Atoms that have on outer (valence) shell composed of less than or equal to 4 electrons.
When halogens form ions, they are called halide ions. These types of ions have a negative charge due to gaining electrons.
Ions are cations (positive) or anions (negative).
Atoms gain electrons to form negatively charged anions. Atoms lose electrons to form positively charged cations.
Arsenic atoms are neutral and they form ions with valency of three.
Gaining 2 electrons gives the O atom the stable octet of electrons.
Negative ions are formed when atoms accept electrons.
Negative ions form when atoms GAIN valence electrons.
Because they want to.
Non Metals

Yes, only if there are both ions with positive charges and ions with negative charges among the ionized atoms.
Ions are atoms that have a postive or negative charge because they have loss or gained negative particles (electons).
Arsenic atoms are neutral and they form ions with valency of three.
They can do both to form ions. An ion simply means that there is an uneven distribution of charge, so it can be positive or negative.
