The Atomic Mass number represents the total number of protons and neutrons in the nucleus of an atom. It does not include the number of electrons, which are found in the electron cloud surrounding the nucleus.

What letters are used to designate atomic number and mass number in isotopic notation of atoms?
The atomic number is denoted by the letter "Z" and the mass number is denoted by the letter "A" in isotopic notation of atoms.
How do you calculate the atomic weight of fluorine if the mass of 8.46.10 to the 24 atoms of fluorine is 266.889?
Atomic weight of fluorine = 6,022 141 78.1023 (Avogadro number) . 266,889 (the mass of atoms)/8,46.1024 (the number of atoms). The IUPAC 2005 atomic weight of fluorine is 18,998 403 2(5).
How many atoms of gold are in the bar?
The number of atoms in a bar of gold depends on the mass of the bar. To calculate the number of atoms, you would need to know the mass of the bar and the atomic mass of gold. You can use Avogadro's number to convert from grams to atoms.
What are an antonym atomic number?
The antonym of atomic number would be molecular mass. Atomic number refers to the number of protons in an atom's nucleus, while molecular mass refers to the mass of a molecule, which is the sum of the atomic masses of its atoms.
What is the atom with same atomic number but different mass number?
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 is the atoms mass number?
The Atomic Mass number tells how many protons and neutrons are in a nucleus.
How are atomic number and atomic mass alike?
Atomic number and atomic mass are not alike. Atomic number is the number of protons in the nuclei of the atoms of an element. Each element has a unique atomic number. Atomic mass is the combined masses of the protons, neutrons, and electrons of the atoms of an element. Individual isotopes of an element have specific mass numbers, which are the sum of the protons and neutrons in the nuclei of the atoms of the isotope.
How do you you work out the number of neutrons in an atom?
Atomic Mass minus atomic number
If an atoms atomic number is 8 and its atomic mass is sixteen how many nuetrons does it have?
16 - 8 = 8.
How is an nucleus symbolized with atomic number and mass number?
atoms and atomic structure
What determines the atomic number of a substance?
The atomic number is the number of protons in the nucleus of an atom, while the atomic mass is the total mass of the nucleus (both protons and neutrons)
What is the same as the atomic mass number of an element?
Atoms atomic number represents their number of protons.
What does Bohrs diagram represent?
it represents where the atoms, protons, Atomic Mass, atomic number, and electrons where they are located on the nucleus.
How many neutral atoms does atomic number 117 and atomic mass of 294 have?
An atom's atomic number corresponds to the number of protons in its nucleus, so an element with an atomic number of 117 has 117 protons. Since the atomic mass is 294, which accounts for the total number of protons and neutrons in the nucleus, we can subtract the atomic number from the atomic mass to find the number of neutrons: 294 (atomic mass) - 117 (atomic number) = 177 neutrons. Therefore, an atom of element 117 with an atomic mass of 294 would have 117 protons and 177 neutrons, resulting in 117 neutral atoms.
How are atomic mass and atomic number different?
Atomic number is the number of protons in the nuclei of the atoms of an element. Atomic number is unique to each element. Atomic Mass is the combined mass of the protons, neutrons, and electrons in an atom of an element.
What are the atomic number and atomic mass number of?
The atomic number of an element is the number of protons in the nuclei of its atoms. Mass number is the sum of protons and neutrons in the atomic nucleus of a particular isotope of an element.
What letters are used to designate atomic number and mass number in isotopic notation of atoms?
The atomic number is denoted by the letter "Z" and the mass number is denoted by the letter "A" in isotopic notation of atoms.
