Periodic Table:Metals – Located to the left side of the stair-step line (all are solids)

Nonmetals– Located to the right side (can be solids, liquids, or gases).

Metalloids: Located between metals & nonmetals (on the border of the stair-step line)

Metals, Nonmetals, and Metalloids

12

Metals: (to the left)

1) Solids at room temperature2) Shiny, can be converted into wires & sheets.3) High melting & boiling points.4) Good conductors of electricity & heat.

Non metals:(To the right)1) Solids, liquids, or gases at room temp.2) Low melting & boiling points.3) They are brittle & poor conductors of electricity & heat.

Metalloids:•They have properties of both metals & non metals.

Periodic Table:Groups: Vertical columns (elements in the same group have similar properties).Group 1A: The most reactive metals (Alkali metals).Group 2A : Reactive metals also (Alkaline Earth metals).Group 7A: The most reactive non metals (Halogens).Group 8A: Unreactive. Very stables. (Noble gases).

Periodic Table:

Groups-A number = # of valence electrons

Ex.Elements in group 1A – contain 1 valence e-

Elements in group 3A – contain 3 valence e-

Elements in group 7A – contain 7 valence e-

Periodic Table:Periods: Are the horizontal rows on the Periodic Table.All elements in the same period contain the same number of energy levels.

The elements increases by one proton & one electron as you go from left to right in a period.Then, the number of valence electrons increases by one across a period.

Periodic Table:The Periodic Table is divided into four different blocks:1) s-block: Group 1A & 2A, the valence electrons occupy only “s” orbitals. Ex. Na 1s2 2s2 2p6 3s1

Ca 1s2 2s2 2p6 3s2 3p6 4s2 Because there is only one “s” orbital holding up to a maximum of 2 electrons, this block contains 2 columns or groups.

Periodic Table:2) p-block: Group 3A - 8A, the outermost electron occupy “p” orbitals. Ex. B-1s2 2s2 2p1

Ar-[Ne] 3s2 3p6

Br-[Ar] 4s2 3d10 4p5 3 p orbitals (6 electrons) this block contains 6 columns or groups.

Periodic Table:

s-block

Representative or group A elements

p-block

Periodic Table:3) d-block: Groups B, the transition metals, they have a filled outermost s orbital & partially filled or filled d orbitals in energy level (n-1). Ex. Sc- [Ar] 4s2 3d1

Cd- [Kr] 5s2 4d10 5 ”d” orbitals (10 electrons) this block contains 10 columns or groups.

Periodic Table:4) f-block: The inner transition metals, the outermost electron is placed in “f” orbitals. Ex. Ce-[Xe] 6s2 4f2

Np- [Rn] 7s2 5f5 7 “f” orbitals (14 electrons) this block contains 14 columns or groups.
