An expression that identifies the types of numbers of elements present in a compound
chemical formula
What type of molecule has an even distribution of electrical charge?
nonpolar
Which ending is used for a simple binary compound (two elements)?
-ide
A bond formed by the sharing of three pairs of electrons
triple covalent bond
A force that holds atoms together
chemical bond
What is a double covalent bond?
Sharing of two pairs of electrons
What is the difference between -ite and -ate
-ite has fewer oxygen atoms
-ate has more oxygen atoms
A molecule with an uneven distribution of charge
polar molecule
A bond formed by the transfer of electrons between atoms
ionic bond
What is the Octet Rule? Why do atoms follow this rule?
atoms bond in order to achieve eight electrons in their outermost (valence) shell, which provides them with a state of maximum stability
