Why does group 4A elements tend to form covalent bonds rather than ionic bonds? 
Group-14 elements share electrons. they form covalent bonds.
the group 4A elements
Elements in group 1 are called Alkali Metals, after that group 2 elements are called Alkali Earth Metals, group 3-12 elements are called Transition Elements.
Elements of group 4a are used as semi-conductorse.g. silicon,germanium etc.

the group 4A elements
Elements in group 1 are called Alkali Metals, after that group 2 elements are called Alkali Earth Metals, group 3-12 elements are called Transition Elements.
Groups 3-12 have elements with the most diverse set of properties in the periodic table. They are transition elements.
Group 17 elements are called the halogens. Group 18 elements are called the noble gases.
