What are Valence Electrons?
an electron that is found in the outermost shell of an atom and that determines the atom's chemical properties and allow bonding.
How are Valence Electrons Formed?
A valence electron is an electron that is in the hightest occupied energy level of an atom. Atoms can combine to achieve an octet of valence electrons by sharing electrons.
chemical bond is the force that holds atoms or ions together as a unit.
An ionic bond is the force that holds cations and anions together. An ionic bond forms when electrons are transferred from one atom to another.
Ionic compounds are formed between what types of elements?
Valence electrons of atoms are given or taken in order to form an Ionic bond.Positive or negative attraction. Metal and nonmetals. Compounds that contain ionic bonds are ionic compounds.
is a chemical bond in which two atoms share a pair of valence electrons. When two atoms share one pair of electrons , the bond is called a single bond.
Covalent compounds are formed between what type of elelments and How are they formed?
Valence electrons are shared between atoms non metal to nonmetal. (metalloids)
What is a lone pair?
A pair of unshared valence electrons that are not involved in bonding in a molecule
A molecule formed from covalent bonding between two atoms of the same element.
