What is the atomic mass unit of protons and neutrons?
atomic number or atomic mass
What is a synonym for atomic mass?
Unified atomic mass unit
What is atomic mass and the number of calcium?
Calcium has atomic number of 20, an atomic weight of 40.078 and an mass numbers of 40 - 48 inclusive in its isotopes. Atomic number is the count of protons in the nucleus. Mass number is the count of protons plus neutrons. The question refers to atomic mass rather than atomic weight. Atomic mass normally refers to the mass of a specific isotope of an element and is related to the mass number. Atomic weight ( or relative atomic mass as it is termed by IUPAC) the average mass of naturally occurring isotopes of an element. The relationship between mass number and atomic mass is defined in terms of the Atomic mass unit which is in simple terms 1/12 of the mass of a 12C atom. If you need to find out more about the relationship between mass number and and atomic mass you need to read the article "atomic mass unit" in wikipedia.
What do you use atomic mass units for?
The atomic mass unit is 1/12 from the mass of the isotope 12C.
How are the atomic mass unit and the atomic weight related?
The mass number is the total amount of protons and neutrons in an atom (the number of protons is the same as the number of electrons) The atomic number is the number of protons (or electrons) in an atom. To find out the number of neutrons in an atom, you need to take the atomic number from the mass number An atom is normally written like this: Mass number Ca Atomic number The Mass number can be written as (A) and the atomic number can be writtens as (Z)
Atomic mass represents the weight of an atoms protonsneutronsand electrons however the atomic mass is generally used to refer to just the number of protons and neytrons why?
Each electron weighs only about 0.0005 atomic mass unit, but protons and neutrons weigh 1 atomic mass unit each. Since there are the same number of protons, and usually even more neutrons, in an atom as there are protons, the weight of the electrons can be neglected in most chemical calculations.
Is a proton the least mass?
In an atom, there are 3 types of particles: protons, neutrons and electrons.Theoretically, protons and neutrons weight 1 Atomic Mass Unit. An electron weights 1/1836 of an Atomic Mass Unit. Therefore, in an atom, electrons weigh the least.
An atomic weight unit is the mass of one?
The atomic weight unit is 1/12 from the atomic mass of isotope 12C.

What unit is used to measure the mass of protons and neutrons?
Atomic mass is measured in atomic mass units (amu).

The protons has a mass of approx 1 you?
A proton has a mass of approx. 1 "atomic mass unit" or "amu".
Atomic mass is equal to what?
atomic mass unit is equal to one-twelfth of the mass of a carbon-12 atomic mass is equal to one-twelfth of the mass of a carbon-12Atomic Mass is equal to the number of protons and neutrons.
What do the atomic and mass number of an atom tell us?
The atomic weight (not mass) of a chemical element is the ratio between the average mass of the atoms of this element to 1/12 from the atomic mass of carbon-12.The atomic mass is a term applied only to specific isotopes; the unit is the same as above. Is a value denoting the total mass of all the protons, neutrons, and electrons in an isotope.The mass number is the sum of nucleons (protons and neutrons) in the atomic nucleus.
