Question

A science webinar has been arranged for small children to teach them the basic
concepts of atoms. An atom consists of charged particles called protons and electrons.
Each proton has a charge of +1 and each electron has a charge of –1. Number of
electrons is always equal to the number of protons in an atom.
1)What will be the charge in an atom, if it loses a proton?
2)If an atom gains two electrons and loses one proton, then what will be the net
charge?

Answer 1

Answer:

1) -1

2) -3

Step-by-step explanation:

the overall charge of the atom is 0, with each electron being -1 and each proton being +1 charge.

1) in case a proton is removed, the charge of the atom will be-

0 - (+1) = 0 - 1 = -1

2) in case it receives 2 electrons and loses a proton-

0 + (-2) - (+1) = 0 - 2 - 1 = -3
