Question

Explain FULLY what this symbol means/can tell you ( be sure to talk about numbers of protons, neutrons, and electrons.

Answer 1

Chlorine has 17 protons, 17 electrons and 18 neutrons. The atomic number is 17 and the mass number is 35.

Explanations:

The given element is Chlorine with an atomic number of 17 and a mass number of 35. The subscript serves as the atomic number while the superscript is the mass number.

The proton number is equal to the atomic number and electron number of a chlorine atom. Therefore;

Proton number = electron number = 17

For the neutron number

Neutron number is the difference between the mass number and the proton number;

Neutron number = Mass number - Proton number

Neutron number = 35 - 17 =18

Hence there are 18 neutron numbers in a chlorine atom
