Question 2.3: How many neutrons and protons are there in the following nuclei?
Answer
1) Atomic mass = 13
Atomic number = Number of protons = 6
Number of neutrons = (Atomic mass) - (Atomic number) = 13 - 6 = 7
2)Atomic mass = 16
Atomic number = 8
Number of protons = 8
Number of neutrons = (Atomic mass) - (Atomic number) = 16 - 8 = 8
3)Atomic mass = 24
Atomic number = Number of protons = 12
Number of neutrons = (Atomic mass) - (Atomic number) = 24 - 12 = 12
Answer
1) Atomic mass = 13
Atomic number = Number of protons = 6
Number of neutrons = (Atomic mass) - (Atomic number) = 13 - 6 = 7
2)Atomic mass = 16
Atomic number = 8
Number of protons = 8
Number of neutrons = (Atomic mass) - (Atomic number) = 16 - 8 = 8
3)Atomic mass = 24
Atomic number = Number of protons = 12
Number of neutrons = (Atomic mass) - (Atomic number) = 24 - 12 = 12
