Protons and neutrons have a mass of approximately 1 amu (atomic mass unit). The electrons way so little that we usually do not count their mass. To find the atomic mass, you need to add the number of protons to the number of neutrons in an atom.

Where is the mass found in an atom found?

Most of the mass of an atom is found in the nucleus which contains the protons and neutrons.


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 the mass in atom?

Most of the mass in an atom is found in the nucleus, which contains the protons and neutrons.


Where are protons found in the nucleus of an atom?

Protons, and neutrons make up the nucleus of an atom. The nucleus is the centre of an atom where most of the mass is found. Protons are positively charged, neutrons have no charge.


Where is most of the atoms mass found?

An atom's mass is concentrated in its nucleus, which is located in the center of the atom. Protons and neutrons within the nucleus are responsible for its mass; the electrons, which are located outside of the nucleus, don't contribute to the mass of the atom.


In atoms protons and neutrons are found where?

Protons and neutrons are found in the nucleus of an atom. Protons have a positive charge, while neutrons have no charge. Together, they make up the majority of an atom's mass.


What information does the atomic mass of an elemt provide?

the number of protons and neutrons in an atom. Atomic mass is found by adding together the individual masses of the numbers of protons, neutrons, and electrons in the atom. --> Atomic Mass = protons + neutrons


The mass number of an atom is found by adding the?

The mass number of an atom is found by adding the number of protons and neutrons in its nucleus. It is an integer value that represents the total number of nucleons in the atom.


Subatomic particles responsible for most of an atom's mass?

Protons and neutrons are subatomic particles that are responsible for most of an atom's mass. Protons have a positive charge, neutrons are neutral, and both are found in the nucleus of an atom. Electrons, which have a much smaller mass, orbit around the nucleus.


What particles are used to determined the mass of an atom?

Mass of an atom = mass of protons + mass of neutrons


What is the sum of protons and neutrons in an atom?
