Because they want to.
Positive ions
Atoms gain electrons to form negatively charged anions. Atoms lose electrons to form positively charged cations.
Metals tend to form positive ions also known as cations.
That's correct! When atoms gain or lose electrons, they become ions with an overall positive or negative charge. Positive ions are called cations, and negative ions are called anions.
Arsenic atoms are neutral and they form ions with valency of three.
Yes, only if there are both ions with positive charges and ions with negative charges among the ionized atoms.
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.
A polyatomic ion is a group of atoms with a charge.
Yes, if they are ions
Negative ions are formed when atoms accept electrons.
Metals form positive ions and form ionic compounds with negative ions.
Positive ions (or cations) are formed when atoms lose electrons
