A period. 3 of 15 What do elements in the same period have in common? The number of occupied (full) shells. 4 of 15 What does an electronic structure of an element show? The number of electrons in each shell. 5 of 15 What are the three types of bonding? Ionic, covalent, metallic. 6 of 15 Between what type of molecules does covalent bonding occur? Non-metals. 7 of 15 What type of bonding occurrs with sharing pairs of electrons? Covalent. 8 of 15 What is the intermolecular force of attraction between molecules in covalent bonding like? Weak. 9 of 15 Do covalently bonded molecules have low or high melting points? Low. 10 of 15 Can covalently bonded molecules conduct electricity? Why?
