# Where is most of the mass of the atom found?

## Where is most of the mass of the atom found?

nucleus
The nucleus contains the majority of an atom’s mass because protons and neutrons are much heavier than electrons, whereas electrons occupy almost all of an atom’s volume. The diameter of an atom is on the order of 10−10 m, whereas the diameter of the nucleus is roughly 10−15 m—about 100,000 times smaller.

Where is most of the mass in an atom located is this the largest part of the atom?

Protons and neutrons are found inside the nucleus. Most of the mass is concentrated in the nucleus.

### Which atom has the most mass?

Oganesson
Oganesson has the highest atomic number and highest atomic mass of all known elements.

What has the largest mass in an atom?

Atoms have most of their mass in the nucleus not only because protons and neutrons are heavier than electrons, but also because together, protons and neutrons outnumber electrons by roughly 2:1.

Which subatomic particles make up most of the mass of an atom?

Most of the mass of an atom is situated within the nucleus, which is the central part of the atom. It is made up of protons and neutrons, which are the heaviest subatomic particles.

### What part of an atom has the smallest mass?

Electrons are the least massive of an atom’s constituent particles, with a mass of 9.11 x 10 -31 kg and a size too small to be measured by current techniques.

What does the atomic mass tell you about an atom?

Atomic mass of an element tells us the number of times an atom of the element is heavier than of the mass of an atom of carbon-12. A unit suitable for the mass of atoms and the mass of subatomic particles is the atomic mass unit (u).
