Cation
positively charged ion - smaller than the neutral atom
Anion
negatively charged ion - larger than the neutral atom
Properties of Metals
solid at room temp., hard, shiny, strong, ductile, malleable, and conductive
Location of Metals
left side and middle of the periodic table
Properties of Metal Electrons
usually has 1, 2, or 3 valence electrons and they tend to lose electrons to form positive ions (cations)
Nonmetal Properties
brittle, poor conductors, not shiny, soft, dull, high ionization energy
Location of Nonmetals
right side of periodic table
Properties of Nonmetal Electrons
usually has 4-8 valence electrons and tends to gain electrons (forms anions)
Metallic Bond
a bond exclusively between metals with a bulk of metal atoms that are clumped together
Metallic Bond Electrons
the electrons move freely within molecular orbits, so each electron becomes detatched from its parent atom
Ionic Bond
a chemical bond formed when one atom gives up one or more electrons to another atom
Ionic Bond Electrons
the electrons transfer one or more electrons between atoms
Covalent Bond
a bond formed between two or more nonmetals where the nonmetals will share electrons to complete their octet (except H, Be, and B)
Number of valence electrons
based on the group number
