Question

-If an atom has 5 protons, 5 neutrons, and 3 electrons, what is the atom's charge?

A. +2
B. -2
C. 0
D. -3 ...?

Answer 1

Let's see the charge of each particle first:

- proton: charge +1

- neutron: charge 0

- electron: charge -1

We have 5 protons, 5 neutrons and 3 electrons, so the total charge of the atom is:

`Q=5 \cdot (+1) + 5 \cdot (0) + 3 \cdot (-1) =5+0-3=+2`

So, the correct answer is

A. +2

Answer 2

If an atom has 5 protons, 5 neutrons, and 3 electrons, the amom's charge is A. +2. charge=protons-electrons.
