What does the mass of an atom consist of?

Answer 1

the mass of an atom is concentrated in a very small central portion of the atom which is called the atomic nucleus. The atomic nucleus is made up of nucleons, of which there are two important fundamental types: electrically positive protons and electrically neutral neutrons. So the Answer for the question is: Neutrons and Protons.

Answer 2

The mass of an atom consists of protons, neutrons, and electrons. Protons and neutrons are located in the nucleus and contribute most of the atom's mass, while electrons, which have a much smaller mass, orbit around the nucleus.

Answer 3

What the atomic mass of an atom consists of?ding a ling.

Answer 4

The Atomic Mass is the weight of both the protons and the neutrons.

e.g oxygen has and atomic mass of 16 and a atomic number of 8

16-8(protons)= 8 neutrons

Answer 5

All particles of an atom have some mass. However, the vast majority of the mass is believed to be the protons and neutrons.

Answer 6

The major portion of an atom's mass is made up of protons and neutrons.

Answer 7

protons, electrons and neutrons

Answer 8

Neutrons and protons.

Answer 9

The nucleus contains the mass.
