Question

What is the symbol for an isotope that contains 12 neutrons and 10 protons?

Select one:

a. Ne-12

b. Mg-22

c. Ne-22

d. Mg-12

Answer 1

Answer #1

Number of proton 10

Number of neutron 12

Atomic number equal to number of proton 10=neon

Mass number=number of proton+ neutron=10+12=22

So symbol of isotope is Ne1022

Option C is correct

Answer 2
