How many neutrons are in a silicon atom with an atomic mass of 28?

There are 14 neutrons.
Atomic Mass is the total amount of neutrons and protons that are contained within an atom's nucleus.
So, if you are given the Atomic Mass, proton count, neutron count, or electron count, then you can find out the approximate any of those values algebraically.
And remember that atomic mass has decimals since it is the average of all the element's isotopes.

How many protons and neutrons and electrons are there in a neutral atom of silicon-28?
A neutral atom of Silicon-27 contains 14 protons, just like any atom of Silicon (Si). Silicon has an atomic number of 14. The most abundant form of Si is Silicon-28, which has 14 neutrons. Silicon-27 has 13 neutrons.
How do you calculate how many neutrons there are in a atom?
The atomic weight minus the number of protons = the atom's neutrons.
If the atomic mass of an atom is 48 and the atom contains 20 protons how many neutrons does the atom contain?
28. Atomic mass - Atomic # (same as the number of protons) = number of neutrons
How many neutrons are in a Uranium atom with a mass of 235 and atomic?
There are 143 neutrons.
How many electrons does silicon-28 have?
Silicon atoms, atomic number 14, have 14 protons in the nucleus. The neutral atom then has 14 electrons. Silicon 28 the most common isotope of silicon has 14 neutrons in the nucleus giving a mass number of 28. The atomic mass of silicon 28 relative to carbon12=12. is 27.9769265325(19)

How many protons electrons and neutrons does Si-29 has?
Silicon-29 has 14 protons (atomic number), 14 electrons if the atom is neutral, and 15 neutrons (mass number - atomic number).
How do you figures out how many neutrons are in an an atom?
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.

If the atomic mass of an atom is 38 and the atom contains 15 protons how many neutrons does the atom contain?
Protons and neutrons each have an atomic mass of 1 So, 38-15=23 Neutrons
How many neutrons are in one atom in fluorine?
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.
How many neutrons are in one atom?
The number of neutrons depends on the atom. In general, mass number = atomic number + number of neutrons.
How many electrons does silicon-28 have?
Silicon atoms, atomic number 14, have 14 protons in the nucleus. The neutral atom then has 14 electrons. Silicon 28 the most common isotope of silicon has 14 neutrons in the nucleus giving a mass number of 28. The atomic mass of silicon 28 relative to carbon12=12. is 27.9769265325(19)
