Answer:
0.25
Explanation:
volume= number of moles over concentration
hence v=1.5/6
Ions have a negative or positive charge because silver is metal. It is a cation (Ion with a positive charge).
It depends on the number of valence electrons required to make octet or duplet( in case of H)
. For example, Nitrogen(atomic number = 7) has electronic configuration(2,5) which means nitrogen has 5 valence electrons and requires 3 more electrons to complete its octet. After gaining 3 electrons from atoms of an element with less electronegativity than N, it forms nitride ion (![N ^{-3}](https://tex.z-dn.net/?f=N%20%5E%7B-3%7D%20)
).
Hope this helps.
