13 cards from this deck
2 electrons in 1st shell, 8 in outer shells
When atom has full outer shells (2-8 rule satisfied)
Closely packed with strong bonds, cannot move freely
Roll over each other with ease but remain attracted
Attracted but not strictly bound, move freely with space
Covalent, ionic, metallic
Atoms share electrons from outer shells
Primary bonds - very strong and difficult to break
A charged atom (positively or negatively charged)
Bond formed when charged ions attract electrostatically
Secondary bonds - weaker, can be broken with heat
Sea of delocalised electrons around positive metal atoms
Delocalised electrons can move freely through metal
