ANSWER:Solution 93P
Here, we have to determine the number of neutrons in an atom with each atomic number and mass number
An atom is made up of subatomic particles called protons, neutrons and electrons. Protons and neutrons make up the nucleus and electrons revolve around the nucleus. An atom is represented as :
ZAX.
Here, ‘A’ represents Mass number.
‘Z’ represents Atomic number.
- Atomic number indicates the number of protons and electrons.
- The difference between number of protons and mass number determines the number of neutrons as the number of protons and neutrons make the mass number.
(a) Z = 28, A = 59
The atomic number given here is 28 and the mass number is 59. The element having atomic number 28
