The Atomic Mass is approximately the sum of the number of protons and neutrons.

What is Carbon-12 atomic mass?
12. The number 12 refers to the atomic mass. More precisely, to the sum of neutrons + protons; but this is usually close to the atomic mass. In the case of carbon-12, it is exact, by definition.
What is the relationship btw atomic mass and atomic 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.
Why is the atomic mass number not a whole 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 number is 174 in platinum?
The number 174 in platinum refers to mass number or A. This is applicable to atomic nuclei of Pt 174 isotope.
What is the atomic mass number of iodine?
The atomic mass number of iodine is 17.8923
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 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.
The atomic number refers to the number of what in an atom?
Z, or the atomic number, represents the number of protons in a element as opposed to A, which is the mass number, the number of protons and neutrons.
What is the difference between atomic mass and atomic number?
Atomic mass refers to the total mass of an atom, including the mass of protons, neutrons, and electrons. Atomic number, on the other hand, represents the number of protons in the nucleus of an atom, which determines its chemical properties and place on the periodic table.
An explination of what mass number and atomic number are?
The atomic number refers to the number of protons in the element. And since the number of protons = number of electrons, the atomic number is also the number of electrons in the element. The mass number of an element refers to the number of neutrons and protons in the element. &since electrons are negligible in mass, the number of neutrons can be found out by subtracting the atomic number from the mass number. Take for example, oxygen. Oxygen has an atomic number of 8 and a mass number of 16. Hence, from the atomic number it can be derived that it has: 8 electrons 8 protons While from the mass number, it can be derive that it has: 16-8 = 8 neutrons
Is mass number the same as atomic number?
No. Atomic number refers to the number of protons present in the nucleus of the atom whereas mass number refers to the sum of the number of protons and neutrons in the nucleus. For example, the isotope lithium-6 has an atomic number of 3 (for 3 protons) and a mass number of 6 (for 3 protons and 3 neutrons).
What is the difference between atomic number and atomic mass?
Atomic number refers to the number of protons in an atom's nucleus, which determines the element's identity. Atomic mass is the average mass of an atom of that element, taking into account the mass of protons, neutrons, and electrons. Atomic mass is measured in atomic mass units (amu).
What the distinction between atomic mass and atomic number?
the number of positive charges or protons in the nucleus of an atom of a given element, and therefore also the number of electrons normally surrounding the nucleus. (atomic number) The mass of a given atom or molecule, expressed in atomic mass units. (atomic mass)
What is the difference between atomic mass and mass number?
Atomic mass refers to the average mass of an atom of an element, taking into account the masses of its isotopes and their relative abundance. Mass number, on the other hand, is the total number of protons and neutrons in the nucleus of an atom. Atomic mass is measured in atomic mass units (amu), while mass number is a whole number without units.
If atomic mass of 16 and atomic number of 8 this means the number of neutrons in this type of oxygen is?
The number of neutrons in an atom can be calculated by subtracting the atomic number from the atomic mass. In this case, an atomic mass of 16 and atomic number of 8 for oxygen means there are 8 neutrons (16 - 8 = 8).
Is atomic mass and molar mass similar and mass number of particles the same?
Atomic mass and molar mass are similar concepts but not the same. Atomic mass refers to the average mass of an atom of an element, while molar mass is the mass of one mole of a substance. The mass number of particles can be the same in certain cases, such as isotopes of the same element which have the same number of protons and different numbers of neutrons.
Which of the following determines the identity of an element atomic number mass number atomic mass or overall change?
Atomic number determines the identity of an element. It represents the number of protons in an atom's nucleus, which is unique to each element. Mass number refers to the total number of protons and neutrons in an atom's nucleus, while atomic mass is the average mass of an element's isotopes. Overall charge is determined by the number of protons and electrons in an atom, but it does not uniquely identify the element.
