BONDING IN METALS

Question 1

metallic bond

Answer 1

the attraction between a positive metal ion and the electrons around it.

Question 2

facts about metals

Answer 2

1. they have 1, 2, or 3 valence electrons
2. they easily lose electrons
3. metals consist of positively charged metal ions in a “sea” of valence electrons.

Question 3

solid metals

Answer 3

1. .solid metals are crystals with positive atoms
2. .metal atoms in the crystals are very close together
3. they conduct heat and electricity and can change shape easily, and have luster.

Question 4

metallic properties

Answer 4

1. valence electrons are lose so heat travels easily
2. electricity flows b/c charged particles are free to move
3. you can easily change shape b/c metal ions are not attracted to other ions.
4. they are DUCTILE
5. they are Malleable

Question 5

ductile

Answer 5

a metal can be bent easily and pulled into a wire

Question 6

malleable

Answer 6

a metal can be rolled into thin sheets or beaten into a shape.

Question 7

luster

Answer 7

when light strikes ve the electrons absorb the light and give it off again. it makes them look shiney.
