The table below gives the numbers of protons, electrons, and neutrons in four atoms.

Atom Number of protons Number of neutrons Number of electrons
1 9 8 9
2 9 9 8
3 9 9 10
4 9 10 9

Based on the table, which atom has a charge of –1?
1
2
3
4

Answer:

Atom 3

Explanation:

The given data is as follows:

Atom number   Protons   Neutrons   Electrons

1                          9               8                9

2                         9               9                8

3                         9               9                10

4                         9               10               9

The charge on an atom is given by the relation:

Charge = number of protons - number of electrons

For atom 1: charge = 9 - 9 = 0

Atom 2 : charge = 9-8 = 1

Atom 3: charge = 9 -10 = -1

Atom 4 : charge = 9-9 = 0
