Do protons nuetrons and electrons all have about the same mass?
Protons and neutrons have about the same mass, but electrons are much, much lighter.
What two particles make up the atomic mass?
The atomic mass is made up of protons and neutrons in the nucleus of an atom. Protons have a positive charge, while neutrons have no charge. Electrons, which have a negative charge, are not included in the atomic mass as they are much lighter than protons and neutrons.
Why are only protons and neutrons used to calculate atomic mass?
Protons and neutrons are used to calculate atomic mass because they are the fundamental components located in the nucleus of an atom. Electrons are much lighter and are not included in the atomic mass calculation because their mass is negligible compared to protons and neutrons.
Are neutrons the lightest subatomic particles?
Neutrons are not the lightest subatomic particles. Electrons are the lightest subatomic particles, with a much smaller mass than neutrons. The mass of a neutron is approximately 1839 times that of an electron.
How much neutrons does molybdenum have?
Most molybdenum atoms have 54 neutrons. The atomic number (number of protons) of molybdenum is 42, and its weight (number of protons and neutrons) is around 96. 96 - 42 = 54.
What is counted in an atom to determine mass number?
The mass number of an atom is determined by counting the total number of protons and neutrons in its nucleus. Electrons, which are much lighter than protons and neutrons, are not included in the mass number calculation.
The atomic mass of an element is determined by its total number of?
protons and neutrons in the nucleus. It is calculated by adding the number of protons and neutrons in an atom. Electrons do not significantly contribute to the atomic mass due to their much smaller mass compared to protons and neutrons.
Are electrons larger than neutrons and protons?
no. protons and neutrons are MUCH larger than electrons.
Why is the atomic mass the same as the total number of protons and neutrons in the nucleus?
The atomic mass is the sum of the number of protons and neutrons in the nucleus because protons and neutrons have a mass of approximately 1 atomic mass unit each. Electrons are much lighter and do not significantly contribute to the overall mass of the atom.
How do the different subatomic particles differ?
Protons have a positive charge, neutrons have no charge, and electrons have a negative charge. Protons and neutrons are found in the nucleus of an atom, while electrons orbit around the nucleus. Protons and neutrons have approximately the same mass, while electrons are much lighter.
What are the relative atomic mass of subatomic particles in atom?
The relative atomic mass of electrons is considered negligible, as they are much lighter than protons and neutrons. Protons and neutrons each have a relative atomic mass of approximately 1, as they are found in the nucleus of an atom and contribute to its overall mass.
Do neutrons weigh as much as protons?
Yes.
