i think u mean Ionic bonds. and a cation and anion make ionic bonds. Cations are positive and usually metal (with the exception of Mercury and hydrogen). and anions have a negative charge and is usually a nonmetal.
Group-14 elements share electrons. they form covalent bonds.
Why does group 4A elements tend to form covalent bonds rather than ionic bonds? 
Rule of thumb answer is covalent bonds form between non metal elements.
they form elements
Both Br and Br and H and H form non-polar covalent bonds.
iconic bonds
Covalent bonds, (single, double, triple)
Electrons, specifically valence electrons are shared when elements form bonds.
Group-14 elements share electrons. they form covalent bonds.
Elements form bonds because of the attractions between atoms or ions. There are several types of bonds such as ionic, covalent and metallic bonds.

This element is carbon.
The properties of the elements are changed.
Noble gases do not usually form chemical bonds.
