What are the particles in the atom that account for most of the mass of the atom are protons and electrons?
The particles in an atom that account for most of its mass are protons and neutrons, not electrons. Protons, which are positively charged, and neutrons, which have no charge, reside in the nucleus and contribute significantly to the atomic mass. Electrons are much lighter and orbit the nucleus, but their mass is negligible compared to that of protons and neutrons. Thus, the majority of an atom's mass comes from the nucleus.
What is determined the mass of an atom?
The mass of an atom is determined by the sum of the masses of its protons, neutrons, and electrons. The protons and neutrons are located in the nucleus and contribute most of the mass, while the electrons, which have much less mass, orbit the nucleus. The mass of an atom is typically measured in atomic mass units (amu).
What atomic particles carry mass?
Protons, neutrons, and electrons are atomic particles that carry mass. Protons and neutrons contribute most of the mass to an atom's nucleus, while electrons have a much smaller mass compared to protons and neutrons.
Which particles account for most of an atoms mass?
Almost all of the mass in an atom is made up from the protons and neutrons in the nucleus, with a very small contribution from the orbiting electrons
Why do you only include the mass of the protons and neutrons in the nucleus?
The mass of protons and neutrons contributes almost all of the mass of an atom, while the mass of electrons is much smaller and negligible in comparison. Electrons are much lighter compared to protons and neutrons, so their contribution to the total mass of an atom is often ignored in most calculations.
What is the mass of an atom mainly determined by?
The sum of masses of protons, neutrons and electrons.

What is the mass of an atom found by?
The mass of an atom is primarily determined by the combined masses of its protons, neutrons, and electrons. Protons and neutrons contribute most of the mass since electrons have negligible mass. The exact mass of an atom can be found by adding up the masses of its protons, neutrons, and electrons.

Where is most of the mass of an atom contained?
When calculating the mass of an atom, you add the mass of the protons and the neutrons. This is the nucleus of the atom. The electrons are small enough to be ignored except in the most delicate calculations.
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
Which particles account for most of an atoms mass?
Almost all of the mass in an atom is made up from the protons and neutrons in the nucleus, with a very small contribution from the orbiting 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.
Why do you only include the mass of the protons and neutrons in the nucleus?
The mass of protons and neutrons contributes almost all of the mass of an atom, while the mass of electrons is much smaller and negligible in comparison. Electrons are much lighter compared to protons and neutrons, so their contribution to the total mass of an atom is often ignored in most calculations.
Protons and electrons have this?
Protons and electrons have mass and charge.
