Look at the Atomic Mass of the element.
Round the atomic mass to the nearest whole number, and subtract the number of protons present in the nucleus (the atomic number).
The nucleus of the atom is made of protons and neutrons, so ideally, one can subtract the number of protons or neutrons to get the number of neutrons or protons.
So, Lithium would have 4 neutrons, Hydrogen would only have a proton, and Iron has 30 neutrons.
Of course, it depends, also, on the isotope of the element, which varies with the number of neutrons. So, carbon-14 would have 8 neutrons and 6 protons, while regular carbon would have 6 protons and 6 neutrons.

How many neutrons dose aluminum-24 have?
Looking at a periodic table, you see Al is number 13. It has 13 protons in the nucleus,so to have a total mass number of 24, it must have 11 nuetrons. Mass number = # protons + # nuetrons
How do you calculate the amount of protons or neutrons in an element?
well you look at the periodic table of elements. the atomic number equals the number of protons. Then subtract the number of protons from the atomic mass (both protons and nuetrons have atomic mass units of 1 and electrons equal 0). That will give you the number of nuetrons.
What is golds number in the periodic table?
Gold is number 79 on the periodic table
A gas with 8 protons and 8 nuetrons?
An atom with 8 protons will have an atomic number of 8. Checking the periodic table, we see this element is oxygen. The isotope of oxygen with 8 neutrons is 16O.
How is the periodic table is organized into columns called?
The elements arranged according to their atomic number in the table are called periodic table.
How do you find nuetrons in a periodic table?
To find the number of neutrons in an atom, round the mass number to the nearest whole number and subtract the atomic number.
What element on the periodic table has 53 protons 74 nuetrons?
Iodine

What does the atomic tell us?
it tells us the number on the Periodic Table and it also tells us how many protons and nuetrons and electrons are in the atom within the nuecles.

Where are the nuetrons found on the periodic table?
Neutrons are sub-atomic particles. The Periodic Table is an arrangement of the elements (atoms) made from these subatomic particles. Thus Neutrons by themselves have no place in the Periodic Table. However as all elements/atoms (except Hydrogen) contain some Neutrons, it is possible to find out how many using the information presented on the Periodic Table. The number of Neutrons present in an element/atom can be determined by subtracting the atomic number of an element/atom from its atomic mass.
What is the number of helium in the periodic table?
the number of helium in the periodic table is 2.
What is number 81 on the periodic table?
Number 81 on the periodic table is Thallium.
What is number 38 on the periodic table?
Number 38 on the periodic table is Strontium.
What is golds number in the periodic table?
Gold is number 79 on the periodic table
