Question

You will need to obtain a periodic table. Given the atomic notation of 64/30 Zn, indicate the number of protons, neutrons and electrons respectively, in an atom of zinc.

Answer 1

In an atom of zinc, there are 30 protons, 34 neutrons, and 30 electrons.

Step-by-step explanation:

In the atomic notation 64/30 Zn, the atomic number represents the number of protons in an atom. In this case, the atomic number of zinc (Zn) is 30, so it has 30 protons. The mass number represents the total number of protons and neutrons in the nucleus. The mass number of zinc-64 (64/30 Zn) is 64, so it has 34 neutrons (64 - 30).

Since atoms are electrically neutral, the number of protons and electrons are equal in an atom. So, an atom of zinc-64 would also have 30 electrons.
