Question 1
Question

Answer
-
Dalton
-
Democritus
-
Rutherford
Question 2
Question
Who discovered the later to be named electron?
Answer
-
J.J Thomas
-
Dalton
-
Bohr
Question 3
Question
What particle did Rutherford shoot at a piece of thin gold foil during his experiment to confirm that an atom is mostly empty space?
Answer
-
Beta particle
-
Soot particle
-
Alpha particle
Question 4
Question
What did Rutherford discover about the atom due to his experiment with firing particles at gold foil?
Answer
-
The atom has a dense positivley charged nucleus in the center of the atom.
-
The atom has electrons which orbit the nucleus in energy levels.
-
Atoms are mostly empty space with negatively charged particles embedded.
Question 5
Question
What of the below evidence supported Bohrs hypothesis that electrons are located at specific energy levels.
Answer
-
Atomic Spectra
-
When compounds are formed
-
Electrolysis of compounds
Question 6
Question
[blank_start]Dalton's[blank_end] Billiard Balls-
Conclusion- Atoms are [blank_start]solid spheres[blank_end]. Atoms are of the same element [blank_start]are identical[blank_end].
Evidence- When observing the formation of [blank_start]compounds[blank_end] and the atom rearrangement.
Answer
-
Dalton's
-
Bohrs
-
Rutherfords
-
Democritus
-
solid spheres
-
Hollow spheres
-
small squares
-
identifiable mass
-
are identical
-
vary slightly
-
are different
-
compounds
-
ions
-
molecules
Question 7
Question
When an electron [blank_start]absorbs energy[blank_end] it is [blank_start]excited[blank_end] to a higher energy level. However the electron is [blank_start]unstable[blank_end] in its [blank_start]excited position[blank_end] so in turn [blank_start]drops to[blank_end] any lower energy level. The electron [blank_start]emits energy[blank_end] in the process in the form of [blank_start]light[blank_end].
Answer
-
absorbs energy
-
steals energy
-
light
-
emits energy
-
unstable
-
excited position
-
drops to
-
excited
