Aluminum
Nitrogen
Helium
Fluorine

Use the following table to answer the question Which element has the least neutrons in the nucleus Aluminum Nitrogen Helium Fluorine class=

Respuesta :

Answer:

Explanation:

Aluminium , mass no = no of proton + neutron = 27

atomic no = no of proton = 13

no of neutron = 27 - 13 = 14

Nitrogen  , mass no = no of proton + neutron = 14

atomic no = no of proton = 7

no of neutron = 14 - 7 = 7

Helium   , mass no = no of proton + neutron = 4

atomic no = no of proton = 2

no of neutron = 4 - 2= 2

fluorine    , mass no = no of proton + neutron = 19

atomic no = no of proton = 9

no of neutron = 19-9 = 10

Answer:

Helium

Explanation:

I understood the explanation the last guy gave

helium only had two neutrons
