Are the bonds between silicon and chlorine in silicon tetrachloride single bonds? justify your answer by drawing an electron dot structure of silicon tetrachloride.

A bond is a force of attraction between atoms as a result of transfer or sharing of electrons. Covalent bond is a bond between non metal atoms that results from sharing of electrons between the atoms. A single atom is formed when atoms share a pair of electron during formation of covalent bonds. Therefore, single covalent bonds exist in a molecule of carbon tetrachloride ( 4 single covalent bonds )

☆ionisation energy increases across a period from na -> ar☆ionisation energy decreases down a group from li -> fr☆ionic radius decreases across a period from na -> cl☆ionic radius increases down a groupfrom f -> ii hope it clarifies your doubts

The closer the atoms are to becoming ionic the more highly dense the negatively charged side gets.
