Question

An atom has 26 electrons and its atomic weight is 56 the number of neutrons in the nucleus of an atom will be

Answer 1

the number of neutrons is equal to A-Z
56-26=30

Answer 2

Answer:

The correct answer to this question is 30.

Explanation:

Given - An atom has 26 electrons and its atomic weight is 56 the number of neutrons in the nucleus of an atom.

To Find - Write an atom that has 26 electrons and its atomic weight is 56 the number of neutrons in the nucleus of an atom.

The total number of neutrons in the atom is equal to 30 when the number of electrons is 26 and the mass number is 56.

$_{26} X^{56}$

A = P + N = Z + N = E + N

N = A − E = 56 − 26 = 30

The number of neutrons in the nucleus of the atom will be 30
