Reactivity

Question 1

Atomic radius

Answer 1

one-half the distance between nuclei of identical atoms
# of protons, greater force of attraction- makes atom smaller
Trend: left and down increasing

Question 2

Ionization Energy

Answer 2

Energy required to remove one electron
# of rings- distance increases
shielding effect caused repulsion to remove v.e. easier
Trend: Up and right increasing

Question 3

Shielding

Answer 3

Prevent outer electrons from “feeling” attracted to nucleus

Question 4

Ionization importance

Answer 4

determine reactivity
high ionization less it wants to react

Question 5

electro negativity

Answer 5

measurement of an atom in a chemical compound to attract an electron from another atoms in the compound

Trends Increased up and right

Question 6

Reactivity

Answer 6

Metal reactivity isn’t the same as non metal reactivity

Question 7

Most reactive metal

Answer 7

Francium (has more rings)

Question 8

Non- reactive non metal

Answer 8

Fluorine (needs to gain electron)
