Question

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

based on the table, which atom has a charge of - 1?
1
2
3
4

Explanation:

Step1: Determine the charge formula

The charge of an atom is calculated as \(Charge = Number\ of\ protons - Number\ of\ electrons\).

Step2: Calculate the charge for each atom

• For atom 1:

\(Charge_1=9 - 9=0\)

• For atom 2:

\(Charge_2=9 - 8 = 1\)

• For atom 3:

\(Charge_3=9-10=-1\)

• For atom 4:

\(Charge_4=9 - 9=0\)

Answer:

3
