Problem: Hydrogen has three isotopes (1H, 2H, and 3H), and chlorine has two isotopes (35Cl and 37Cl).Tell how many protons, neutrons, and electrons 1H35Cl contains.

FREE Expert Solution

We have to determine how many protons, neutrons, and electrons 1H35Cl contains.


Recall that the symbol of an element is written is this way:

 


Atomic number (Z): 

• represents the identity of the element

• reveals the number of protons

in a neutral element:

number of protons = number of electrons


Mass number (A)

• reveals the number of protons and neutrons

Mass number = Number of protons + Number of neutrons
