CH4

Question 1

delocalized

Answer 1

-means the valance electrons are able to wonder around freely throughout the entire crystal.
-The atoms that electrons leave behind become positive ions.
-The attraction between positive ions and valance electrons is the force that holds the metallic crystals together

Question 2

Metals

Answer 2

metals are solid at room temp and exist as crystal latices.

Question 3

how are metals connected

Answer 3

They are closely packed, and the valence shells of each metal atom overlap the one next to them.
-This allows the electrons to move freely from one atom to another (they aren’t associated with any specific atom

Question 4

Electricity

Answer 4

-Delocalized electrons are what allow metals to conduct electricity.
-when an electrical field is aplied across a metal wire, the randomly moving electrons all start to move in one direction forming an electrical current

Question 5

what is an electrical current

Answer 5

electrical current is the movement of electrons.
