Question

questions 28 - 31 prompt: complete the tables by filling in the correct number of protons, neutrons and electrons. fill in the blank 1 point isotope nitrogen - 16 charge 2 - # protons type your answer... # neutrons type your answer... # electrons type your answer...

Explanation:

Step1: Determine proton number

Nitrogen has an atomic number of 7, so the number of protons is 7.

Step2: Calculate neutron number

The mass - number is 16. Neutrons = Mass - number - Protons. So, neutrons = 16 - 7=9.

Step3: Calculate electron number

The ion has a charge of 2-. Electrons = Protons+Charge. So, electrons = 7 + 2=9.

Answer:

protons: 7

neutrons: 9

electrons: 9
