The average number of neutrons that a specific element has is equivilent to the element's Atomic Mass minus the that elements atomic number. For example Helium has 2 neutrons because its atomic mass (4) minus the atomic number (2) is 2.

An atom does not have to have equal numbers of?
The mass number can differ within the same element becasue the number of neutrons can change.
The mass number of an elements is equal to?
the total number of protons and neutrons in the nucleus.
The mass number of an element is equal to what of an element?
The sum of the number of protons and the number of nuetrons.
Do atoms have equal electrons and protons?
Not all atoms have an equal number of protons and neutrons. They can, but they don't have to. Helium, for example, has two of each, but carbon (always with 6 protons) can have 6, 7, or even 8 neutrons. The more neutrons, the more likely it is to be radioactive. The number of protons and neutrons gives the atomic weight of an atom. All of the various amounts of neutrons that an element can have are called isotopes of that element.
Why is the mass number bigger than the atomic number?
The atomic number of an element is the number of protonsin its atom's nucleus. The mass number of an element is the number of nucleons (protons or neutrons) in its atom's nucleus. Except in the case of hydrogen, which has no neutrons, the mass number will always be higher.
Is the atomic number of an atom equal to the number of protons or neutrons or electrons in the nucleus?
No, atomic number equals the number of protons.The number of neutrons is NOT specific to an element, and various atoms of the same element can have different numbers of neutrons - these are called isotopes.
What is the sum of protons and neutrons known as an element?
Sum of protons and neutrons is the Mass number of the element. The number of protons is equal to the number of electrons. Neutrons and protons are sub atomic particles.
What is an element that is equal to its number of protons and neutrons?
A stable one.
An atom does not have to have equal numbers of?
The mass number can differ within the same element becasue the number of neutrons can change.
How is the mass number related to the number of protons and neutrons and atoms has?
The mass number of an element is equal to the number of protons plus the number of neutrons.
The mass number of an elements is equal to?
the total number of protons and neutrons in the nucleus.
Is the atomic weight of an element is equal to the number of protons minus the number of neutrons?
Atomic weight of an element is the number of protons plus neutrons in the nucleus, atomic number is the number of protons only.
Can atomic weight minus the number of neutrons equal the number of isotopes an element has?
It is not correct.
What number identify an element?
The atomic number of an element is equal to the number of protons in the nucleus of that element; it will identify the element. The number of neutrons of a given element may be different as the element may have a number of isotopes.
The mass number of an element is equal to what of an element?
The sum of the number of protons and the number of nuetrons.
What does the atomic number of an element say about the number of particles in atoms of that element?
The atomic number is equal to the number of protons and neutrons in a neutral atom.
Do atoms have equal electrons and protons?
Not all atoms have an equal number of protons and neutrons. They can, but they don't have to. Helium, for example, has two of each, but carbon (always with 6 protons) can have 6, 7, or even 8 neutrons. The more neutrons, the more likely it is to be radioactive. The number of protons and neutrons gives the atomic weight of an atom. All of the various amounts of neutrons that an element can have are called isotopes of that element.
