Neutron has the highest mass in this group. Proton mass is just less than that of neutron. Electron and positron are anti particles to each other. They have opposite quality only due to charge polarity. Both have same mass. Mass of electron is some 1836 times less than that of proton. Please note down the different quantities.
Proton, photon and positron.

∙ 13y agoA molecule can have the greatest mass; but the mass of a molecule depends on the chemical composition; consequently it is very common for a specific molecule to have a mass lower that the mass of an atom.

Protons and electrons have this?
Protons and electrons have mass and charge.
Why mass of electrons is excluded from atomic mass?
The mass of electrons is not excluded from atomic mass. The mass number of an isotope of an element excludes electrons because it is the sum of protons and neutrons.From Wikipedia, "The atomic mass (ma) is the mass of a specific isotope, most often expressed in unified atomic mass units. The atomic mass is the total mass of protons, neutrons and electrons in a single atom."
Do electrons make up most of an atom?
Protons and neutrons form the most of the atomic mass.
What is The atomic mass of an element is equal to?
The number of protons, electrons, and neutrons:P
Which term describes the sum of the number of protons and neutrons in an atom?
when you could check in most of atoms that we have you will see that the sum of protons and electrons equals to or is called the atomic weight or atomic mass...that is if you add protons to electrons you have your atomic mass.
Protons and electrons have this?
Protons and electrons have mass and charge.
What is the number of protons in the necleus?
# of protons = # of electrons # of protons/ electrons + # of neutrons = atomic mass
How are electrons and protons related?
For a stable atom, no. of protons= no. of electrons no of neutrons= Atomic Mass- no. of protons
How many protons neutrons and electrons does Ca have?
Electrons have no relevant mass, and protons and neutrons both have the mass of 1u. If Calcium has the number 20, it has 20 protons (and electrons). It's mass is about 40u. Core Mass - Protons = Neutrons 40u - 20u = 20u, this means Calcium has 20 electrons, 20 protons and 20 neutrons.
What has the smaller mass protons electrons or nutrons?
Electrons have a smaller mass than both protons and neutrons. Both protons and neutrons are over 1800 times as massive as electrons.
Why mass of electrons is excluded from atomic mass?
The mass of electrons is not excluded from atomic mass. The mass number of an isotope of an element excludes electrons because it is the sum of protons and neutrons.From Wikipedia, "The atomic mass (ma) is the mass of a specific isotope, most often expressed in unified atomic mass units. The atomic mass is the total mass of protons, neutrons and electrons in a single atom."
Which subatomic particles makes up most of the mass off the atom?
The major contribution to the mass of an atom is from protons and neutrons; electrons have a known but negligible mass.
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.
Why do protons and electrons aproximately equal a atomic mass?
Protons are much heavier (1800 X approx) than electrons! Atomic mass is due to the mass of the protons and neutrons only a very small % of atomic mass is due to electrons.
Do electrons make up most of an atom?
Protons and neutrons form the most of the atomic mass.
What is the atomic mass the same as?
The Atomic Mass is equal to the number of protons and electrons that an element has.
What is The atomic mass of an element is equal to?
The number of protons, electrons, and neutrons:P
