FINAL JEOPARDY: What is the smallest particle of an element that has all the chemical properties of the element?

An atom

100

Is a theory every discarded? 

No, it's modified.

100

Double jeopardy: 

How many years (rough estimate) did it take for scientists to refine the atomic theory into what we know today?

roughly 2,000 years

100

The number of protons determines what element an atom will be. On the periodic table, this is also known as "the ___________________  _____________"

Atomic number

100

What are the three states of matter and how fast do its particles move?

Solid: Shaking in place

Liquid: flows and takes shape of a container

Gas: Freely moving in all directions

100

I am positively charged and live in the nucleus of the atom.

what's my name?

Proton

200

What is a hypothesis?

A testable statement of what the researcher predicts will be the outcome of a study.

200

All atoms have 3 subatomic particles. Rutherford's model was able to develop a more precise model of the atom we know today. What 2 particles compose the central nucleus?

Proton and Neutron

200

What are the three subatomic particles and their charges?

Proton: +

Electron: -

Neutron: No charge

200

Double Jeopardy: What is the orientation of the particles within each state of matter (aka : if you were to draw 10 particles of each, what would they look like)

Solid: compact

Liquid: fills shape of container, toward bottom

Gas: free flowing

200

What do you find when you add the protons and neutrons together 

Mass number of an element

300

Why are theories modified throughout the years?

Additional scientific knowledge contributes to theories by providing more precise explanations

300

in 1911, Neils Bohr penned the "Bohrs orbit model" showing that electrons orbited the central nucleus. His research allowed Schrodinger to provide more evidence on what we know today as the electron cloud. How did Neils Bohr publishing his research help science?

Communication within the science community helped further the research of the atomic theory by addressing any errors and correcting them.

300

What subatomic particle is responsible for determining the type of element.

Proton

300

What is the attraction between particles in each different state of matter?

Solid: strongly attracted/ Strong bonds

Liquid: Weakly attracted/ Weak bonds

Gas: No bonds

300

What subatomic particle can be shared between separate atoms?

Electron

400

After my experiment, if my hypothesis is disproven, do I erase it and write a new one supported by the evidence?

No. In your conclusion write that your hypothesis has been disproven via the evidence.

400

Why are atoms considered to be the smallest unit of an element?

They are the fundamental building blocks of matter and cannot be divided into smaller bits, and still retain the properties of a given element.

400

a neutral atom must have an equal number of what 2 subatomic particles?

protons and electrons

400

A young scholar, Kelly left butter out on the countertop. She came back 5 hours later and inferred the speed of the molecules within the butter, has sped up. What phase change did she observe?

Solid to Liquid

400

Rutherford found what part of the atom by doing what?

the nucleus, shooting particles through gold foil and some of them bounced back
