Neptunium is a chemical element with the symbol Npand atomic number 93.
So it has 93 protons and the neutral atom has also 93 electrons.
It is a radioactive metallic element, the first transuranic element and it belongs to the actinide series. Its most stable isotope is 237Np, with 237-93=144 neutrons
The number of valence electrons in neptunium, which has an atomic number of 93, can be determined by looking at its electron configuration. Neptunium has a configuration of [Rn] 5f^4 6d^1 7s^2, so it has 3 valence electrons.

Neptunium has 93 protons and electrons.Number of neutrons = Mass number of an isotope - 93
neptunium has 93 protons.
As all the chemical elements neptunium contain protons, neutrons and electrons.
Neptunium has 93 protons.
All chemical elements contain protons, neutrons and electrons in the atom.
All the isotopes of neptunium has 93 protons.
All the isotopes of neptunium has 93 protons.
Neptunium has two valence electrons.
I assume you mean neptunium, 93.
The number of valence electrons in neptunium, which has an atomic number of 93, can be determined by looking at its electron configuration. Neptunium has a configuration of [Rn] 5f^4 6d^1 7s^2, so it has 3 valence electrons.
Protons=electrons=33
15 electrons and 15 protons
