one answer i know is shell the electron whiz around the centre of atoms are shells
three dimensional arrangement of atoms electron-group geometry
The spatial arrangement of electron groups around the central atom is called molecular geometry. It describes the three-dimensional arrangement of atoms in a molecule.
Atoms that have lost or gained electron(s) are called ions. If they are positively charged (lost an electron(s)), they are called cations. If they are negatively charged (gained an electron(s), they are called anions.
The tiny very dense body located in the atom's center is called the atomic nucleus. It contains protons and neutrons, which make up the majority of the atom's mass. Electrons orbit around the nucleus in the electron cloud.
The protons and neutrons are located in the nucleus of the atom. The nucleus is located in the center of the atom. The nucleus is surrounded by what is called the electron cloud.
The electron cloud.
This is the particle in an orbital in the space around the atoms nucleus and it is called an electron.
Electrons orbit the nucleus of an atom in specific energy levels called electron shells. These negatively charged particles move rapidly around the nucleus, creating a cloud of negative charge that surrounds the center of the atom.
The atoms sharing the electron pairs will spread out around the central atom.
The atoms sharing the electron pairs will spread out around the central atom.
The atoms sharing the electron pairs will spread out around the central atom.
