Draw/explain what the following people(s) models of atoms:
developed the idea of atoms, but
thought they were solid, and different
from each other.
22. Greeks:
agreed atoms were solid,
developed the idea of atomic weights
and symbols for elements
23. John Dalton:
discovered the electron, negative
charge in positive background material,
plum pudding/chocolate chip cookie
24. JJ Thomson:
discovered the nucleus of
atoms and that it was positive, electrons
orbit nucleus, atom mostly empty space
(gold foil)
25. Ernest Rutherford:
electrons orbit in specific paths
called energy levels, planetary model
26. Niels Bohr:
27. Draw/explain model of the atom (called the electron cloud/quantum model):
Electrons move around nucleus in energy
levels (orbitals) so fast, we don’t know
exactly where they are…like a cloud

46. – 47. There are a number of patterns in the periodic table. Name at least one as
you go across the row and at least one as you go down a column.
Across rows:
Atomic # goes up by 1
# protons goes up by 1
# electrons in neutral atom goes up by 1
(skip 3 – 12)
# valence electrons goes up by 1
(skip 3 – 12)
Energy level stays the same
Down column:
Energy levels goes up by 1
Same valence electrons

Hafnium (Hf)_. (name it)
49. The third element in the fourth family is _
Hafnium (Hf)__. (name it)
50. The third element in the fourth period is __

51. – 52. Where, in general, can I find the metals on the periodic table? What are
their characteristics?
Left hand side and middle
Give away electrons, form positive ions,
good conductors of heat and electricity,
ductile, malleable, solid at room temp. (
1 liq., 0 gas)
53. – 54. Where, in general, can I find the nonmetals on the periodic table? What are
their characteristics?
Right hand side
Take electrons, form negitive ions,
good insulators of heat and electricity,
most are gas at room temp. (4 solid, 1
liq.)
55. – 56. Where, in general, can I find the metalloids (semiconductors) on the periodic
table? What are their characteristics?
Between the other two…stair step line
Properties in between…semiconductors. All
are solid at room temp.
