How many subatomic particles are in an atom? The amount of which subatomic particle is different between an atom and its ion? Which two particles in an atom are equal in number? What is the mass number of an atom? What is the average mass of a single silicon atom ...
The mass number of an atom is the total number of protons and neutrons contained within the nucleus of the atom. The number of protons determines the element and will always equal the atomic number of that element. The number of neutrons can change and will determine which isotope of that...
Mass Number It is the sum of neutrons and protons of an atom present in nucleus. Mass Number for two different atoms can be same. The Atomic Mass of an atom is approximately equal to its Mass Number as mass of a neutron as well of a proton is one unit on atomic mass scale.Email...

The atomic mass is the mass of an atom. Although the SI unit of mass is the kilogram, the atomic mass is often expressed in the non SI-unit dalton, where one dalton is defined 1/12 of the mass of a single carbon-12 atom, at rest. The protons an...
What is the center of an atom called?Atoms:Atoms are the smallest indivisible working unit of matter. It is composed of three subatomic particles: neutrons, electrons, and protons. Neutrons are neutrally charged whereas electrons are negatively charged. Protons are the subatomic particles of an ...
