Protons are part of the nucleus, so they have less mass than the nucleus (except in the specific case of hydrogen, where the nucleus is a single proton so they have the same mass).
Electrons are much less massive than protons. It would take 1836 electrons to equal the mass of one proton.
Neutrons are very slightly more massive than protons, by just about the mass of an electron. They're close enough that they're generally treated as having essentially the same mass.

Have about 1800 times less mass than protons and neutrons?
Electrons have ~1800 times less mass than protons and neutrons
What is the mass of an atom that has 92 protons and 108 neutrons?
If you have 92 protons and 108 neutrons you will get 200 electrons
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.
What are properties of Mercury?
A mercury has an atomic mass of 200.59 and it has 80 protons and electrons
Does the volume of matter come from protons or electrons?
The number of electron orbitals is where the volume of matter comes from. The more electrons and orbitals, the more volume. The mass comes from the protons and neutrons.
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
Protons and electrons have this?
Protons have a positive electric charge while electrons have a negative charge.
What is the mass of an atom mainly determined by?
The mass of an atom is mainly determined by the combined mass of its protons, neutrons, and electrons. Protons and neutrons contribute most of the mass, while electrons have a much smaller mass.
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.
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.
What has the smaller mass protons electrons or nutrons?
Electrons have the smallest mass compared to protons and neutrons. The mass of a proton is approximately 1836 times greater than the mass of an electron, and the mass of a neutron is slightly greater than that of a proton.
What determines the mas of an atom?
The mass of an atom is determined by the combined mass of its protons, neutrons, and electrons. Protons and neutrons are the primary contributors to the mass, while electrons have a negligible mass in comparison.
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
What particles make up the mass of an atom?
The number of protons
