Bonding

What is compound

• a substance made from two or more different elements that have been chemically combined

• atoms with either a positive (+) or negative (-) electrical charge

• Atoms that lose electrons and have a posative charge

• Atoms that gain electrons and have a negative charge

what is chemical formula

• the relative numbers of atoms of each kind of chemical compound by using atomic symbols and numerical subscripts.

• a chemical compound whose simplest units are molecules.

• Bonds between a metal and nonmetal where electrons are GAINED or LOST.

• Atoms want to have 8 electrons in their outer shell to be stable, except hydrogen which only wants 2.

Octet rule

• Atoms want to have 8 electrons in their outer shell to be stable

• Bonds between a metal and nonmetal where electrons are GAINED or LOST.

• a chemical compound whose simplest units are molecules.

• a molecule containing only two atoms

Chemical bond

• Electrons found in the outermost shell. They are the electrons involved in bonding.

• a bond formed between two or more metals

• a mutual electrical attraction between the nuclei and valence electrons of different atoms that binds the atoms together

• Bonds between a nonmetal and metal where electrons are SHARED.

Ionic Bond

• The outermost shell of an tom

• Bonds between a metal and nonmetal where electrons are GAINED or LOST.

• Bonds between a nonmetal and nonmetal where electrons are SHARED.

• The charge on an atom after electrons are gained or lost.

Ions

• Atoms that lose electrons and have a postive charge

• atoms with either a positive (+) or negative (-) electrical charge

• Atoms that gain electrons and have a negative charge

Oxidation Number

• Atoms want to have 8 electrons in their outer shell to be stable, except hydrogen which only wants 2.

• Electrons found in the outermost shell. They are the electrons involved in bonding.

• The charge on an atom after electrons are gained or lost.

polyatomic ion

• an ion composed of two or more atoms

• Atoms that gain electrons and have a negative charge

Covalent bond

• The charge on an atom after electrons are gained or lost

• Bonds between a nonmetal and nonmetal where electrons are SHARED.

• Atoms want to have 8 electrons in their outer shell to be stable

Molecule

• Atoms that lose electrons and have a postive charge

• a mutual group of atoms that are held together by covalent bonds

• a bond formed between two or more metals
