Pattern of Valence Electrons Group 1 has 1 valence electron. Group 2 has 2 valence electrons. Group 13 has 3 valence electrons. Group 14 has 4 valence electrons. Group 15 has 5 valence electrons. Group 16 has 6 valence electrons. Group 17 has 7 valence electrons. Group 18 has 8 valence electrons.

The electrons that are in the outermost energy levels are called the valence electrons. If an atom absorbs energy such as heat or light, the electrons can become excited and jump up to other orbitals. When this happens the atom is said to be in an excited state.

The nucleus, with its four protons and five neutrons, is surrounded by a cloud of electrons. In 1911, Ernest Rutherford discovered that at the core of every atom is a nucleus. Atomic nuclei consist of electrically positive protons and electrically neutral neutrons.

Valence electrons are the electrons in the outermost shell, or energy level, of an atom. For example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell. We can write the configuration of oxygen's valence electrons as 2s²2p⁴.

The protons and neutrons are found in the middle of the atom in the nucleus. Meanwhile, the electrons are found on the outer shell of the atom.

Electrons: Negatively charged subatomic particles found in the electron shells surrounding the nucleus. Nucleus: The region located in the center of an atom, containing both protons and neutrons. Electron Shells: The region located on the outermost area of the atom only containing electrons.

7 Valence electrons, often : OCTET An atom's valence is the number of electrons that it loses, adds or shares when bonding with other atoms.

Core electrons are the electrons in an atom that are not valence electrons and do not participate in chemical bonding. The nucleus and the core electrons of an atom form the atomic core.
