bcoz these elements accrding to e configuration come in s sub shells
Groups 1 and 2 make up the s-block.
The first block on the periodic table is called the S block.
s block and especially group 1 elements.
Group 1A and 2A, or Alkali metal and Alkaline earth metal.
alkali metals / s block elements
The Alkali Metals are the first column of the periodic table, except for Hydrogen.
The first block on the periodic table is called the S block.
On a periodic table, the "s-block" is the first columns. The elements in the first column have 1 s-electron, and those in the second have 2.
s block and especially group 1 elements.
Group 1A and 2A, or Alkali metal and Alkaline earth metal.
alkali metals / s block elements
The Alkali Metals are the first column of the periodic table, except for Hydrogen.
the s-block, the p-block, the d-block, the f-block,and there is an theoratical g-block
The elements in Groups 1 and 2 are in the s block. The elements in Groups 13-18 are in the p block.
A. s and p block B. p and d block C. f and p block D. d and f block

In the periodic table elements having valence electrons in the same orbital are said to be placed in the same block.There are four blocks in the periodic table s, p, d and f.
