200

What are the three subatomic particles of an atom?

protons, neutrons, electrons

200

What is the ideal gas law?

(P1V1)/(T1) = (P2V2)/(T2)

200

Which period is Sodium in?

Period 3

400

These are the two types of pure substances

Elements and Compounds

400

Which heat equation would you use for a question that involves changing temperature?

q = mcΔT

400

Define isotope

An isotope of an atom has the SAME number of protons and a different number of neutrons.

400

Which decay particle has the largest mass?

alpha particles

400
How many groups are there on the Periodic Table?

18

600

Evaporation is a type of ____________ change

Physical change

600

Explain what happens to the kinetic energy as a phase change is happening.

Kinetic energy stays the same

600

What are the Rutherford Gold Foil Experiment's two conclusions.

Discovered that the atom was mostly empty space and had a small, dense, positive center called the nucleus.

600

If the temperature of a gas increases, what happens to its volume?

It also increases. 

600

Across a period (left to right), what trend is seen in electronegativity

It increases 

800

This is an example of a _______________________.

Heterogeneous mixture

800

Which heat constant would you use when calculating the heat for a condensation of water vapor to liquid water?

Heat of vaporization.

800

DOUBLE POINTS!

What happens when an atom:
1. gains a neutron

2. gains an electron

3. gains a proton

1. forms an isotope

2. forms an anion

3. forms a new element

800
What fraction of a radioisotope remains after 10 days if its half-life is 2 days. 

1/32

800
Explain why non-metals have high ionization energy

Non-metals prefer to hold on to their valence electrons

1000

Explain the difference between a compound and a mixture.

A compound is a substance that is formed when two elements chemically combine in a fixed ratio.

A mixture is formed when substances are physically combined in variable ratios.

1000

Describe the difference between potential and kinetic energy in a heat curve.

Kinetic energy changes while in one phase of matter, but remains constant during a phase change.

Potential energy remains the same during one phase of matter but changes during a phase change.

1000

What information does the Bohr model of the atom tell us?

The number of protons and neutrons, as well as the number of electrons and how they are distributed

1000

Describe the process of nuclear fusion and where it naturally occurs.

When two smaller nuclei combine to form a larger nucleus and produce a lot of energy. It occurs in the sun

1000

Explain in terms of electron shells why atomic radius increases as you go down a group

Each new shell is further away from the nucleus. This increased distance means that the outermost electrons are located farther from the nucleus.
