What electrons are the reactive particles of the atoms?
The Outermost Electrons are the reactive particles of the atoms.
What is true of an atoms's nucleus?
negatively charged and takes up most of the atoms space Takes up most of the atoms mass and is negatively charged
Where is most of potassium atoms mass located?
The nucleus - protons and neutrons. This applies to all atoms.
Why do atoms have no electric charge even though most Of their particle have charges?
The negative particles (electrons) are balanced by the positive particles (protons).
What particles make up most of the mass atom?
air,mater
What subatomic particles responsible for most of an atoms mass?
These particles are the protons and neutrons.
Which particles account for most of the atoms mass?
Physics has not managed to discover a particle that accounts for mass
Which subatomic particles account for most of an atoms mass?
The up and down quark accounts for most of an atoms mass. Two up quarks and one down quark forms a proton, and one up quark and two down quarks forms a neutron. Protons and neutrons form the nuclei of atoms, and comprise most of their mass, along with the binding energy holding them all together.
Which two particles make up most of the mass of a hydrogen-2 atom?
The proton and the neutron make up most of the mass of a hydrogen-2 atom.
What 2 particles have similar masses?
Protons and neutrons have near identical mass. One will not have to account for the difference in mass in most calculations.
Which two subatomic particles make up most of the atoms mass Where are they located?
These particle are neutrons and protons; they are located in the atomic nucleus.
What are the particles in the atom that account for most of the mass of the atoms are protons are?
Neutrons is the answer. Both protons and neutrons have almost equal mass and concentrated in nucleus. Electrons have negligible mass as compared to mass of protons and neutrons and such minor figures are discarded in physics as much as mass isconcerned. Mass of electron is 1/1836 as compared to proton. But electric charge wise 'both' are equal and apposite.
Who said most of an atoms mass is in the nucleus in an atom?
Ernest Futher Ford
What is pair of particles with nearly the same mass?
Protons and neutrons have near identical mass. One will not have to account for the difference in mass in most calculations.
What electrons are the reactive particles of the atoms?
The Outermost Electrons are the reactive particles of the atoms.
Which particles contribute to most of the atoms volume and size?
These particles are protons and neutrons.
What is the most of the mass of an atoms?
The nucleus.
