5
The word ATOM comes from the Greek word for INDIVISIBLE. In what way is this true about atoms?
they cannotbe broken withoutlosing their chemical properties
they cannot be separated once the've bonded to other atoms
they cannot form bonds with other atoms
they cannot gain or lose electrons
6
What do electrons in the same shell have in common?
they are all positively charged
they have the same amount of energy
they are all made up of atoms
they all have neutral charges
7
What contribution did John Dalton make to atomic theory? He discovered that...
atoms had nuclei
every atom was positively charged
atoms could be divided into smaller parts
every element consists of one type of atom
8
To become positively charged, an atom must:
gain a proton
gain an electron
lose a proton
lose an electron
9
The word atom comes from the Greek word "atomos" meaning
atmosphere
indivisible
united
breakable
10
What can you conclude from the fact that scientists continue to update the atomic model?
scientists didn't have any info about atoms until recently
old information about atoms in completely useless
new information about atoms continues to be discovered
scientists still have no idea what atoms look like

that easily lose electrons
that any gases
that have strong electrochemical charges
that do not react with other substances
13
Ernest Rutherford discovered that atoms were mostly:
empty space
positively charged
electrons
negatively charged
14
Where are electrons located in an atom?
the space around the nucleus
they don't exist
with the neutrons
with the protons
15
What are electrons?
positively charged particles
neutrally charged particles
negatively charged particles
uncharged particles
16
What might happen if the strong force didn't exist?
electrons would have positive charges
it would be more difficult to split atoms
neutrons would not exist
atomic nuclei would fly apart
