Atomic Mass is the number of protons in an atom
mass number is the number of protons plus neutrons in an atom
What else can I help you with?
Is it true that The atomic mass is equal to the atomic number?
No, the atomic mass is not equal to the atomic number. The atomic number represents the number of protons in an atom's nucleus, while the atomic mass is the sum of protons and neutrons in the nucleus. The atomic mass can differ from the atomic number, especially due to the presence of neutrons.
Do Isotopes differ from each other only in the number of electrons contained?
Isotopes differ in the number of neutrons. All atoms are neutral - they always contain the same number of protons (positive) as electrons (negative). If they lose or gain electrons, they become ions. If they lose or gain protons (as in radioactive decay), they become a different element. An element is defined by its atomic number, which is the number of protons. Atoms may differ in their atomic mass. The difference is due to differing numbers of neutrons. The atomic mass on the periodic chart is the proportional average of all the naturally occurring isotopes. To determine how many neutrons in an atom, subtract the atomic number from the atomic mass.
What is the term for atoms of the same element that differ in their mass numbers?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
Isotopes of an element differ in their?
Isotopes must have the same atomic number, which is the number of protons. The atomic mass, which is the total number of protons and neutrons, varies for the different isotopes. so it should have different mass numbers..
What is the atomic mass number of krypton?
83.98 amu is the Atomic Mass, 36 is the atomic number.

What is the term for atoms of the same element that differ in their mass numbers?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
Why does the atomic number of an atom differ from the atomic mass?
Because the atomic number indicates the number of protons per nucleus while the mass number is the sum of the number of protons and the number of neutrons per nucleus, and all atoms except hydrogen-1 have neutrons in their nuclei.
Isotopes of an element differ in their?
Isotopes must have the same atomic number, which is the number of protons. The atomic mass, which is the total number of protons and neutrons, varies for the different isotopes. so it should have different mass numbers..
What are Atomic mass and atomic weight?
If you look critically, then you can say that mass is the amount of matter contained in a body and weight is the force with which an object is pulled by earth's gravitational force.But in this case, atomic mass is the mass of an atom (expressed as a dimensionless number = the number of protons + number of neutrons), while atomic weight is a weighted average of a sample of the substance. With different isotopes, it will differ from the atomic mass. See related link.
What is the atomic mass number of krypton?
83.98 amu is the Atomic Mass, 36 is the atomic number.
Does the atomic number equal the amount of neutrons?
no, the atomic number, for the most part, is how much protons and electrons there are. The number of neutrons is determined when you subtract the atomic number from the atomic mass. When chemical bonding happens however, the number of electrons and protons could differ.
How do the mass numbers and the atomic numbers of an element differ?
Atomic number equals the number of protons, the (atomic) mass number equals the sum of (the number of) protons and neutrons of the same element.The answer is: they're differing in the number of neutrons(Mathematically: Where A = p and M = p + n, the difference in A and M is n)
What are the atoms called then they have the same atomic number but different mass numbers?
They are called as isotopes in which mass number differ by emmision of radiation
What is the difference between the atomic number mass number and atomic mass?
We can find Atomic Mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
What do you do with an atomic number and an atomic mass?
The atomic number is the number of a chemical element in the periodic table of Mendeleev; the atomic number is equal to the number of protons and electrons. The atomic mass is the mass of an atom expressed in relative atomic mass units.
