What is the total charge of the nucleus of a nitrogen atom

The total charge on nucleus =  1.12 x10 ⁻¹⁸C

Explanation:

Atomic Structure: Atom is the smallest particle of an element.

it consists of Two portion i.e. orbitals and Nucleus

The electron have -ve charge

proton have +ve charge

neutrons have no charge at all

So

Atomic Number : The number of electrons or proton (number of electrons equal to the number of proton in an atom of element)

Atomic Mass: atomic mass is the number of proton plus neutron in the nucleus.

Now keeping in mind

Nitrogen have Atomic number 7 and atomic mass is 14

so it have 7 electron in its orbital

So for the total charge on the nucleus with electrons in atom is zero

but if we ignore the electrons in the atom

then we can calculate the charge on nitrogen atom is as follow:

value of charge on proton = 1.602×10 ⁻¹⁹ C

number of proton in Nitrogen nucleus = +7

so the total charge on nucleus = +7 x 1.602×10 ⁻¹⁹ C = 1.12 x10 ⁻¹⁸C

total charge on nucleus = 1.12 x10 ⁻¹⁸C
