Question

The element chlorine has atomic no.17 and atomic mass 35. Calculate the no. of protons, neutrons and electrons. ​

Answer 1

Answer:

Protons = 17 Neutrons = 18 Electrons = 17

Explanation:

The number of protons and electrons are the the same number as the atomic number.

To get the number of neutrons, subtract the number of protons from the mass number.

35-17=18

Answer 2

Answer:

Protons: 17

Neutrons: 18

Electrons: 17

Explanation:

To find the number of protons, you simply have to find the atomic number of the element.

To find the number of protons you have to subtract the atomic number from the atomic mass

To find electrons to add or subtract the charge that the element has. (In this case, it has no charge)
