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.
What else can I help you with?
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.
Protons and electrons have this?
Protons and electrons have mass and charge.
Which particles account for most of an atoms mass?
Protons and neutrons are the particles that account for most of an atom's mass. Electrons, which have much less mass, play a negligible role in the overall mass of an atom.
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."
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.
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 is the number of protons in the necleus?
# of protons = # of electrons # of protons/ electrons + # of neutrons = atomic mass
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.
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.
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 and electrons have mass and charge.
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.
Which particles account for most of an atoms mass?
Protons and neutrons are the particles that account for most of an atom's mass. Electrons, which have much less mass, play a negligible role in the overall mass of an atom.
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."
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.
