Question

An atom has a mass number of 36 and an atomic number of 17.How may neutrons are in the atom? A.36 B. 17 C.19 D.53

Answer 1

Answer:

19neutron hope this help u plzz mark in brainlist

Explanation:

mass no is the sum of proton plus neutron p+n=36 p=17 so 36-17=19 neutron

Answer 2

Answer:

The number of neutrons present in the atom is equal to 19.

Therefore, the option (c) is correct.

Explanation:

• Atomic number of an atom is the number of protons or number of electrons present in an atom.

       $Atomic\; number = Number \;\;of\;\; protons = number \;\;of \;\;electrons$

• Mass number of an atom is the sum of number of protons and number of neutrons present in an atom.

        Mass number = Number of protons + number of neutrons

 We can also write the mass number as:

       Mass number =  Atomic number + number of neutrons

      Number of neutrons =  Mass number - Atomic number

We have given,

Mass number of atom = 36

Atomic number of atom = 17

Number of neutrons = 36-17 = 19

Therefore, the number of neutrons in the same atom is equal to 19.
