Beryllium makes two bonds (it is the only element in group 2 to make covalent compounds). The number of electrons required to make an octet determines the number covalent bonds an electron can form. When fully bonded to other atoms, the four bonds of the carbon atom are directed to the corners of a tetrahedron and make angles of about 109.5 with each other ( see chemical bonding: Bonds between atoms ). The number refers to the number of bonds each of the element makes: What is the maximum number of bonds an atom can form? Is fluorine likely to form a covalent bond?
