Answer:
The answer to your question is Protons = 36, Neutrons = 26, Electrons = 36
Explanation:
⁷⁰Se²⁻
The number of protons is equal to the atomic number, Selenium has an atomic number of 34. Then the number of protons = 34.
The number of neutrons = Mass number - number of protons
= 70 - 34
= 36
The number of electrons = number of protons + 2 because of the 2- next to the symbol of Selenium.
Number of electrons = 34 + 2
= 36
