Neon (Ne) has at. wt. of 20.183 and at. no. of 10.
We know that the number of Protons is equal to At. No. and the number of Electrons equals the number of Protons.
The number of Neutrons is the (At. Wt.) - (At. No.)
Thus, we know that Ne has 10 Protons, 10 Electrons and 10 Neutrons.

The atomic weight minus the number of protons = the atom's neutrons.
28. Atomic mass - Atomic # (same as the number of protons) = number of neutrons
There are 143 neutrons.
The Atomic Mass tells you how many Protons and Neutrons are in the atom. It is approximately the sum of the number of protons and neutrons found in the nucleus of an atom. Basically the weight of the neutrons and protons in one atom
The mass of an atom is found by adding the number of the protons and neutrons. So, a boron atom with 5 protons and 6 neutrons would have an atomic mass of 11.
Finding out how many neutrons are in a atom is easy. All you have to do is find the element's atomic number and atomic weight.
Finding out how many neutrons are in a atom is easy. All you have to do is find the element's atomic number and atomic weight.
The atomic weight minus the number of protons = the atom's neutrons.
28. Atomic mass - Atomic # (same as the number of protons) = number of neutrons
Number of neutrons = Atomic mass of an isotope - Atomic number of the element For the most important natural stable isotope of nitrogen - 14N - the number of neutrons is 7.
Protons and neutrons each have an atomic mass of 1 So, 38-15=23 Neutrons
There are 143 neutrons.
subtract the atomic number by the Atomic Mass, and that is the answer. if its a neutral atom, there are probably the same number neutrons as protons.
The number of neutrons depends on the atom. In general, mass number = atomic number + number of neutrons.
Uranium 238 has 92 protons and 146 neutrons.
The Atomic Mass tells you how many Protons and Neutrons are in the atom. It is approximately the sum of the number of protons and neutrons found in the nucleus of an atom. Basically the weight of the neutrons and protons in one atom
Atomic mass is protons + neutrons, and the atomic number (4) gives you the number of protons. Thus, this atom would have 5 neutrons.
