Hey mate here's ur ans!!!!

Explanation:

1. Protons in Na+=Atomic No. of element= 11=Electrons in Na+

No. of neutrons = mass number - number of protons in element

= 22.990-11

=11.990

=12 (approximately)

2. A nitrate ion, [NO3]⁻, has 1*7 + 3*8 = 31 neutrons, which is also its number of protons. The number of protons and electrons are defined by the Atomic number. Nitrogen has an Atomic number of 7. This means that it has 7 protons and electrons.

3. calculate yhe total number of electrons and protons and nuetrons in NH4+and PO3- Answer: In N atom there are 7 electrons, 7 protons and 7 neutrons. In NH4+ there are 7+1+1+1+ 1 = 11 protons, 7 neutrons and 10 electrons since there is one electron less due to the positive charge.

Hope this helps u please mark me as brainliest also follow me please. . . . . . . . . .....
