It depends! if an ion has 7 electrons on its outter region and it decides to gain 1 that would make it stable! if you have 8 on your second region and have an extra electron, you can loose it and the ion will be stable again!
You're thinking of polyatomic ions. These are groups of (usually) covalently bonded atoms which function together as a single unit, with a single overall charge, usually negative. They bond ionically with metals and occasionally other polyatomic ions that have a positive charge (though there aren't many like that.) Common examples are sulfate (SO4-2), hydroxide (OH-1) and phosphate (PO4-3).
Anions are negatively charged ions formed by gaining electrons.
Cations are positively charged ions formed by losing electrons.
(polyatomic)
The ions of molecules rather than atoms.
Thus sulfuric acid gives sulfate (-) and H (+) [ or really H3O+].
An atom that has lost or gained electrons is known generally as an ion. More specifically, an atom that has lost electrons becomes a cation. It has a positive charge. An atom that has gained electrons becomes an anion. An anion has a negative charge.
usually a new substance is formed, but the substance formed depends on the reagants used molecule
-3 electrons are gained,i.e,3 electrons are lost by Al and 3 electrons are gained by the other atom nearby.
Since valency of oxide is 2 which is formed when electrons are gained by oxygen , hence valency of oxygen is also 2
The bond formed when two atoms have a give-take relationship in relation to electrons is called ionic bonding. This will mostly happens so that atoms can gain stability.
No. Monatomic means there is only a single atom, this cannot be covalently bonded as this implies there are two or more atoms. Yes they have either gained or lost electrons.

An ionic bond between the ions (formed from the atoms).
Ionic bonds are formed between positively charged atoms (lost electrons) and negatively charged atoms (gained electrons).
An element is composed of only one kind of atom and cannot be broken down chemically. A compound is composed of atoms of two or more elements chemically bonded, and are either ionic or molecular. An ion is an atom that has gained or lost one or more electrons, developing a negative or positive charge, respectively. A molecule is two or more atoms covalently bonded.
ionic bond is formed by the complete transfer of electrons
Ionic bond is formed between the ions.
Calcium hydroxide has groups of covalently bonded atoms that have either lost or gained electrons. It is an ion made up of two or more atoms that are covalently bonded and that act like a single ion. ~Ayanna~ Your answer doesn't answer the question. ****************** This answer will: The covalent part is between the O-H of the hydroxide. In this instance, O and H always bond covalently. Calcium's bond with the OH, which is a separate subject, is ionic, as in Ca ++ : (OH -) x 2 Almost all compounds involving metals are ionic, so this is typical. That should clear it up
Polyatomic This is for you A+ users
It is larger, because it has gained electrons.
