46. Do Now
List as many elements as you can from the periodic table WITHOUT LOOKING ☺

47. Objectives 1.

48. The
Periodic
Table

50. Dmitri Mendeleev (1869, Russian)
Organized elements by increasing atomic mass.
Elements with similar properties were grouped together.

51. Dmitri Mendeleev (1869, Russian)
Predicted properties of undiscovered elements.

52. Henry Moseley (1913, British)
Organized elements by increasing atomic number.
Resolved discrepancies in Mendeleev’s arrangement.

53. Organization of the Elements

54. Metallic Character
Metals
Nonmetals
Metalloids

55. Get 3 colored pencils. Make a key!

56. Blocks
Main Group Elements
Transition Metals
Inner Transition Metals

57. Periods and Families Periods: horizontal rows on the periodic table
physical and chemical properties change somewhat regularly across a row.
Elements closer to each other in the same period tend to be similar than those that are farther apart.
Groups: vertical rows of elements, AKA families
Each group contains similar chemical properties

59. Do Now: Au Si Br Classify the following as either a
METAL, NON-METAL or METALLOID: Au Si Br

60. METALS : Types of Elements Shiny Conductors of heat and electricity
Most metals are ductile (can be drawn out into a thin wire).
Most metals are malleable (can be pounded into thin sheets like tin foil)
a sugar cube sized chunk of gold can be pounded into a thin sheet which will cover a football field!

61. METALS Continued....
All are solids at room temp (except Mercury, which is liquid)
Metals tend to have low ionization energies, and typically lose electrons (i.e. are oxidized) when they undergo chemical reactions
Alkali metals are always 1+ (lose the electron in s subshell)
Alkaline earth metals are always 2+ (lose both electrons in s subshell)
Compounds of metals with non-metals tend to be ionic in nature.

62. Add in ionization!

63. NON- METALS : Types of Elements Vary greatly in appearance
Non-lustrous
Poor conductors of heat and electricity
The melting points of non-metals are generally lower than metals
Seven non-metals exist under standard conditions as diatomic molecules: H2(g) N2(g) O2(g) F2(g) Cl2(g) Br2(l) I2(l) (volatile liquid - evaporates readily)

64. Nonmetal + Metal -> Salt
NON- METALS continued...
Nonmetals, when reacting with metals, tend to gain electrons (typically attaining noble gas electron configuration) and become anions:
Nonmetal + Metal -> Salt
Compounds composed entirely of nonmetals are molecular substances (not ionic)

65. Metalloids: Types of Elements
Elements may share properties of metals and non-metals.
A stair-step line separates the metals from the nonmetals on the periodic table

66. Metalloids continued... Properties:
All metalloids are solids at room temperature.
Less malleable than metals but not as brittle as nonmetals.
Metalloids tend to be semiconductors of electricity. (intermediate between metals and nonmetals).
Used in semiconducting materials found in computers, calculators, televisions and radios.

67. Noble Gases Types of Elements
Elements in Group 18 of the periodic table.
They are considered nonmetals.
These elements are generally unreactive.
All are gases at room temperature.
Examples: neon, argon, krypton, xenon (all used in lighting) and helium.

68. Do Now: Classify the following as either a:
METAL, NON-METAL or METALLOID: Au Si Br
An element that is brittle and conducts electricity
An element that is malleable
An element that has tendency to become an anion
