
Phosphorus is number 15 on the Periodic Table of Elements. The most common charge is -3 because it needs three more electrons to fill it's outer shell.
In an ionic compound the charges must balance out to zero. Since the nitride ion has a 3- charge and sodium forms a 1+ ion so in sodium nitride there are three sodium ions (Na+) fore every one nitride ion (N3-).
Barium is a group 2 metal that typically forms a +2 ion, while nitrogen is a group 15 nonmetal that typically gains three electrons to form a -3 ion. Therefore, the most likely charges for ions formed from barium and nitrogen would be Ba2+ and N3- respectively.

1: 1+ 2: 2+ 13: 3+ 14: 4+/- 15: 3- 16: 2- 17: 1- 18: Neutral Transition metals (elements between groups 2 and 13) are able to have varied charges that there is no real rule for.
In compounds with elemnts with low electronegativity compounds N3-, P3- etc are found.
There's no charge within the atom of each group since there is a same number of electrons (negatively charged) and protons ( positively charged). The charge does not change unless after ionic bonding. The atomic charge changes depending on the reaction.
Non-metal ions typically have a charge that corresponds to the number of electrons they need to gain to achieve a stable electron configuration, usually by gaining enough electrons to fill their outermost energy level. For example, elements in Group 15 usually gain three electrons to form ions with a 3- charge, while those in Group 17 usually gain one electron to form ions with a 1- charge.
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)
The ionic compound of Ra and N would be radium nitride (Ra3N2). Radium is a group 2 metal with a 2+ charge, while nitrogen is a group 15 nonmetal with a 3- charge. To balance the charges, two nitride ions are needed for every three radium ions, resulting in the formula Ra3N2.
Group 15 elements have 5 valence electrons. They accept three electrons and form anions of -3 charge. For example: N3- (nitride ion) or P3- (phosphide ion)
Phosphorus is number 15 on the Periodic Table of Elements. The most common charge is -3 because it needs three more electrons to fill it's outer shell.
In an ionic compound the charges must balance out to zero. Since the nitride ion has a 3- charge and sodium forms a 1+ ion so in sodium nitride there are three sodium ions (Na+) fore every one nitride ion (N3-).
The ionic compound for sodium nitride is Na3N. Sodium (Na) is a group 1 element with a +1 charge, while nitrogen (N) is a group 15 element with a -3 charge. The compound is formed by combining these ions in a 3:1 ratio to balance the charges.
