200
An element that is not a good conductor of electricity and heat.
What is a non-metal?
200
The property Mosely used to organize the periodic table.
What is atomic number?
200
The process where an atom may gain or lose valence electrons so that its outermost energy level is full.

Increase
300
Which has a bigger size: Mg or Ba?
Ba
400
Another word for semiconductor.

400
A negative ion.
What is an anion?
400
How does electronegativity change as you go down a group?
Decrease
400
Which has a bigger size: Po or Bi?
Bi
500
A measure of the tendency of an atom to attract a bonding pair of electrons.
What is electronegativity?
500
The arrangement of electrons in energy levels around an atomic nucleus.

500
A positive ion.
What is a cation?
500
How does electronegativity change as you go across the periodic table?
Increase.
500
How does electronegativity relate to the size of an atom?
Higher electronegativity = smaller size
