Question

An atom consists of electrons, protons, and neutrons. Each electron has a charge of -1, each proton has a charge of +1, and each neutron has no charge. If 3 electrons are removed from each of 4 atoms, what is the combined net change to the charge of the 4 atoms? Complete the steps below to solve this problem and others like it.

Part A- Three electrons are removed from each of 4 atoms. Write an expression to represent the net change on the charge for the group of atoms.

Answer 1

Below

Explanation:

You removed 4 x 3 = 12 negative charges from the group of atoms

this will leave a +12 charge on the group of atoms ( the net change will be -12 )
