Bingo Game for Chemical Bonding with ionic and covalent compounds

A fun way to review Bonding in high school is to have students play a bingo game. They can work individually, pairs, or even teams. This is a great way to review for a test. The teacher is provided with a list of 26 terms and the appropriate concept/description. This packet includes 30 different Bingo cards (two per sheet) with the terms randomly positioned. The topics and terms include, but are not limited to ionic, covalent, polar, non-polar, symmetrical, asymmetrical and metallic.

New York State Objectives:
Commencement Level Physical Setting, Chemistry
IV.2Two major categories of compounds are ionic and molecular (covalent) compounds. (5.2g)
IV.3 Chemical bonds are formed when valence electrons are (5.2a):
• transferred from one atom to another (ionic)
• shared between atoms (covalent)
• mobile within a metal (metallic)
IV.4 In a multiple covalent bond, more than one pair of electrons are shared between two atoms. (5.2e)
IV.5 Molecular polarity can be determined by the shape of the molecule and the distribution of charge. Symmetrical (nonpolar) molecules include CO2, CH4, and diatomic elements. Asymmetrical (polar) molecules include HCl, NH3, and H2O. (5.2l)
IV.6 When an atom gains one or more electrons, it becomes a negative ion and its radius increases. When an atom loses one or more electrons, it becomes a positive ion and its radius decreases. (5.2c)
IV.7 When a bond is broken, energy is absorbed. When a bond is formed, energy is released. (5.2i)
IV.9 Physical properties of substances can be explained in terms of chemical bonds and intermolecular forces. These properties include conductivity, malleability, solubility, hardness, melting point, and boiling point. (5.2n)
IV.11 Electronegativity indicates how strongly an atom of an element attracts electrons in a chemical bond.
Electronegativity values are assigned according to arbitrary scales. (5.2j)
IV.12 The electronegativity difference between two bonded atoms is used to assess the degree of polarity in the bond. (5.2k)
IV.13 Metals tend to react with nonmetals to form ionic compounds. Nonmetals tend to react with other nonmetals to form molecular (covalent) compounds. Ionic compounds containing polyatomic ions have both ionic and covalent bonding. (5.2h)
