Activity of Metals
The most active metals are so reactive that they readily combine with the O 2 and H 2 O vapor in the atmosphere and are therefore stored under an inert liquid, such as mineral oil. These metals are found exclusively in Groups IA and IIA of the periodic table. Metals in the second class are slightly less active.

1.2: A First Look at the Periodic Table
The periodic table is not simply a grid of elements arranged numerically. In the periodic table, the elements are arranged in horizontal rows called periods, and into vertical columns called groups. These groups are numbered by two, somewhat conflicting, schemes. In the simplest presentation, favored by the International Union of Pure and ...

Periodic Table Trends- Atomic size, Melting & Boiling Point Trend
We observe a common trend in properties as we move across a period from left to right or down the group. This trend in properties is known as periodic properties. The important periodic properties are atomic size, metallic character, non-metallic character, ionization potential, electron affinity, and electronegativity. Periodic Table Trends.

Main Group Elements
The main group elements are groups 1, 2, and 13-18 on the periodic table. The main group elements are the chemical elements belonging to the s-block and p-block on the periodic table. These are elements in group 1 and group 2 (s-block) and groups 13 through 18 (p-block). In older IUPAC group numbering systems, the main group …

Element Families on the Periodic Table
An element group is a column of elements on the periodic table. There are 18 element groups, which appear on the periodic table as numbers listed above the element columns. For example, the first column is group 1, I, or IA, depending on the numbering system. For the most part, element families and element groups are the same thing.
