This is Carbon-12 (12C) it has a mass of exactly 12 universal Atomic Mass units. It serves as the standard for the universal atomic mass scale.
If you look up carbon on the Periodic Table, you will find that it says 12.011. This difference is because a small amount of carbon has a seventh neutron, which is averaged into the atomic weight given on a periodic table.
For a stable atom, no. of protons= no. of electrons no of neutrons= atomic mass- no. of protons
Electrons, protons, and neutrons are all located in an atom. Protons and neutrons are placed in the atomic nucleus.
For a stable atom, no. of protons= no. of electrons no of neutrons= Atomic Mass- no. of protons
Atomic mass is the total mass of protons, neutrons and electrons in a single atom.
The atomic nucleus has protons and electrons.
neutrons, protons and electrons can be located in a atom The protons and neutrons are located in the atomic nucleus; the electrons are around the nucleus, arranged in shells.
Protons, neutrons and electrons are located in the atom. The protons and neutrons are located in the atomic nucleus; the electrons are around the nucleus, arranged in shells.
Atomic number is the number of protons in an atom. In a neutral atom the numbers of protons and electrons are equal. So if you know the atomic number of a neutral atom, you will also know the numbers of protons and electrons. Mass number is the sum of protons and neutrons in a particular isotope of an atom. Since atomic number is the number of protons in an atom, subtract the atomic number (or number of protons) from the mass number to get the number of neutrons. Mass no. - atomic no. = no. of neutrons or mass no. - no. of protons = no. of neutrons.
IF you know the atomic mass and the atomic number the atomic no. is the number protons and electrons(number of protons is the same as the number of electrons) and whatever the atomic mass - protons and you will get the number of neutrons
What is the atomic mass of atom with 23 protons 24 neutrons and 25 electrons? is it 72 actually its protons + neutrons = atomic mass, therefore it is 23+24= 47.
protons 26 electrons 26 neutrons Iron will have 26 electrons 26 protons (they are = because the atom is neutral) and it will have 30 neutrons (because protons + neutrons= your atomic weight) electrons have virtually no mass If the iron atom had a +2 charge there would be two less electrons than protons. 26 protons 24 electrons 30 neutrons.
atomic number = number of protons = 6
electrons= 17, protons =17, neutrons=20 atomic no.=no of protons=17 atomic mass=no. of protons+ no. of neutrons=17+20=37
these are electrons, protons and neutrons.
They are neutrons, protons, and electrons.

Protons, neutrons and electrons
6 protons, 6 electrons and 8 neutrons
In the neutral atom the number of electrons and protons is equal to the atomic number.The number of neutrons is mass number-number of protons.
the number of protons and neutrons in an atom. Atomic mass is found by adding together the individual masses of the numbers of protons, neutrons, and electrons in the atom. --> Atomic Mass = protons + neutrons
Atomic number is the number of protons and electrons in a neutral atom. Atomic mass minus atomic number is the number of neutrons in the atom. Neutrons and protons have relatively equal masses and electrons are comparatively "weightless" therefore, the sum of the masses of protons and neutrons equals the atomic mass.
Americium has 95 protons and electrons. Number of neutrons: atomic mass of an isotope - number of protons
The atomic number = number of protons. The Atomic mass = Protons + Neutrons.
The atomic mass NUMBER of an atom is equal to the sum of the protons and neutrons of the atom. The atomic mass of an atom is the total mass of the electrons, protons, and neutrons in a motionless atom.
Neutrons and protons are components of the atomic nucleus. The electrons orbit these in imaginary shells.
