The atomic mass of an element is equal to the number of protons.
What else can I help you with?
Is it true that The atomic mass is equal to the atomic number?
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.
What number is the atomic mass equal to?
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.
What is the atomic mass of a 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.
What is the unified atomic mass unit equal to?
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.
Atomic mass is determined by the number of protons plus the number of?
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.
Why doest the atomic number equal the atomic mass?
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
The atomic mass of an atom is equal to the sum of numbers of what?
protons + electrons= atomic mass NUMBER, not the atomic mass.
What atomic mass is equal to the atom on the periodic table?
number of protons = atomic mass
What do atomic number and atomic mass mean?
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.
Is it true that The atomic mass is equal to the atomic number?
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.
What best describes the number of neutrons in an atom?
It is equal to the difference between atomic number and Atomic Mass number. A+
What is equal to the total number of protons and neutrons?
If you add the number of protons to the number of neutrons in an atom, you have calculated that atom's atomic mass.
What number is the atomic mass equal to?
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.
Is the mass number of an atom equal to the atomic number?
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.
What is the atomic mass of a 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 atomic mass of an atom is equal to?
the total mass of its protons, neutrons, and electrons.
What is the unified atomic mass unit equal to?
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.
