Question

An atom has mass number is 16 and atomic number is 7 then what is the number of Protons, Electrons and Neutrons in an atom ?​

Answer 1

Answer:

number of protons = 7 (atomic number)

number of neutrons= 16-7 =9( mass number -number of protons)

number of electrons = 7( number of electrons and protons are equal in neutral atom)

Answer 2

(mass no)protons+neutrons = 16

(atomic no.)no. of protons = 7

we know,
no. of protons = no. of electrons

therefore, no. of electrons = 7


so,no. of neutrons = 16 - 7
= 9
