Document Summary
Properties of non-metals:- brittle (cannot be drawn into wires or thin sheets)- non-conductive (very poor at transferring heat or electricity) - Not very reactive (there are exceptions, such as fluorine) Metalloids are elements that fall into the section between transition metals & the non-metals on the periodic table and have properties of both metals & non-metals. Ionic bonding occurs between two ions of the opposite charge. Cation: a positively charged ion- anion: a negatively charged ion. However, when we look at diatomic ionic bonding (or two atom ionic bonding), it usually occurs between a metal and a nonmetal. In fact, they must satisfy the octet rule, or have the maximum number of electron on its outermost shell. Except for the noble gases, none of the elements have full octets. There are 3 types of bonding, one of them being ionic bonding. Ionic bonding works by the exchange of electrons between the elements.
