the s block contains the alkali metals
the s block
Metals are on the left side in periodic table. They are mainly present in group-1,2,13. Group-1 is alkali metals and group-2 is alkaline earth metals.Group 1 contains alkaline metals. Group 2 contains alkaline earth metals. And d block also contains metals.
Apart from Hydrogen, Helium and Beryllium; non metals are located in the p-block. Starting from the third period with addition of Li, all of s-block elements are metals. The d-block elements are a compete set of metals.
alkali metals / s block elements
Alkali metals belong to Group 1 of the periodic table. They are highly reactive and readily lose their outermost electron to form positive ions. Alkali metals have low melting and boiling points. They are soft and can be easily cut with a knife. Alkali metals include elements such as lithium, sodium, and potassium.
Metals are located to the left of the stair-step line on the periodic table.

Francium is in the group 1 of the periodic table (alkali metals).
alkali metals / s block elements
All the elements in the d block are metals. Elements in the groups 1 and 2 are also metals. The p block contains metals, non metals and metalloids.

Metals are located to the left of the stair-step line on the periodic table.
The right side of periodic table has non metals and noble elements. Non metals gain electrons. Noble elements are inert in nature.In the right side of the periodic table, there are the p block elements. The p block contains non metals. It has elements of solid, gas and liquid states.The rightmost elements are the noble gases, group 18. Next in the right are the non metals. Group 17 elements are also known as halogens (salt makers).
Alkali metals are in the s and p block of elemnts. The alkali metals are group 1 the s and p block incudes groups 1,2,13,14,15,16,17.
They have a electron of last energy level. so they are in the s block.
The third group in the periodic table has the highest number of elements. It includes 32 elements because the f-block is also included in it.
S block elements- valence electrons are filling the s orbitals D block elements- valence electrons are filling the d orbitals P block elements- valence electrons are filling the p orbitals F block elements- valence electrons are filling the f orbitals
