Do protons neutrons and electrons affect the mass and charge of an atom?

Answer 1

Mass is a measurement of the amount of matter in an object. An atom has mass. The Atomic Mass is made up of protons and neutrons because both of these particles make up the atom's nucleus and have mass. Electrons also make up an atom, but their masses are so small that they are not usually calculated in with the atomic mass.

Answer 2

Yes, protons and neutrons contribute to the mass of an atom, with protons having a positive charge and neutrons being neutral. Electrons have a negligible mass but contribute to the overall charge of an atom by balancing the positive charge of the protons.

Answer 3

Protons and neutrons influence an atom's mass because an atom is made up of protons and neutrons. The number of protons and neutrons determine the atomic mass (which is the #of protons + neutrons).

Answer 4

The atomic number is an indicator of how many protons are in an atom. Thus the larger the atomic number, the more protons, and the higher the subsequent atomic mass due to the additional number of protons.

Answer 5

Each neutron contributes one atomic mass unit to the mass number, which is a characteristic of a particular isotope of an element rather than of the element itself. The weighted average of the mass numbers of the constituent isotopes is the atomic mass of the element, which is usually not an integer.

Answer 6

Yes, if you add the number of protons and neutrons you will get the atomic mass. Same way if you look at the Periodic Table and if you subtract the number of protons being the atomic number from the atomic mass you will have the number of neutrons.

Answer 7

Because electrons are about 1/2000 times the mass of a neutron, even though they have the opposite charge to a proton. A proton has a very slightly lower mass than the neutron, but it's still about 2000 times that of an electron.

The charge of an atom, on its own, is neutral, so there are as many protons as electrons, and usually a few neutrons kicking about, making it impossible for the majority of the mass to come from the electrons.

Answer 8

No, a proton has a mass of about 1.007 atomic mass units, whereas an electron has a mas of about .000549 atomic mass units. Protons are about 1836 times more massive than electrons. Neutrons have a mass of 1.008 amu

Answer 9

The sum of an atom's neutrons and protons determine the mass of an atom.

Answer 10

protons and neutrons affect the mass electrons and protons affect the charge
