An oxygen atom contains 8 protons and 8 neutrons in its center, and 8 electrons in various levels outside its center.
Each element has a different number of protons and neutrons. So it changes for each element.
Um, the element calcium? Protons, neutrons, electrons..
As all the other chemical elements bohrium contain protons, neutrons and electrons.
An atomic nucleus contain protons and neutrons; protons and neutrons contain quarks and gluons.
Isotopes of a chemical element have a similar number of protons but a different number of neutrons.
An atom contain protons, neutrons and electrons; protons and neutrons contain quarks and gluons.
An atom contain protons, neutrons and electrons; protons and neutrons contain quarks and gluons.
Each element has a different number of protons and neutrons. So it changes for each element.
An element is made from atoms. Atoms contain protons, neutrons and electrons. Protons and neutrons contain quarks and gluons.
Um, the element calcium? Protons, neutrons, electrons..
The element that has 8 protons and 8 neutrons is oxygen.
Every element has a specific amount of protons and neutrons in its nuclues. If an atom has more protons and neutrons than another element, it is heavier.
The isotope helium-3 contain 2 protons and 1 neutron. The isotope helium-4 contain 2 protons and 2 neutrons.
Uranium being element 92, it has 92 protons. If not ionized it also has 92 electrons. U-241 has 241 protons and neutrons together, so it would have 149 neutrons.
Sum of protons and neutrons is the Mass number of the element. The number of protons is equal to the number of electrons. Neutrons and protons are sub atomic particles.
The nucleus of an atom contain protons and neutrons; protons and neutrons contain quarks and gluons.
As all the other chemical elements bohrium contain protons, neutrons and electrons.
