9 Name IONIC and COVALENT BONDING LAB ACTIVITY, PROCEDURE and REPORT SHEET BIG IDEAS: ectron configurations determine how atoms combine to form chemical bonds. 2. According to the valence bond theory, the outermost electrons of atoms, the valence electrons, are the ones involved in bonding. 3. Atoms of elements can LOSE, GAIN, or SHARE electrons so that each atom involved achieves a noble gas electron configuration. This is known as the OCTET RULE 4. When atoms lose or gain electrons,...

Answer true or false. 1. Atoms that lose electrons to achieve a filled valence shell become cations and form ionic bonds with anions. 2. Ionic bonds tend to form between elements on the left side of the Periodic Table, and covalent bonds tend to form between elements on the right side of the Periodic Table. 3. Electronegativity is a measure of an atom's attraction for the electrons it shares in a chemical bond with another atom. 4. Fluorine, in the...
