Does nitrogen have 10 neutrons?
However, the atomic mass number, A, changes. However, not all nitrogen nuclei have 8 neutrons in a nucleus. They can have 5, 6, 7, 8, 9, 10 or 11 neutrons. We call these different isotopes of nitrogen.
Does sodium have 10 neutrons?
The mass number of an element tells us the number of protons AND neutrons in an atom (the two particles that have a measurable mass). Sodium has a mass number of 23amu. Since sodium has 11 protons, the number of neutrons must be 23 – 11 = 12 neutrons.
What 2 elements has an atom and 10 neutrons?
All beryllium atoms have 5 neutrons in the nucleus and all fluorine atoms have 10 neutrons.
How many neutrons does carbon 12 have?
6 neutrons
Carbon occurs naturally in three isotopes: carbon 12, which has 6 neutrons (plus 6 protons equals 12), carbon 13, which has 7 neutrons, and carbon 14, which has 8 neutrons. Every element has its own number of isotopes. The addition of even one neutron can dramatically change an isotope’s properties.
What is the neutron of oxygen?
Oxygen-16

What particle contains 10 electrons 11 protons and 12 neutrons?
The particle that contains 10 electrons, 11 protons and 12 neutrons is a positively-charged sodium ion (Na+).
What two elements have 10 neutrons in nucleus?
Does neon have 10 neutrons?
Neon is an atom with atomic number ten. Its atomic weight is 20.179 which cause it to have ten neutrons and ten protons in its nucleus and ten electrons outside. Neon has an atomic number of 10 and a mass number of 20.1797.
What element is the only one without any neutrons?
There is only one stable atom that does not have neutrons. It is an isotope of the element hydrogen called protium. Protium, which contains a single proton and a single electron, is the simplest atom. All other stable atoms contain some number of neutrons.
What element has 12 neutrons and 11 electrons?
The element sodium has 12 neutrons, 11 electrons and 11 protons. The number of electrons and protons come from the element’s atomic number, which is same 11. The number of neutrons can be found by subtraction of the atomic number from sodium’s atomic mass of twenty three. Click to see full answer
Which element has the most protons?
The heaviest element in nature is uranium, which has 92 protons. But heavier elements-which have more protons in their nucleus-can be created through nuclear fusion. (Related: Learn how to make an element .)
Which do elements have more neutrons than protons?
The stable isotopes of the heavier element have a great surplus of neutrons compared to the number of protons. For example the stable isotope of uranium, U_238, has 92 protons and 146 neutrons, nearly a (3/2) to 1 ratio. This may be a matter of that combination involves a lower energy than other combinations of the same number of nucleons.
