Unit 2Chemistry Test Review

What is Matter?Anything that has _______ and _________.

What is Matter?Anything that has mass and volume.

What is the smallest unit of matter?

Hint: not a Chihuahua!

An Atom!

What is the smallest unit of matter?

What is an

?

Hint: It’s not the skateboarding company!

An element is “pure stuff”. It is only one kind of atom in matter such as pure gold (Au)

Other Examples:CarbonHydrogenOxygenNitrogenPhosphorous

What are atoms made up of? What are their charges?

?

What are atoms made up of? What are their charges?

What makes up the Atomic Mass of the atom?

(Larger Number)

What makes up the Atomic Mass of the atom?

Protons +

Neutrons

What does the Atomic Number represent in an atom?

What does the Atomic Number represent in an atom? # of Protons

Also tells how many electrons are present

WHAT IS AN ION?

AN ION IS WHEN AN ATOM HAS GAINED OR LOST ELECTRONS AND

BECOME MORE + OR -

Remember: Ion “I” am greedy! “I” give or take electrons but do not share!

OK, now you know what an ion is, so what is an

Ionic Bond?

“I”onic Bond: When electrons are gained or lost (NO SHARING) between atoms to make a compound.

Hint: “I” am greedy! “I” give or take electrons but do not share!

What is a covalent bond?Hint:

Co-captains share their

position

Atom Atom

Covalent bond: When two atoms share electrons to create a compound.

What are Isotopes?

Isotopes are same element with different numbers of NEUTRONS!

OK…Isotopes are the same element with different numbers

of neutrons.How can I remember that?

I so hope (sounds like Isotope)

Jimmy Neutron doesn’t push the wrong button!

Silly, but you’ll remember it!

Define: Compound

2 or more elements combined chemically

Compound

Chemical and Physical

What type of changes in matter would be considered to be

physical?

What type of changes in matter would

be considered to be chemical?

What does a pH scale indicate (do not say the pH number). It is the concentration of ___?___ in a

solution.

What does a pH scale indicate? (do not say the pH number). It is the concentration of

Hydrogen ions (H+) in a solution.

H+ = OH-

H+ OH- H+

OH-

What is a Buffer?Don’t have a clue?

Hint: We have been dealing with pH, so it probably has something to do with that.

What? It is a weak acid or base

Does? That reacts with strong acid or base

Why? to bring the pH back to neutral (Homeostasis)

Buffer

What is a mixture?

What are the 2 types of mixtures that we talked about?

What is a mixture?When two things are mixed together

PHYSICALLY but can be separated

What are the 2 types of mixtures that we talked about?

SOLUTION = even mixing (salt water) SUSPENSION = won’t stay mixed

(Italian dressing)

Define & Give and Example:

•Solute

•Solvent

•Solution

Solute: What is dissolved by the solvent Ex: SALT

Solvent : What does the dissolvingEx: WATER

Solution: When a solute is dissolved in a solvent Ex: Salt + Water

What is the name for a type of mixture that there is NO DISSOLVING taking place?

Suspension: No Dissolving

Sand + Water

Oil + Vinegar

What is COHESION?

What is ADHESION?

What is COHESION?

What is ADHESION?

Same molecules sticking together Water + Water

Different molecules sticking together Water + Glass

What is the weak bond called that forms between the polar molecules of water?

What is the weak bond called that forms between the polar molecules of water?

H(+)

What is polarity?

See a resemblance?

H(+)

O(-)

H(+)

Polarity: Unequal sharing of electrons

causing (+) on one side and (-) on the other

See a resemblance?
