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)
What is a synonym for atomic mass?
Unified atomic mass unit
What is the atomic mass unit of protons and neutrons?
The atomic mass unit of protons and neutrons is approximately 1.67 x 10^-27 kg. This unit is used to express the mass of subatomic particles in atomic physics.
Atomic mass of an atom is determined by the weight of?
The atomic mass of an atom is determined by the total number of protons and neutrons in its nucleus. Protons and neutrons contribute to the majority of an atom's mass, electrons have negligible mass in comparison. The atomic mass unit (amu) is used to express atomic mass, with 1 amu approximately equal to the mass of a proton or neutron.
Atomic mass of an atom is determined by the combined masses of?
Atomic mass of an atom is determined by the combined masses of its protons, neutrons, and electrons. Protons and neutrons contribute most of the mass, as they are much heavier than electrons. The atomic mass is usually given in atomic mass units, where 1 unit is defined as 1/12 the mass of a carbon-12 atom.
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 units. A proton has a mass of 1 atomic unit, and so does a neutron. the mass of an electron is very small, and almost negligible
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.
How do you calculate the atomic mas based on the number of protons and neutrons of an atom?
To calculate the atomic mass of an atom, you would add the number of protons and neutrons together. Protons and neutrons each have a mass of approximately 1 atomic mass unit (amu). The sum of the protons and neutrons will give you the atomic mass of the atom in atomic mass units.
What is Atomic mass units of an atom that contains 8 protons 9 neutrons 8 electrons?
The atomic mass unit of an atom is the sum of the protons and neutrons in its nucleus. In this case, with 8 protons and 9 neutrons, the total atomic mass unit of the atom would be 17. The number of electrons does not significantly affect the atomic mass unit of an atom.
