What is the net charge of an ion that consists of 10 electrons and 9 protons?
A
+1
B
0
C
-2
D
-1
Verified step by step guidance1
Identify the charges of the subatomic particles involved: protons have a charge of +1 each, and electrons have a charge of -1 each.
Calculate the total positive charge by multiplying the number of protons by their charge: $9 \times (+1) = +9$.
Calculate the total negative charge by multiplying the number of electrons by their charge: $10 \times (-1) = -10$.
Find the net charge of the ion by adding the total positive and total negative charges: $+9 + (-10) = -1$.
Interpret the result: since the net charge is -1, the ion has an overall charge of -1.
