Bonding Test Review Sheet Flashcards
(18 cards)
Reactants
compounds that go into a chemical reaction
Covalent Bonds
joint atoms inside a molecule
Chemical Bonds
can be either ionic or covalent
Ions
stay together because atoms that make them up are oppositely charged, behave differently than atoms
Single Bond
occurs when each atom donates only one electron to a bond, more flexible and easy to break
Positive Ions
give up electrons to other atoms
Ionic Bonds
where all electrons are transferred from one atom to another, all salts have them
H2O
a molecular formula
Compound
two or more atoms combined in a certain ratio
Balanced Equation
accounts for all the atoms in a chemical reaction
Products
compounds that are made during a chemical reaction
Octet Rule
states all atoms must have 8 electrons in their outermost energy level
Molecular Formula
tells you the composition of a molecule
Covalent Bonds
when atoms share electrons
Molecular Formula
tells you the composition of a molecule or compound and the arrangement of the atoms
Difference between atom and ion
atoms have no charge, ions have charge
Difference between covalent bond and ionic bond
covalent bonds form when 2 or more atoms share electrons while ionic bonds form when one atom transfers electrons to another atom
Difference between atom and molecule
atom is the building block of matter while a molecule is
