Solution

Dear Student,

An atom of an element is represented by ¹⁹ ₉X.

Atomic number of element = 9
Number of electron = 9
Number of proton = 9
Atomic mass = 19
Atomic mass = Number of neutron + number of proton
19 = Number of neutron + 9
Number of neutron = 10

Regards

An atom of an element is represented by ¹⁹₉X. How many electrons and neutrons are present in this atom?

Dear Student,

An atom of an element is represented by ¹⁹ ₉X.

Atomic number of element = 9
Number of electron = 9
Number of proton = 9
Atomic mass = 19
Atomic mass = Number of neutron + number of proton
19 = Number of neutron + 9
Number of neutron = 10
