There exists no mass less atoms. Every atom has a mass.
1.6749x10-24
atomic mass is the number of protons in the nucleus of an atom.It can also be equal to the number of electrons in a neutral atom
A neutral atom that is not an isotope with an atomic mass of 32 is sulfur. Sulfur belongs to group XVI.
Neutron. It is electrically neutral, and coincidentally about as massive as a proton plus an electron.
Neutron
A neutral atom with an atomic mass of 36 amu will have 36 electrons. This is because the atomic mass of an atom is determined by the sum of its protons and neutrons, and in a neutral atom, the number of electrons is equal to the number of protons.
Mass number increases as neutron is added
Atomic number = number of protons or electrons (in a neutral atom) Mass number: sum of protons and neutrons The mass number is bigger.
well i asked you.
For an atom... ( proton mass * number of protons + neutron mass * number of neutrons + electron mass * number of electrons ) - mass of atom in neutral state = mass deficit
An atom that has a neutral charge is one with which the quantity of electrons is equal to the atomic number.
The mass number is the number of protons and neutrons added together. Electrons are not counted as part of the mass because while protons and neutrons weigh the same, Electrons weigh virtually nothing compared to them. As far as I can tell, there is no stable atom with a mass of 8.
