Answer 6

Low melting and boiling points
Many gasses at room temp
Poor conductors of electricity (excep graphite - a form of carbon)
Brittle (break when hit)
Dull
Less dense
None are magnetic

Question 9

Electrons

Answer 9

Found : shells
Charge : -1
Mass : 1/2000

Question 10

Number of protons

Answer 10

Equals the number of electrons because all atoms are neutral

Question 11

Atomic number

Answer 11

Number of protons

Question 12

Atomic mass

Answer 12

Protons + neutrons

Question 13

Atomic mass - atomic number

Answer 13

Neutrons

Question 14

Isotope

Answer 14

Atoms of an element with the same number of protons but a different number of neutrons

Question 15

Calculation for relative atomic mass

Answer 15

(Mass of isotope x % of isotope) + (mass of isotope x % of isotope) / 100

Question 16

Groups

Answer 16

The group number is how many electrons they have ink their outer shell

Question 17

Period number

Answer 17

is how many shells there are
