Periodic Table

Question 0

What are characteristics of elements to the right side? (Non-metals)

Answer 0

Poor conductors
Dull, soft, liquid, solid and gas at room temp.
Gain valence electrons (anions)

Question 1

What are characteristics of elements to the left of the line? (Metals)

Answer 1

Good conductor
Shiny, hard, ductile, solid at room temp.
Lose valence electrons (cation)

Question 2

What are the diatomic elements?

Answer 2

H, N, O, F, Cl, Br, I (all 2)

Question 3

Alkali metals (group 1) characteristics

Answer 3

Most metallic
Soft metals
Very reactive

Question 4

Alkaline earth metals (group 2) characteristics

Answer 4

Reactive, but not as much as group 1

Question 5

Transitional metals characteristics

Answer 5

Multiple oxidation number and different numbers of valence electrons

Question 6

Halogens (group 17) characteristics

Answer 6

Very reactive
Non-metals
Form anions

Question 7

Noble gases characteristics

Answer 7

Non reactive

Question 8

Oxidation number

Answer 8

The charge of an ion (must equal 8)

Question 9

Atomic radii

Answer 9

Size of an atom

Closest to Fr (down and left)

Question 10

Ionic radii

Answer 10

Size of the ion
Cations are smaller
Anions are larger

Question 11

Ionization energy

Answer 11

Energy required to steal elections away

Closest to He

Question 12

Electronegativity

Answer 12

Unequal sharing of electrons, measure of an atom’s ability to steal electrons
(Closest to F)

Question 13

Reactivity

Answer 13

How likely an atom reacts with another atom

Depends on how easily electrons can be gained or lost
