Which of the following gives the correct numbers of protons, neutrons, and electrons in a neutral atom of Sn?

A. 118 protons, 50 neutrons, 118 electrons
B. 118 protons, 118 neutrons, 50 electrons
C. 50 protons, 68 neutrons, 50 electrons
D. 68 protons, 68 neutrons, 50 electrons
E. 50 protons, 50 neutrons, 50 electrons

Answer :

The correct number of protons, neutrons, and electrons in a neutral atom of Sn is 50 protons, 68 neutrons, 50 electrons.

Neutral atom of Sn

Atomic number of Sn is 50 .

As we know

Atomic number = no. of protons = no. of electrons

then ,

Number of protons = 50

Number of electrons = 50

Now , atomic mass = no. of protons + no. of neutrons

Atomic mass of Sn is 118 u

Therefore , 118 = 50 + number of neutrons

Number of neutrons = 118 -50

Number of neutrons = 68

Hence, in a neutral atom of Sn , there are 50 protons , 68 neutrons , 50 electrons. option (c) is correct .
