Question

question 23 (1 point)
what is the number of electrons in an al+3 ion?
o a 13
o b 3
o c 10
o d 6

Explanation:

Step1: Determine the atomic number of Al

The atomic number of Al (aluminum) is 13. This means a neutral Al atom has 13 electrons.

Step2: Consider the charge of the ion

The ion is \(Al^{+3}\). A positive charge of +3 indicates that the ion has lost 3 electrons.

Step3: Calculate the number of electrons

We subtract the number of lost electrons from the number of electrons in the neutral atom. So, \(13 - 3=10\).
