Nonmetals because they have a lot of valence electrons.
If you're talking about ionic compounds, which generally form between metals and nonmetals, the nonmetal will gain one or more electrons when forming an ionic bond.

Bonds are formed on sharing electrons. Covalent bonds are formed.
Chemical bonds are formed by the sharing or donating of electrons. The electrons that atoms use to make chemical bonds are the outermost electrons, also known as valence electrons.
This is called a covalent bond.
Ionic bond; ionic bonds occur when an element, mainly a metal, loses its electron ( to become positively charged) to an other element, mainly a nonmetal, ( to become negatively charged), to form an ionic compound. For example :- Na + Cl = NaCl

Bonds are formed on sharing electrons. Covalent bonds are formed.
Covalent bonds are formed when electrons are shared between atoms.
Covalent bonds are formed when non-metals share electrons. Ionic bonds are formed when metals and non-metals lose and gain electrons.
Once formed there is NO difference from other covalant bonds. Coordinate covalent bonds only differ from other covalent bonds because a single element donates all the electrons that are to be shared.
If an element has less than four valence electrons, it will tend to lose its valence electrons and form cations. If an element has more than four valence electrons, it will tend to gain electrons and form anions. An element that has four valence electrons will tend to form covalent bonds rather than ionic bonds.
Silicon is an element in group 14. It has four valence electrons. Silicon tends to share electrons rather than releasing or obtaining four electrons (which needs tremendous energy). Hence it forms covalent bonds.
False
when an element donate it's electrons and another element acceps it,in order to complete the octet electronic configuration,ionic bonds are formed
ionic bonds!
Covalent bonds are bonds formed by the sharing of electrons.
