The Periodic Table

Question 0

The group number indicates..

Answer 0

The number of electrons on the outer shell

Question 1

The row number indicates..

Answer 1

How many electron shells there is

Question 2

Group I is..

Answer 2

Alkali metals (Lithium, Sodium, Potassium) [Li, Na, K]

Question 3

Properties of Alkali metals

Answer 3

Extremely reactive, stored under oil, one electron in outer shell, can be cut easily with a knife, lose their shine in oxygen, low melting point, float in water, in water they fizz and sometime catch fire

Question 4

Reaction of lithium and water

Answer 4

Lithium and water -> lithium dioxide and hydrogen

2Li + 2H2O -> 2LiOH + H2

Question 5

Reaction of sodium and water

Answer 5

Sodium + water -> sodium hydroxide + hydrogen

2Na + 2H2O -> 2NaOH + H2

Question 6

Reaction of potassium and water

Answer 6

Potassium + water -> potassium hydroxide + hydrogen

2K + 2H2O -> 2KOH + H2

Question 7

Group II is..

Answer 7

Alkaline/earth metals

Question 8

Properties of alkaline/earth metals

Answer 8

2 electrons in outer shell, very reactive, do not need to be stored under oil, do not fizz as much or catch fire

Question 9

Group VII is..

Answer 9

Halogen (fluorine, chlorine, bromine, iodine) [F, Cl, Br, I]

Question 10

Properties of halogens

Answer 10

7 electrons in outer shell, get less reactive as you go down the group

Question 11

Group VIII is..

Answer 11

Noble gases

Question 12

Properties of noble gases

Answer 12

Full outer shells, inert/chemically inactive
