reactive out of the three. Sodium follows, being the leftmost out of the remaining two. Magnesium is therefore the least reactive. 8. Ionization energy refers to the amount of energy needed for an element to ionize (gain or lose 1 electron), while electronegativity refers to the energy holding the electrons in orbit. An element with less electronegativity has a weaker hold on the electrons in orbit, making it easier for those electrons to transfer to another atom, hence ionizing.

In an ionic bond, the metal transfers electron(s) to the non-metal, while in a covalent bond, the non-metals share electrons. In an ionic bond, there is a metal involved, while in covalent bonds, there are no metals and only non-metals. In an ionic bond, the metal will be positively charged and the non-metal will be negatively charged. In a covalent bond, all non-metals are neutrally charged. 11. a) KBr (ionic) b) CaCl 2 (ionic) c) Li 2 O (ionic) d) SiCl 4 (covalent with 4 single bonds)
