Question

A neutral atom- X has 58 neutrons and atom- Y has 60 ncutrons. Which among the following will
have more electrons?
(A) Atom-X
(B) Atom-Y
(C) Both atom-X and Y will have same number of electrons
(D) Cannot be determined

Answer 1

Answer:

The number of electrons in an element with atomic number X and mass number Y will be X. It will be equal to the number of protons. The number of neutrons will be Y−X.

Number of electrons = number of protons = atomic number.

Number of neutrons = Mass number − atomic number.
