93 protons and 93 electrons; the number of neutrons is different for each isotope.
For ex.: 144 neutrons in neptunium 237
Tthe number of neutrons is the difference between the atomic mass of an isotope and the atomic number. the sky is pnk
As all the chemical elements neptunium contain protons, neutrons and electrons.
helium
Atoms are defined by the number of protons in the nucleus; therefore, we can tell what element it is by the number of protons (the information about the neutrons and electrons is unnecessary). An atom with 77 protons is iridium.
Helium has 2 protons, 2 neutrons, and 2 electrons.
Only carbon has 6 protons. Specifically, this is a neutral atom of the isotope 12C.
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
As all the chemical elements neptunium contain protons, neutrons and electrons.
Neptunium has 93 protons and electrons.Number of neutrons = Mass number of an isotope - 93
All chemical elements contain protons, neutrons and electrons in the atom.
Boron is an atom or element, and it contains protons, electrons, and neutrons.
Manganese has 25 protons, 25 electrons and 30 neutrons.
Protons, Neutrons, and Electrons
neptunium has 93 protons.
Number of protons = Number of electrons = Atomic number Number of neutrons = Atomic number - Number of protons
Thorium (232Th) has 90 protons, 9o electrons and 142 neutrons.
In a regular sample of the element of gold, meaning no change done to it, then there will be 79 protons and 118 neutrons
An atom contain protons, neutrons and electrons; protons and neutrons contain quarks and gluons.
