group 0 elements

Question 1

how many electrons do group 0 elements have on their outer shell?

Answer 1

8 (other than helium)

Question 2

what is special about noble gases?

Answer 2

they have a full, stable shell of electrons

Question 3

what are group 0 elements at room temp?

Answer 3

colourless gases

Question 4

inert

Answer 4

unreactive

Question 5

list 3 properties of group 0

Answer 5

non-flammable
inert
low boiling point (gas at room temp)

Question 6

describe the trend in boiling points going down the group 0?

Answer 6

it increases

Question 7

describe the trend in atomic mass going down the group 0?

Answer 7

it increases

Question 8

why does the boiling point increase going down the group?

Answer 8

there is an increase in the number of electrons in each atom, leading to greater intermolecular forces between them which need to be overcome

Question 9

why are group 0 elements unreactive?

Answer 9

they have a full valence shell so no tendency to gain/lose any electrons

Question 10

what type of atoms do they exist as?

Answer 10

monoatomic
