The nucleus of the atom of an element contains 17 protons and 18 neutrons. Calculate the atomic number and mass number of the element and represent them along with the symbol of the element.

Text Solution

Verified by Experts

Atomic number (Z)=Number of protons = 17 Mass number (A) = No. of protons + No. of neutrons = 17 + 18 = 35 Element with atomic number 17 is chlorine. Hence, we represent it as `""_(17)^(35 )CI`.
