c) 35, 35, 80 d) 35, 45, 35

Answer 1

protons 35
Neutron 45
electrons 35
means option (D) 35,45,35

Answer 2

Hey there! Looks you missed a word

The complete question : The number of protons, neutrons and electrons present respectively in $^{80} Br_{35}$

So, In $^{A}X_{Z}$ ,

A is the mass number of the element X and Z is the atomic number.

We know that, Atomic number is the number of protons or number of electrons in the neutral gaseous atom.

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

We know that, number of neutrons = A - Z

Given, $^{80} Br_{35}$

Z = 35 , A = 80

Number of neutrons = 80 - 35 = 45

Number of electrons = Number of protons = Z = 35 ( As the atom is not having charge, and is neutral)

Therefore, The number of protons, neutrons and electrons respectively are 35 , 45 , 35 .

Required option is D.
