THe force of attraction between molecules of the same substance
What is cohesion?
This is a notation indicating the elements in a compound nd the ratios of the atoms of each element
What is a chemical formula?
These numbers appear before a formula in a chemical equation to show ow many atoms or molecules are involved
What is a coefficient?
A force of attraction between atoms or groups of atoms
What is a chemical bond?
This bond occurs when electrons are not shared equally
What is a polar covalent bond?
This is responsible for the great majority of water's interesting properties
What is polarity?
These are substances that undergo a chemical change
What are reactants?
This is when both sides of an equation have the same number of atoms
What is balanced?
A chemical bond formed between oppositely charged ions
What is ionic bond?
Chemists look at this to help decide if a molecule is polar
What is type of atoms and shapes of molecules?
These are easy to dissolve in water due to their polarity
What are ionic compounds?
These new susbtances are formed as a result of a chemical change
What are products?

Used by scientists to simplify Bohr's model to show what happens in a reaction
What is an electron dot diagram?
The name of a molecule when the pull of electrons is equal from both sides
What is a nonpolar molecule?
This is the force of attraction between molecules of different substances
What is adhesion?
These determine how atomic bonds form or break

THis is the first step in balancing a chemical equation
What is count atoms?
An atom or a group of atoms that has a positive or negative charge
What is an ion?
This is the Greek letter used to indicate which atom has a partial charge in a covalent bond
What is delta?
This phenomena occurs when cohesion forms a skin-like boundary on the surface of the water
What is surface tension?
This is a representation of a chemical reaction using formulas for reactants and products
What is a chemical equation?
This is the basis for balancing chemical equations
What is the Law of Conservation of Mass?
Atoms with a positive charge are called positive ions or this
