How many protons neutrons and electrons are in 27 AI 3-

Hey there!

27 tells us the sum of protons and neutrons is 27.

Al tells us we have 13 protons.

3- tells us that there are 3 more electrons than protons.

13 + n = 27

neutrons = 14

13 + 3 = 16 electrons

27Al3- has 13 protons, 14 neutrons, and 16 electrons.

Hope this helps!

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.

the answer is 1 i believe
