What are groups known as on the periodic table?

In chemistry, a group (also known as a family) is a column of elements in the periodic table of the chemical elements. There are 18 numbered groups in the periodic table; the f-block columns (between groups 2 and 3) are not numbered. Groups may also be identified using their topmost element, or have a specific name.

What are elements in group 2 called?

Group 2A — The Alkaline Earth Metals. Group 2A (or IIA) of the periodic table are the alkaline earth metals: beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).

What are the following groups known as Group 1?

Group 1 is known as the alkali metals.

What is the other name for the Group 1 elements Why are they called so?

Group 1 elements are called alkali metals because their oxides are soluble in water and group 2 elements are called alkaline earth metals as their oxides form in the earth and are water soluble.

What is the common name given to the element of group 1 Why?

Group 1 elements form alkaline solutions when they react with water, which is why they are called alkali metals.

  • What do the groups tell you on the periodic table?

    Groups and periods are two ways of categorizing elements in the periodic table. Periods are horizontal rows (across) the periodic table, while groups are vertical columns (down) the table. Atomic number increases as you move down a group or across a period. Elements in a group share a common number of valence electrons.
