How many protons and electrons does Neptunium have?

Answer 1

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

Answer 2

144 neutrons in neptunium 237; the number of neutrons is the difference between the Atomic Mass of an isotope and the atomic number of the element.

Answer 3

237Np has 93 protons and 144 neutrons.

For other isotopes see the link below.

Answer 4

Neptunium (the isotope 237Np) has 93 protons, 93 electrons and 144 neutrons.

Answer 5

Two of those things depend on the specific isotope and whether it's ionized or not; the one part of the question that can be definitively answered is that neptunium has 93 protons.

Answer 6

Neptunium's number of protons is equal to its atomic number. Checking a Periodic Table, we see that neptunium's atomic number is 93. Thus, it has 93 protons.

Answer 7

Neptunium has 93 electrons.

Answer 8

Neptunium has 93 protons.
