Electrons
The space surrounding the nucleus of an atom contains electrons, which are negatively charged particles. These electrons occupy various energy levels or orbitals around the nucleus.
The space around the nucleus of an atom is called the electron cloud. The electron cloud is the space in which the electrons of that atom travel. Compared to the nucleus, the electron cloud is enormous.
An Atom's nucleus contains protons and neutrons. Surrounding them is the electron cloud.
Electrons. These electrons move in orbitals around the nucleus, which is the central part of the atom containing protons and neutrons. The arrangement of these electrons determines the chemical properties of the atom.
The space between the electrons and the nucleus in an atom is filled with empty space and the nucleus contains protons and neutrons.
The atom is composed of two parts, the nucleus, which contains the Protons and neutrons, and is positively charged; and the negative electrons surrounding it.
nucleus the nucleus contains protons (positive) and neutrons (neutral). The nucleus is always the positively charged, dense center of an atom.
an atom has two subatomic particles which are neutrons and protons in the nucleus or "center" and electrons surrounding the nucleus in orbitals, "orbit like" regions of space outside the nucleus.
The electron is most likely to be found in the electron cloud surrounding the nucleus of an atom, rather than inside the nucleus. The nucleus contains protons and neutrons, while electrons are located in the electron orbitals outside the nucleus.
Electron in an atom is represented by electron cloud around the nucleus
The majority of an atom's mass comes from its nucleus, where the protons and neutrons are joined. The electrons of an atom are so distant and so minuscule in size, that their weight is negligible. When calculating the mass of an atom is therefore protons+neutrons.
EMPTY SPACE! Over 99% of an atom is empty space. The nucleus is in the center and contains neutrons and protons and this is where most of the mass of an atom is.
