Question

number of protons and neutrons in Al3+ ion
​

Answer 1

Answer:

13 neutrons and 13 protons

Answer 2

The number of protons and neutrons in $Al^{+3}$ is 13 and 14.

• The number of protons+neutrons =mass number.
• Number of electrons is equal to number of protons.
• Al have mass number 27.
• It have electron 13 so number of protons will also 13. For $Al^{+3}$ the number of electrons are (13-3=10) but this does not affect the number of protons.
• Number of neutrons is (27-13=14).
