Ionic bonds form during chemical changes when atoms pull electrons away from other atoms. The atoms that lose electrons form ions that have fewer electrons than protons. So, an ion would be produced by an atom or a group of atoms that gained or lost one or more of its electrons.
ion
An ion.
A covalent bond is formed by shared electrons. If 2 atoms share electrons, then even if the sharing is not perfectly equal (as in the case of, for example, carbon monoxide) you do not get a negative ion and a positive ion, as you do when electrons are actually transferred from one atom to another. You get at most a minor amount of charge, not a whole charge on an atom.
Yes. When an atom loses electrons, it becomes a positively charged ion called a cation. When an atom gains electrons, it becomes a negatively charged ion called an anion.

No, when they 'share' electrons they don't tranfer electron(s) from one to the other atom. This would be necessary for an ionic bond, between a cation (+ charge) and anion (- charge) Sharing electrons give covalent bonds.

Nitrogen atoms gain 3 electrons and form the nitride ion, N3-. Nitrogen atoms also form covalent bonds where they share 3 electrons and do not become ions. Bromine atoms gain 1 electron and form the bromide ion, Br-. Bromine atoms also form covalent bonds when they share 1 electron and do not become ions.
Yes: Carbon can gain 4 electrons from less electronegative elements to form a carbide ion with a charge of -4 in an ionic compound. (More often, however, a carbon atoms will share four electrons with other atoms to form covalent bonds.)
If atoms lose electrons they will have a positively charged ion called a cation. If they gain electrons, they will have a negatively charged ion called an anion.
They generally don't share anything... in balenced atoms there is the same amount of protons and electrons so that the atom has an overall no charge... if you loose an electron you get a positvly chared ion particle and vice versa if you loose a proton (you get a negatively charged ion) this is because protons have a positve charge and electrons have a negative charge...

Hydrogen itself is an atom. If that hydrogen atom were to lose/gain/share electrons it would become an isotope/ ion
