The mass number of an atom is equal to what?
proton
What is the mass number of atom equal to?
proton
What is a direct consequence of the number of protons and neutrons in an atom's nuceuls?
Number of proton = atom numberfor example:Hydrogen has 1 proton and its atom number is also 1Number of neutrons + number of protons = mass numberfor example:Hydrogen have 1 proton and and NO neutrons, so the mass number is 1Helium has 2 protons and and 2 neutrons, so the mass number is 4
What represents the sum of proton in the nucleus of an atom?
mass number
What type of particle has an atomic number of 1 and a mass number of 1?
Of the common sub-atomic particles, both the proton and the neutron have mass numbers of 1.

What is the mass of an atom found by?
Mass of an atom = Mass of proton + Mass of neutron
A postively charged particle in an atom?
The positively charged particle in an atom is the proton. The negatively charged particle is the electron. The electrically neutral particle is the neutron.
What are the units for mass defect?
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
What important number in an atom distinguishes that atom from every other type of atom?
I believe the Proton Number (being the number of protons in the centre/nucleus of the atom) is the most important number in an atom. Oxygen for example has 8 protons and 8 neutrons. if it had more/less neutrons it would still be oxygen (it would be an ISOTOPE of oxygen) but if it had more/less protons, it would be a differnet element entirely. Ordinarily, the number of protons in an atom matches the number of electrons spinning around the outside so as to keep it neutral. (a proton has a positive charge and a neutron has a negative charge) the relative atomic mass of an element is the proton number + the neutron number as electrons weigh so little their mass is not worth taking into account.
Why isnt the mass of the electron included in the mass of an atom on the periodic table?
the mass of electron is very less compared to that of a proton or a neutron it is 1/1800 the mass of 1 proton and therefore it is negligible and not included.
What is the formula for atomic number?
atomic number = number of proton in an element number of proton = number of electron mass number = number of proton + number of neutron therefore... atomic number = mass number - number of neutrons
How do you determine the atom the atomic mass of an atom?
Proton + Nuetron = Atomic Mass
