If an atom of tin has a mass number of 118 and an atomic number of 50 how many neutrons are in its nucleus?

Protons = 4
Neutrons = 5
There are four protons, four electrons, and five neutrons.
You can find the number of protons by looking and the atomic number, and because this atom is not an ion (a charged atom), the number of protons and electrons are equal.
You can find the number of neutrons by subtracting the number of the protons from the Atomic Mass. In this case, 9 minus 4 equals 5 for the number of neutrons. Your atom is the element beryllium, and is specifically the one stable isotope of that element, 9Be.

Atomic No. is 50
This tells us that it has 50 Protons and 50 electrons. With a mass of 118.7
It has 118.7 - 50 = 68.7 neutrons. To a whole number it will be
69 neutrons.
From the Periodic Table this element is 'Tin' (Sn).

What is the number of neutrons in an atom affects the atomic what?
The number of neutrons in an atom can affect the atomic mass of an atom.
Define the term mass number?
Mass number is a value approximate to the number of protons (Atomic Number) plus the number of neutrons within an atom of the element considered. I say approximate as mass number takes into account the mass of the nucleus and not the actual number of protons and neutrons in the nucleus.
Where are protons neutrons and electrons located?
Protons, neutrons and electrons are located in the atom. The protons and neutrons are located in the atomic nucleus; the electrons are around the nucleus, arranged in shells.
What is the structure of the atom and the position of protons neutrons and electrons?
Protons and neutrons can be found in the centre of the atom in the nucleus. Electrons orbit round the nucleus in shells/orbits and are extremely small compared to the rest of the atom. Protons have a positive +1 charge and neutrons have no charge and are neutral. Electrons have a negative -1 charge. Protons and neutrons give the atom its mass. Each shell has a maximum number of electrons it can take. In the first shell it is 2. In all other shells (up to calcium) the maximum number is 8. An atom can gain or lose electrons, becoming what is known as an ion. An ion is nothing more than an electrically charged atom. Adding or removing electrons from an atom does not change which element it is, just its charge. The number of electrons equals the number of protons. The number of protons is the roton/atomic number. The number of neutrons can be found by subtracting the atomic mass from the atomic number (as the atomic mass it both the protons and neutrons combined.)
How many neutrons are in one atom?
The number of neutrons depends on the atom. In general, mass number = atomic number + number of neutrons.
Is atomic mass the amount of neutrons in the nucleus in the atom?
atomic mass = number of neutrons + number of protons.
Neutrons in the nucleus of an atom calculated?
Mass number minus atomic number = number of neutrons
What are the differences between the atomic number and the mass number of an atom?
atomic no is the no of protones in a nucleus while atomic mass is the sum of protons and neutrons in nucleus of an atom....
Mass number - atomic number?
This is the sum of all protons and neutrons in an atom. On the periodic table, it has the average for that element.
Nucleus of an atom characteristics?
Characteristic for an atomic nucleus are the number of protons and neutrons. Tha atomic nucleus is always positive.
Is the atomic number of an atom is equal to the number of protons or neutrons in the nucleus?
Protons
What does the atomic number of an atom made of?
An atomic nucleus contain protons and neutrons; protons and neutrons contain quarks and gluons.
Atomic mass is determined by the number of protons plus the number of?
Atomic mass is determined by the number of protons and neutrons in an atom's nucleus.
What is the difference of atomic number and atomic mass?
atomic number is the number of protons in the nucleus or electrons around the nucleus in an atom that is not ionized. atomic mass is the sum of the number of protons and the number of neutrons in the nucleus.
How is an atomic number similar to mass number?
The nucleus of an atom consists of protons and neutrons. The number of protons in a particular nucleus is its "atomic number". The total number of protons and neutrons in a particular nucleus is its "mass number".
What information does the mass number give?
the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
The atomic mass of silver is 107 and the atomic number of silver is 47 How many neutrons does a neutral atom of silver contain?
For any element, the atomic number is the number of protons in the nucleus. And for any element, the atomic mass is the number of protons plus the number of neutrons in the nucleus. For an element with the atomic number 47 and an atomic weight of 107, it will have 107 - 47 neutrons in its nucleus, or 60 neutrons in its nucleus. Whether or not an atom is a neutral atom or not makes no difference here.
