A
Positive ions
3
Q
Are the atoms in metals closely packed together?
A
Yes
4
Q
What are the electrons in the outer shell like?
A
Free to move throughout metallic lattice, creates strong metallic bonding
5
Q
Do most metals have high or low melting and boiling points?
A
High
6
Q
What are alloys?
A
Mixtures of a metal with other elements
7
Q
Why are alloys harder than pure metals?
A
Layers are distorted and cannot slide
8
Q
Why are metals good conductors of ELECTRICITY?
