Good Conductor
Always Exothermic when bonds form or break
Contains atoms with a net charge

EXTRA CREDIT: Explain the three steps required to form an ionic bond. Make sure you state which substances (metals, nonmetals, metalloids) are involved, what happens to the valence electrons (and why) and what this causes the atoms to do.
use the terms high/low electronegativity, cation/anion, opposite attraction

Rank the folowing physical properties as Metals, Nonmetals or Metalloids. NO OPTION WILL BE USED TWICE. Pick whatever the BEST answer is for each physical property.

Roughly 7 elements on the periodic table
Gas at room temperature
Semi-conductor
Ductile
Low Electronegativity
Shiny with good luster
Good Insulator
A brittle solid at room temperature
Malleable
High Electronegativity (only High)
Dull with poor luster
Good Conductor

I'm asking if nonmetals are involved in both types of bonds.
