What else can I help you with?
How many subatomic particle would be present in an atom of helium with a mass of 4 amu?
6 subatomic particles. 2 protons and 2 neutrons (that accounts for the mass of 4 amu) as well as 2 electrons.
What subatomic particles are closest in mass proton and neutron neutron and electron proton and electron electron and ion?
Mg+2 and Br-1
What are the electrical charges of the three subatomic particles?
Three Subatomic Particles: 1) Neutrons- neutral (no) charge. 2) Protons- positive charge (+) . 3) Electrons- negative charge (-) .
Are subatomic particles partial particles?
no, a molecule is composed of 2 or more atoms.
Which of these subatomic particles contain the heaviest particles?
Hey, it's Song_Writer_Girl13 here! Protons have a +1 (postive) charge and a mass of 1 Neutrons have no electric charge and have a mass of 1 Electrions have a -1 (negative) charge and have a mass of about 0 (there actual mass is so small we just say it's about 0) Therefore, electrons have the greatest mass of the three subatomic particles. Hope I helped!
Which 2 subatomic particles are found in the nucleus?
The two subatomic particles found in the nucleus are protons and neutrons. Protons have a positive charge, while neutrons have no charge.
What subatomic particles are presant in an alpha particale?
2 protons, 2 neutrons
Where are the subatomic particles in protons?
A proton contain 2 up quarks and 1 down quark; quarks are bonded by gluons.
What are the two parts of a subatomic particle?
Subatomic particles are made up of 2 parts; composite particles and elementary particles. The composite particles consist of the protons and neutrons comprised in an atom. The elementary particles have no substructure and are not made up of any other particles.
What subatomic particles compose the mass of an atom?
All subatomic particles have mass, bar the photon and the gluon. The masses of some of the most well-known are as follows: Electron: 0.511 MeV/c^2 Proton: 938.272 MeV/c^2 Neutron: 939.565 MeV/c^2 Electron Neutrino: ~2.2 MeV/c^2 N.B: All masses have been expressed using Einstein's mass-energy equivalence (E=m.c^2); the mass is thus expressed in terms of energy/c^2 as the masses (in kg) would be extremely small.
What 2 subatomic particles are stationary?
You think probable to protons and neutrons.
2 subatomic particles have the same charge?
Protons have positively charged particles, Electrons have negatively charged particles, and Neutrons don't have and charged particles
