D.) Electrons exist in energy levels
Electrons, small negatively charged particles with very little mass compared to that of the nucleus.
Electrons are extremely small compared to neutrons. Electrons have a negative charge and surround the nucleus in a kind of 'cloud'. Neutrons have no charge and are located in the nucleus of an atom.
Electrons are the negatively charged particles that orbit the nucleus of an atom. They have a much smaller mass compared to protons and neutrons, and their movement creates the electron cloud that surrounds the nucleus.
Electrons are negatively charged particles that orbit the nucleus of an atom, while protons are positively charged particles found in the nucleus, and neutrons are neutral particles also found in the nucleus. Electrons are much smaller in mass compared to protons and neutrons.
The nucleus contains protons and neutrons and is orbited by electrons. ( Apex 2021)
Valance electrons are not located near the nucleus. These electrons are in fact located the furthest away from the nucleus compared to other electrons.

Yes, electrons in higher energy levels are farther from the nucleus compared to electrons in lower energy levels. This is due to the increased energy of electrons in higher energy levels.
Electrons farther from the nucleus are said to be of higher energy levels or higher orbitals. This means they have more energy and are less tightly bound to the nucleus compared to electrons closer to the nucleus.
Protons and neutrons are situated in the nucleus; electrons surround this nucleus. Between the nucleus and clouds of electrons surely is a zone of vacuum; the structure of the atomic nucleus is not exactly known.
The space in which electrons move is huge compared to the space occupied by the atomic nucleus. Electrons are found in electron clouds that extend far beyond the nucleus, making up most of the volume of an atom. The nucleus, where the protons and neutrons are located, is very small in comparison.
Yes. because electrons revolve around the nucleus and have practically negligible mass when compared to the nucleus.
Yes, as electrons get farther from the atomic nucleus they are less attracted to that nucleus, which is exactly what you would expect on the basis of Coulomb's Law, F=q1q2/r2 as the radius of the orbit increases the attractive force becomes decreased.
The first two statement are false. The other one is true. There are electrons outside the nucleus, but they are much lighter than the particles in the nucleus.
Electrons are extremely small compared to neutrons. Electrons have a negative charge and surround the nucleus in a kind of 'cloud'. Neutrons have no charge and are located in the nucleus of an atom.
The valence electrons experience the weakest attraction to the nucleus in an atom. This is because they are the outermost electrons and are furthest from the positively charged nucleus, making their attraction relatively weaker compared to the inner electrons.
You are probably referring to the electrons. It doesn't exactly "circle" the nucleus of an atom, but it does exist in an orbit around the nucleus.
