This is formed when two or more atoms combine molecule
Depicts the numbers and kinds of atoms in a molecule molecular formula
Shows how atoms bond and are arranged in a molecule structural formula
The region of space electrons occupy one or more of electron shells (energy shells)
This is when the outer shell attempts to be filled to 8 electrons octet rule
Cannot form chemical bonds inert
Electron in the outer shell of atom that can combine with other atoms to form molecules valence electrons
Atoms that are not reactive and have completely full outermost electron shells inert atoms
Atoms that gain or lose electrons and become electrically charged ions
Atoms that become positively charged because they lost electrons cations
Atoms that become negatively charged because they gain electrons anions
Bond formed between two opposite charged ions (between an anion and cation) ionic bonds
Formed when atoms share electron in an attempt to fill the outer shell covalent bond
Specialized molecule in which electrons are not shared equally polar
Formed by the attraction of a positive hydrogen end of a polar molecule to the negative nitrogen or oxygen end of another polar molecule hydrogen bond
Substances being changed in a chemical reaction reactants
Substances formed at the end of a chemical reaction products
Occurs when two or more atoms, ions, or molecules bond to form a more complex structure synthesis reaction
