answ2. Protons and neutrons are all.
These may be divided into further parts, but that is beyond the question.
Valence electrons are located farthest from the nucleus of the atom.
The centre of an atom is called the nucleus. The nucleus contains protons, which have a positive charge and neutrons which have no charge. Electrons are also subatomic particles but they go around the nucleus so they are not in the centre.
All elements have three subatomic particles: Protons: positive forces, centered in the nucleus of the atom with neutrons Neutrons: neutral forces, centered in the nucleus of the atom with protons Electrons: negative forces, centered in different energy levels outside the nucleus of the atom Between all these particles, there is only empty space; nothing.
The only non-radioactive isotope with the specified properties is silicon-28, which constitutes more than 90 % of naturally occuring silicon.
A neutral nitrogen atom has 7 protons and 7 neutrons in its nucleus and 7 electrons in orbitals around the nucleus.
because they are contained inside the subsection of the atom (nucleus.)
Nucleons, comprising protons and neutrons, are the generic name for the subatomic particles found in the nucleus of an atom.
Protons
Protons and neutrons are the subatomic particles found within the nucleus of an atom. Electrons are found outside the nucleus in electron clouds.
the subatomic particles, protons and neutrons, form the nucleus.
The three subatomic particles are the proton, the neutron, and the electron. Protons and neutrons are located inside the nucleus. Electrons are located outside of the nucleus in the electron cloud.
It is the neutron and proton that make up the nucleus of an atom. The only exception is Hydrogen (isotope mass number 1), having only one (single) proton in its nucleus and no neutrons. All other atoms have a nucleus that is made up of combinations of these two subatomic particles.
Electrons are the subatomic particles ouside the nucleus of the atom.
protons and neutrons
Proton and neutron.
Protons and neutrons are the two subatomic particles that make up the nucleus of an atom.
Protons and neutrons are found inside the nucleus of an atom. Electrons orbit around the nucleus in energy levels.
