I and II. The Alkaline Earth Metals and the Alkali Metals.
Yes, alkali metals are located in the left-most column of the periodic table, specifically in Group 1. They are highly reactive elements with one electron in their outer shell.
The 1st column from the left
The 1st column from the left
The most reactive metals are in the group 1 of the Periodic Table - the alkali metals.
They are called alkaline earth metals. They are a group of highly reactive metals.
The elements located in the first column, group IA on the periodic table, are called alkali metals.
The alkali metals in group 1 are the most reactive.
Halogens are second from the rightmost column (The Noble Gases) in the periodic table. The Alkali Earth Metals are the second column from the left in the periodic table after the alkali metals.
The halogens (second column from the right
Group 1 (metals) and Group 17 (non-metals).
The column on the far left of the periodic table contains the alkali metals. These elements are highly reactive and have one electron in their outer shell. They include elements such as lithium, sodium, and potassium.
The reactive group of all metals consists of elements located in Group 1 and Group 2 of the periodic table, known as the alkali metals and alkaline earth metals, respectively. These metals are highly reactive due to their tendency to lose electrons and form positive ions.
