Elements in the Table • The elements in the periodic table are positioned in increasing order of their Atomic Number (Z), and NOT based on their Atomic Mass (A). • This is known as The Periodic Law. • In order to understand the periodic table, we must remember that electrons are located in levels of energy, and in probabilistic regions called orbitals. • The orbitals are: s : holding a maximum of 2 electrons. p : holding a maximum of 6 electrons. d : holding a maximum of 10 electrons. f : holding a maximum of 14 electrons.

Reading the Periodic Table Each element is identified by a chemical symbol • Each square on the periodic table includes an element’s name, chemical symbol, atomic number, and atomic mass. • The names of the elements come from very different sources. • Some element names vary by country, but the chemical symbols are the same worldwide. • For most elements, the chemical symbol has one or two letters, the first letter is always capitalized, the other(s) letter(s) are lowercase. • The newest elelments have temporary three‐letter symbols.

Rows are called Periods • Each horizontal row of elements (from left to right) on the periodic table is called a Period. • The physical and chemical properties of elements in a row follow a repeating, or periodic, pattern as you move across the period • Properties like conductivity and reactivity change (increase) gradually from left to right in each period.
11
12
Columns are called Groups • Each vertical column of elements (from top to bottom) on the periodic table is called a Group. • Elements in the same group often have similar chemical and physical properties . • For this reason, a group is also called a family.

Classes of Elements • Elements are classified as metals, nonmetals, and metalloids (poor metals), according to their properties. • The number of electrons (e‐) in the last energy level of an atom is one characteristic that helps determine which category an element belongs in. • The zigzag line in the table determines which elements are metals, nonmetals and metalloids.

Teacher's Notes This class has been designed to cover the topics of Groups and Periods from Monday June 8th till Friday June 12th. For further knowledge about this topic: 1. Conduct a thorough search under the topic: Groups and Periods on the Web, books and magazines. 2. If findings are not specific, ask your teacher for suggestions.
