A proton has slightly less mass than a neutron.
electron is least, followed by proton and then neutron. Nucleus will have the highest mass as nucleus contains both protons and neutrons.
The nucleus of an atom always contains at least 1 proton. It almost always contains at least 1 neutron as well.
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 mass of an electron is the least among the options given here.
A neutron has no electrical charge and is found in the nucleus of an atom.Alternate wording to an inexact question:If you are referring to the nucleus of an atom, there must always be at least one proton. So there has to always be a positive charge. The other component, the neutron, has no charge. The electrons orbiting the nucleus have the negative charge. So if no electrical charge is found in the nucleus, it is not an atom and therefore not a nucleus.
An atom is made up of three parts. The protons, neutrons, and electrons. The protons and neutrons are located in the center of the atom called the nucleus. The electrons float around the atom in what is called orbitals.
It is very simple. The hydrogen atom is composed of a nucleus with only one proton and an electron around the nucleus.
No, it cannot exist because without any neutrons, the protons will repel each other since the nucleus would have multiple positive charges.
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.
In the case of a normal hydrogen atom the nucleus is only one proton, there are no neutrons. However, every other atom and molecule (apart from H2) has at least one neutron in the nucleus.
atom can not exists without protons. At least one proton is necessary to form an atom. For example hydrogen atom. It does not contain neutron. All other atoms has got neutrons also in the nucleus.
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)
