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.
Number of protons + Number of neutrons = Mass number(number of nucleons)
Isotopes have the same amount of protons but a different amount of neutrons.
The mass number is the amount of protons and neutrons in an element. The atomic number is equal to the amount of protons. Therefore to get the number of protons from the given information, you would subtract 37 from 72 which gives you 35 protons aka its atomic number!
No, the atomic number refers to the protons of an atom, and for the most part the electrons. The atomic mass refers to the neutrons of an element in a way; the atomic mass consists of protons and neutrons, so if you subtract the amount of protons from the atomic mass, you get the amount of neutrons. For example oxygen has an average atomic mass of 16.01 and has 8 protons, so 16.01 atomic mass-8 protons=8.01 average neutrons. Now this is just for the average amount of neutrons, which is changed by isotopes (atoms with different amounts of neutrons).
The atomic mass of the element with eight protons and nine neutrons is 17 atomic mass units. This is calculated by adding the number of protons and neutrons together, as electrons contribute negligible mass to the overall atomic mass.
Number of protons + Number of neutrons = Mass number(number of nucleons)
Isotopes have the same amount of protons but a different amount of neutrons.
The Atom consists of a certain amount of electrons, protons and usually neutrons. The amount of each of these sub-atomic particles is what makes an element that specific element. Actually, it is only the protons. The number of neutrons and/or electrons can vary, and it is still the same element. The one thing that makes an element that specific element is only the number of protons.
The mass number is the amount of protons and neutrons in an element. The atomic number is equal to the amount of protons. Therefore to get the number of protons from the given information, you would subtract 37 from 72 which gives you 35 protons aka its atomic number!
them mass number of an element is the total amount of nuetrons and protons in the element , and the atomic number is the amount of protons ( and electrons) in the element simply subtract the atomic number from the mass number and you'll have the number of neutrons in the element hope this helped x
Protons and Neutrons are found in the Nucleus of the Atom. An atom's atomic number corresponds to the amount of protons (differnt amount of protons=different element). There are usually the same amount of Neutrons and Protons, but in some cases theere are more Neutrons (these are called different isotopes).
No, the atomic number refers to the protons of an atom, and for the most part the electrons. The atomic mass refers to the neutrons of an element in a way; the atomic mass consists of protons and neutrons, so if you subtract the amount of protons from the atomic mass, you get the amount of neutrons.

The atomic mass of the element with eight protons and nine neutrons is 17 atomic mass units. This is calculated by adding the number of protons and neutrons together, as electrons contribute negligible mass to the overall atomic mass.
An atom is a nucleus of protons and neutrons with electrons orbiting around. An element is an atom with a specific amount of protons, neutrons, and electrons. A molecule is a bunch of atoms stuck together.
The atom is the smallest particle of an element that retains it's characteristics. Sub-atomic particles such as protons, neutrons and electrons form the atom and it is the amount of each of these sub-atomic particles that make the element that element.
The number protons in an atom is called the atomic number (it is this number that tells us which element the atom is). The number of neutrons in an atom can change, but the term for the amount of neutrons is called an isotope. The number of protons and neutrons added together is called the atomic mass.
The number of protons in Chlorine is relative to its atomic number of 17. The amount of protons will not change, or will become a different element. The 37 refers to the amount of nucleons in the element. The total nucleons is calculated by adding the amount of protons and neutrons, so if we know there are 17 protons, 37-17= 20 neutrons. There are 17 protons and 20 neutrons in Cl-37.
