Atomic Structure Overview

What are the 3 parts of an atom?

What does the atomic number represent?

# of protons = ?

what is an isotope?

what is an ion?

? + ? = atomic mass

atomic mass is the ? of different isotopes

what is atomic mass measured in?

proton
(charge, mass, location)

neutron
(charge, mass, location)

electron
(charge, mass, location)

? - ? = # of neutrons

how many electrons can each energy level / orbital hold?

what would make an element stable?

what is ionic bonding?

what are valence electrons?

what is an atoms' valence?

if Lithium and Chlorine ionically bond, who is more likely to donate its electrons?
(Li has a valence of 1 and Cl a valence of 7)

what is covalent bonding?

is the element described on the periodic table an isotope of that element?

what was Democritus' theory?

what did Democritus get wrong?
what did he get right?

what did Plato and Aristotle theorize?
were they even slightly correct?

what was Dalton's theory?
did he get anything wrong?

what did J. J. Thompson theorize?

what did J. J. Thompson get wrong?
what did he get right?

what did Earnest Rutherford discover?

how did Rutherford discover open space + the proton + the neutron?
what did he conclude from this experiment?

did Rutherford get anything wrong?

what was the Bhor model?
what was right? what was wrong?

what differs the wave model?

what does the staircase on the periodic table divide?

what do the "groups" on the periodic table indicate? where are they located?

what do the numbers on the side of the table indicate?
