An atom will not normally form a chemical bond if it has how many valence electrons?
An atom will not normally form a chemical bond if it has 8 electrons already or in the case of hydrogen and helium, 2 electrons. A "full" valence shell has 8 electrons starting and period 2 on the Periodic Table. The elements with full valence levels are the elements on the far right family called the noble gases. The noble gases are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn).
An atom will not normally form a chemical bond if it has eight valence electrons, which is a stable configuration known as the octet rule. Atoms with full valence shells are generally unreactive.

What part of the atom do valence electrons occur in?
Valence electrons occur in the outermost energy level, or valence shell, of an atom. These electrons are involved in the formation of chemical bonds and determining the atom's reactivity and chemical properties.
What is an electron called in the outermost energy level?
They are called valence electrons, and they are responsible for an atom's chemical properties. During a chemical reaction, the valence electrons are the only part of an atom that participates.
What is important about the valence electrons?
When an atom undergoes chemical change, only the outermost (valence electrons) are involved.
What are valence shells?
Electrons in the outermost orbitals of an atom. They determine the chemical reactivity of an atom and are the primary electrons that participate in chemical reactions.
What part of an atom is use in a chemical reaction?
Electrons - the valence electrons

What are valence electrons and where can they be found?
Valence electrons are the outermost electrons in an atom that participate in chemical bonding. They are found in the highest energy level (shell) of an atom. The number of valence electrons can determine an element's reactivity and the types of chemical bonds it can form.
An electron in the outermost energy level of an atom is a?
valence electron, which is involved in the atom's chemical reactions and determines its chemical properties.
What re valence electrons?
Valence electrons are the electrons in the outermost energy level of an atom. These electrons are involved in forming chemical bonds with other atoms to make molecules. The number of valence electrons influences the chemical properties of an element.
What best describes a valence electrons?
Valence electrons are the outermost electrons in an atom that are involved in forming chemical bonds with other atoms. They determine the atom's reactivity and ability to form compounds. The number of valence electrons can also be used to predict an element's chemical properties.
Are atom properties determined by the size of the valence electrons?
Atom properties are largely determined by the number and arrangement of valence electrons, rather than just their size. Valence electrons are involved in forming chemical bonds and determining an atom's reactivity and chemical properties. The size of the valence electrons can affect the atom's ability to bond with other atoms but is not the sole determinant of its properties.
