alkali metals
Group 1 elements
elements of girst group are called alkali metals
The elements in this group are called Alkali Metals.
All elements within a column are called a group.
This is where the name of the table comes from. A horizontal row of elements is called a period. A vertical column is a group.
The most unreactive elements, called the noble gases, are found in the group 8 of the period table.
elements of girst group are called alkali metals
Each (horizontal) row is called a '''period''', whereas each (vertical) column is called a group.
Alkali Metals
The rows going across the periodic table are called periods. As you go across a row, each element increases in number of protons and electrons, which distinguishes it from other elements in the table.

The elements in this group are called Alkali Metals.
The elements in column 18 of a wide form periodic table or Column VIII of a narrow form periodic table, commonly called the noble gases. Also, both elements in the first period, the elements in groups 15, 16, and 17 of the second period, and the element in group 17 of the third period.
All elements within a column are called a group.
This is where the name of the table comes from. A horizontal row of elements is called a period. A vertical column is a group.
The elements located in the first column, group IA on the periodic table, are called alkali metals.
Elements in group 1 are called Alkali Metals, after that group 2 elements are called Alkali Earth Metals, group 3-12 elements are called Transition Elements.
Group 17 elements are called the halogens. Group 18 elements are called the noble gases.
