Answer 1

Answer:

If the atomic weight of an element is 23 times that of the lightest element and it has 11 protons, then it contains. 11 protons, 11 neutrons, 23 electrons.

Explanation:

Number of electron = number of proton

Hence,

number of electrons =11

and number of protons =11

The lightest element is hydrogen which has atomic weight 1.

Thus, an atomic weight of the element will be 23.

number of neutron = mass number - atomic number

=23−11=12
