Well, that's kinda a trick question because an electron is pure energy. An electron particle is also the smallest of the 4, so its the electron (eventhough an electron is a weichtless particle such as a graviton or magneton!
Hope I helped!!
The smallest and least energetic path of an electron around a nucleus is the ground state, or lowest energy level. In this state, the electron occupies its lowest energy orbital closest to the nucleus.
Adding an electron to an orbital does not necessarily mean adding a neutron. Neutrons are not directly related to the number of electrons in an atom. Neutrons are added to the nucleus of an atom independently of the electrons in the electron cloud.
The space surrounding the nucleus.
The electrons with the least amount of energy in a calcium atom in the ground state are located in the innermost electron shell, closest to the nucleus. These electrons have lower energy levels as they are shielded by the outer electron shells.
Electrons are attracted to the positive charge on the nucleus. The further an electron is found from the nucleus of an atom, the lower the force of attraction between it and the nucleus. Therefore an electron far away from the nucleus (like a valence electron) will have less of an attraction to the nucleus than one close to it. A lower attraction to the nucleus translates into the fact that less energy would then be required to remove the electron from the vicinity of that nucleus.
An electron.
electron is least, followed by proton and then neutron. Nucleus will have the highest mass as nucleus contains both protons and neutrons.
The mass of an electron is the least among the options given here.
LEAST mass? That would be photos or neutrinos, which have no mass at all. Where Least is greater than zero? Electrons, probably; an electron is 1/1836th of a proton, I seem to recall. Neutrinos actually have a small nonzero mass, so small it has yet to be determined. No neutrino has a mass of more than a few eV, the electron has a mass of about 0.5MeV.
the particles that make up an atom are; a proton/protons a neutron/neutrons an electron/electrons these are also made up of other particles but to go any further into this subject would require that you have at least a basic understanding of quantum mechanics and these particles are not important at any educational level below degree level (generaly speaking)
A proton has slightly less mass than a neutron.
An atom consists of three basic components: electrons, protons and neutrons. The three particles are listed in order of least massive to most massive. A neutron is slightly more massive than a proton, and these two particles make up the nucleus of an atom. Electrons are the smallest particles found in an atom, and an electron is less than 1/1800th the mass of a proton. They are so small that their mass is not even taken into consideration when calculating the mass number (protons plus neutrons) of an atom, even in larger atoms with large numbers of electrons.
No! The nucleus of an atom consists of at least one proton and, in all but one instance, at least one neutron. An atomic nucleus does not include electrons.
The smallest and least energetic path of an electron around a nucleus is the ground state, or lowest energy level. In this state, the electron occupies its lowest energy orbital closest to the nucleus.
among these Electron has the least mass....
The nucleus of an atom always contains at least 1 proton. It almost always contains at least 1 neutron as well.
Adding an electron to an orbital does not necessarily mean adding a neutron. Neutrons are not directly related to the number of electrons in an atom. Neutrons are added to the nucleus of an atom independently of the electrons in the electron cloud.
