What does the neucleus contain?
It contains most of the atom's mass.
Made up of the protons and neutrons this part of the atom contains nearly all the mass of the atom?
The nucleus is the part of the atom made up of protons and neutrons, and it contains nearly all of the atom's mass. Electrons, which have much lesser mass, orbit around the nucleus.
What is the sum of protons and neutrons in the neucleus of an atom?
Its mass number (largest number written near an element in the periodic table)
Where is he mass of an atom concentrated?
99.9% of the mass of an atom is located in the nucleus
What is the meaning of the word neucleus?
If you mean 'nucleus' it is the central part around which other parts are grouped. In physics, it is the positively chargesd mass within an atom
What does the atomic mass of an element equal to?
no. of protons in its neucleus
Rutherford said that almost all the mass of an atom is located in its what?
Rutherford discovered in the early 1900s that most of an atom's mass is located in its nucleus.
Where is the protons located on an atom?
The proton is located in the atom's nucleus, with the neutrons (if there are any).
Where is most of the mass located in am atom?
nucleus
What is the heaviest part in a atom?
The most mass of a atom is located in the nucleus, where the protons and the neutrons are located.
Where is almost all of the mass in an atom is located?
Approximately all of the atom's mass is in the nucleus. The electrons contribute almost zero.No atom has more than 100 electrons, but eachproton or neutron in the nucleushas the mass of more than 1,800 electrons.
What is the Mass of an atom is located in what structure of the atom?
In the nucleus of the atom, protons and neutrons therein each add 1 atomic mass unit.
