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.
How is the atomic mass determined?
Atomic Mass is the number of protons in an atom plus the number of neutrons in the same atom.
How relative atomic mass of an atom can be determined?
The relative atomic mass of an atom can be determined by averaging the masses of its isotopes based on their abundance in nature. This value is reported relative to the mass of a carbon-12 atom, which has been assigned a relative atomic mass of exactly 12.ø
What is the atomic number of an atom determained by the number of what?
The atomic number of an atom is determined by the number of protons it has.
Why is the atomic mass scale also called the relative atomic mass scale?
All atomic masses are determined by comparing them to the mass of an atom of carbon12. One atomic mass unit equals one twelfth the mass of an atom of carbon12. That's why its called relativeatomic mass.

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.
How were the atomic number and the atomic masses of the elements determined?
Atomic masses are determined by mass spectrometry. The atomic number is identic with the number of protons in the atom - depends on position in the periodic table.
How is the atomic mass determined?
Atomic Mass is the number of protons in an atom plus the number of neutrons in the same atom.

What is the atomic number of an atom determained by the number of what?
The atomic number of an atom is determined by the number of protons it has.
The atomic number is determined by?
The atomic mass is the can be determined by the number of protons in an atom. Remember that a proton has an atomic mas number of 1 AMU (atomic mass unit). (The total mass of an atom is the protons, neutrons and electrons combined.)
What is the atomic mass of an atom?
The atomic mass of an atom is the combined mass of the protons and neutrons in the nucleus.
What atom is standard for atomic masses?
Carbon (12).
What is the mass of an atom mainly determined by?
The sum of masses of protons, neutrons and electrons.
How is the mass of 1 mole of an element determined?
The mass of 1 mole of an element is determined by summing the atomic masses of each atom in the element's chemical formula. This value is typically expressed in grams per mole, referred to as the molar mass. It is based on the relative atomic masses of the isotopes that make up the element.
How can an atom's protons be determined?
By the atomic mass
What is the mass of an atom found by?
The mass of an atom is primarily determined by the combined masses of its protons, neutrons, and electrons. Protons and neutrons contribute most of the mass since electrons have negligible mass. The exact mass of an atom can be found by adding up the masses of its protons, neutrons, and electrons.
