You subtract the atomic number from the mass number.
to get the number of neutrons subtract the atomic number from the mass number
the mass number is number of protons in an atom, plus the number of neutrons.
This is an atom of sulfur, which we know by the number of protons. And it's a neutral atom of sulfur, because the number of electrons equals the number of protons. Also, we know it's the most abundant isotope of sulfur because of the 16 neutrons. A link can be found below.electrons
If you add the number of protons to the number of neutrons in an atom, you have calculated that atom's atomic mass.
mass no - atomic no = number of neutrons in an atom.
The number of neutrons in an atom depends on the isotope. The most common sulfur isotope has 16. The average number of neutrons in an atom of sulfur is about 32.065.
The number of neutrons depends on the atom. In general, mass number = atomic number + number of neutrons.
The number of neutrons in an atom can affect the atomic mass of an atom.
The number of protons and neutrons in its' nucleus.
In a neutral atom, the number of electrons is equal to the number of protons of the nucleus.
protons and neutrons in the nucleus of an atom. Isotopes of an element have the same number of protons but different numbers of neutrons. The number of neutrons in an atom affects its stability and often determines its nuclear properties.
The total amount of protons and neutrons in an atom is its mass number.
they determine the atomic mass of the atom
By the sum of protons and neutrons we obtain the mass number of the atom which is written at the top of the atom periodic number. We can also obtain the mass number by adding the atomic number and the number of neutrons because the atomic number and the number of protons are same. You know that scientists have discovered some particles which are smaller than protons and neutrons and these are known as quartz.
nass number is the number of neutrons plus protons in the nucleus of an atom
The mass number of an atom is the number of protons plus the number of neutrons in its nucleus. So an atom with 15 protons and 10 neutrons would have a mass number of 15 + 10 = 25.
Of course, number of neutrons or neutron number !
Neutrons, like protons are considered to have a mass of about 1. To find the number of neutrons, subtract the atomic number from the atomic mass.
