The atomic mass of an element is equal to the number of protons.
No, the atomic mass is not equal to the atomic number. The atomic number represents the number of protons in an atom's nucleus, while the atomic mass is the sum of protons and neutrons in the nucleus. The atomic mass can differ from the atomic number, especially due to the presence of neutrons.
The atomic mass of an element is equal to the sum of the number of protons and neutrons in its nucleus. It is not directly related to the atomic number, which represents the number of protons in an atom.
The atomic mass of an atom is the total mass of protons, neutrons, and electrons in the atom, measured in atomic mass units (amu). It is approximately equal to the sum of the number of protons and neutrons in the atom's nucleus.
The unified atomic mass unit (u) is equal to 1/12 of the mass of a carbon-12 atom. This corresponds to a mass of approximately 1.66 x 10^-27 kg. The unified atomic mass unit is commonly used in chemistry and physics to express atomic and molecular weights on a scale relative to the mass of a carbon-12 atom.
neutrons in an atom's nucleus. It is measured in atomic mass units (amu) and provides the total mass of an atom. The atomic mass is approximately equal to the sum of the protons and neutrons in the nucleus, as the mass of electrons is negligible.
atomic mass is contributed mainly by protons and neutrons. it is the mass of an atom. atomic number on the other hand is contributed by protons and is equal to the number of protons in the atom
protons + electrons= atomic mass NUMBER, not the atomic mass.
number of protons = atomic mass
The atomic number is equal to either the number of electrons or the protons of a particular atom. The atomic mass in a.m.u. is equal to the sum of protons and neutrons in an atom.
No, the atomic mass is not equal to the atomic number. The atomic number represents the number of protons in an atom's nucleus, while the atomic mass is the sum of protons and neutrons in the nucleus. The atomic mass can differ from the atomic number, especially due to the presence of neutrons.
It is equal to the difference between atomic number and Atomic Mass number. A+
If you add the number of protons to the number of neutrons in an atom, you have calculated that atom's atomic mass.
The atomic mass of an element is equal to the sum of the number of protons and neutrons in its nucleus. It is not directly related to the atomic number, which represents the number of protons in an atom.
Only if the atom is hydrogen-1! The mass number of the atom is equal to the sum of the numbers of protons, which is the same as the atomic number, plus the number of neutrons. The only non-radioactive atom without neutrons is hydrogen-1.
The atomic mass of an atom is the total mass of protons, neutrons, and electrons in the atom, measured in atomic mass units (amu). It is approximately equal to the sum of the number of protons and neutrons in the atom's nucleus.
the total mass of its protons, neutrons, and electrons.
