ISCI 101 Study Guide - Final Guide: Noble Gas, Nonmetal, Electronegativity
Document Summary
Octet rule: when atoms of elements react, they tend to lose, gain, or share electrons to achieve the same electrons arrangement as noble gas nearest to them in the periodic table. Electronegativity: a measure of the relative tendency of an atom to attract electrons to itself. Ionic bonding: transfer electron between metal and nonmetal. Ion formation: loss or gain electrons; cations & anions. Single: 2 atoms share a single pair of electrons. Double: 2 atoms share 2 pairs of electrons. Triple: 3 atoms share 3 pairs of electrons. A metallic element a number of a. Polar: formed when 2 atoms with different abilities to attract electrons bonded covalently.
