What is a particle that revolves around the nucleus of an atom?
a particle that revolves around the nucleus of an atom is an electron Electrons
In an atom the particles with a negative charge are called what?
a particle with a negative charge in an atom is an electron
Neutral particle of an atom found in the nucleus?
neutrons
Positively charged particle consisting of 2 protons and 2 neutrons which is given off by a radioactive substance is called what?
A radiation particle consisting of two protons and two neutrons is called an Alpha Particle. Alpha Particles have the same structure as a Helium nucleus. There are three forms of radiation, Alpha (Helium nucleus), Beta (a lone electron) and Gamma (an Electromagnetic wave).
The particle in the nucleus of an atom with no charge?
It is called the nucleus and has a mass unit number of one.
What particle in the atom is the least massive?
least - electron most - the top quark
Which in an atom has the least mass in an atom?
Which particle? The electron.
What subatomic particle is the least and most massive and which subatomic particle is respectively?
least - electron most - the top quark
What particle is least massive?
The least massive principle atomic particle is the electron. Neutrons and protons are much more massive and are about equal in mass. Of course, there are even smaller particles such as quarks which are less massive than even electrons.
What particle found in an atom has the least mass?
the electron
How massive is a alpha particle?
an alpha particle is made of two protons and 2 neutrons. its basically the same as the nucleus of a helium atom
Subatomic particle that has the least mass?
In the atom this particle is the electron. Generally in the particle physics: photons, gluons, neutrinos.
Why do alpha particle have higher ionizaion energy than beta particle?
Alpha particles are far more massive. Alpha particle is an (ionized) helium atom, a beta particle is just an electron.
What stable particle found in an atom has the least mass?
the electron
What is heaviest particle found in the nucleus of an atom?
Neutrons are... very slightly... more massive than protons.
Where in the periodic table would have the least massive atom?
The element hydrogen is least massive as it has only one proton, one electron.
Which subatomic particle is least massive?
The three main subatomic particles are the proton, neutron, and electron. Of these three, the electron has the least amount of mass at about 0.0005 amu or atomic mass units.
