How do scientists know how atoms are structured?

By running experiments that expose their properties

By looking at them under a microscope

By examining only the largest atoms

What can you conclude from the fact that scientists continue to update the atomic model?

New information about atoms continues to be discovered

Old information about atoms is completely useless

Scientists did not have any information about atoms until a few years ago

Scientists still have no idea what atoms look like

What contribution did John Dalton make to atomic theory?

He discovered that every element consisted of one type of atom

He discovered that every atom was positively charged

He discovered that atoms had nuclei

He discovered that atoms could be divided into smaller parts

The majority of an atom's mass exists where?

In the space between the nucleus and the electrons

How are neutrons different from protons and electrons?

They are more massive than protons and electrons

They are less massive than protons and electrons

Protons and electrons exist in atomic nuclei; neutrons orbit the nucleus in a "cloud"

What is the significance of the periodic table of elements? Choose the best answer.

It predicts and lists all the chemical elements in the universe

It lists all the different metals known to humans

It explains where different atoms can be found

It proves that atoms are the building blocks of matter

What do electrons in the same shell have in common?

They have the same amount of energy

They are all positively charged

What might happen if the strong force didn't exist?

Electrons would have positive charges

It would be more difficult to split atoms

Oxygen has an atomic number of 8. What can you conclude from this fact?

An atom of oxygen has 8 protons

An atom of oxygen weighs 8 grams

An atom of oxygen has 4 protons and 4 electrons

An atom of oxygen has 8 positrons

The word "atom" comes from a Greek word for "indivisible." In what way are atoms indivisible?

They cannot be broken apart without losing their chemical properties

They cannot be separated once they've bonded with other atoms

They cannot form bonds with other atoms

They cannot gain or lose electrons

How are molecules different from atoms?

They consist of several atoms bonded together

Their particles do not have electrical charges

What can you conclude from the fact that electrons orbit far away from atomic nuclei?

Atoms are comprised mostly of empty space

Atoms consist of subatomic particles

Fluorine has an atomic number of 9. What can you conclude about an atom of fluorine from this fact?

It has a boiling point of 9 degrees Celsius

Since atoms are very small, what can you infer about atomic mass units?

One atomic mass unit is much lighter than a gram

One atomic mass unit is equivalent to a gram

One atomic mass unit is much heavier than a gram

Atomic mass units and grams measure different properties

On the periodic table, how is atomic mass represented?

As an average of the mass of different isotopes

As the exact mass of every atom

As the mass of the most common isotope

As the masses of all the protons added together

What do carbon-12 and carbon-14 have in common?

They have the same number of protons

They have the same number of neutrons

They have the same atomic weight

How is carbon-12 different from carbon-14?

They have a different number of neutrons

They have a different number of protons

They have a different number of electrons
