Balancing Act
Let's Bond
100

A molecule that has slight positive or negative charges due to an imbalance in the way electrons are shared

What is a polar molecule?

100

THe force of attraction between molecules  of the same substance

What is cohesion?

100

This is a notation indicating the elements in a compound nd the ratios of the atoms of each element

What is a chemical formula?

100

These numbers appear before a formula in a chemical equation to show ow many atoms or molecules are involved

What is a coefficient?

100

A force of attraction between atoms or groups of atoms

What is a chemical bond?

200

This bond occurs when electrons are not shared equally

What is a polar covalent bond?

200

This is responsible for the great majority of water's interesting properties

What is polarity?

200

These are substances that undergo a chemical change

What are reactants?

200

This is when both sides of an equation have the same number of atoms

What is balanced?

200

A chemical bond formed between oppositely charged ions

What is ionic bond?

300

Chemists look at this to help decide if a molecule is polar

What is type of atoms and shapes of molecules?

300

These are easy to dissolve in water due to their polarity

What are ionic compounds?

300

These new susbtances are formed as a result of a chemical change

What are products?

300

When balancing chemical equations one must NEVER change one of these

What is a subscript?

300

Used by scientists to simplify Bohr's model to show what happens in a reaction

What is an electron dot diagram?

400

The name of a molecule when the pull of electrons is equal from both sides

What is a nonpolar molecule?

400

This is the force of attraction between molecules of different substances

What is adhesion?

400

These determine how atomic bonds form or break

What are valence electrons?

400

THis is the first step in balancing a chemical equation

What is count atoms?

400

An atom or a group of atoms that has a positive or negative charge

What is an ion?

500

This is the Greek letter used to indicate which atom has a partial charge in a covalent bond

What is delta?

500

This phenomena occurs when cohesion forms a skin-like boundary on the surface of the water

What is surface tension?

500

This is a representation of a chemical reaction using formulas for reactants and products

What is a chemical equation?

500

This is the basis for balancing chemical equations

What is the Law of Conservation of Mass?

500

Atoms with a positive charge are called positive ions or this

What is a cation?
