Valence shell
The outer-most shell of an atom is called the valence shell. It is involved in forming chemical bonds with other atoms.
Protons and neutrons form the nucleus of an atom while electrons form the shell of an atom. The electrons in the shell of the atom exist in distinct layers. Those in the outer layer take part in chemical reactions and are involved in electricity. Electrons are also basic particles called leptons. Protons and Neutrons are not basic particles but are composite particles called haldrons. They consist of three basic particles called quarks. Quarks are a basic particle called fermions.
Valence
An atom's outer electron shell is made of electrons. These electrons are negatively charged particles that occupy energy levels around the nucleus of the atom. The number of electrons in the outer shell determines the atom's chemical properties and how it interacts with other atoms.
The negatively charged particles of an atom are in an outer shell.
Valence shell
The outer-most shell of an atom is called the valence shell. It is involved in forming chemical bonds with other atoms.
the shell
An egg with an outer hard shell is called the cuticle or bloom. It helps keep out bacteria and dust.
It is a shell, as in a cockle shell or oyster shell.
the shell
The outer shell of a watermelon is called the rind or peel. It is the tough outer layer that is typically green in color and protects the fruit inside.
The outer layer of a sea shell is called the exoskeleton or the shell's outer casing. It is composed of calcium carbonate and provides protection for the soft tissues of the animal inside.
Valence shell and Ultimate Shell
The outer shell of a plane is called the fuselage. It is the main body of the aircraft that houses the cockpit, passenger cabin, and cargo hold.
The outer shell of an atom is called the valence shell. It contains the valence electrons, which are involved in forming chemical bonds with other atoms.
