The simple answer is that the s block can contain 2 electrons, the p block 6 electrons, the d block 10 electrons and the f block 14 electrons. Because of this, there are 14 different outer electron configurations and hence it spans 14 groups.
The the electron configurations of elements in Groups 1 and 2 end in the s sublevel.
Magnesium, for example, is a Group 2 element and has an electron configuration of :
1s22s22p63s2
The last electron of the configuration ends in the s-block.
the s orbitals hold 2 electrons at most so the s block spans two groups.
The block of elements that we happen to label 'd' all contain electrons in the 'd' sheel, which can hold a maximum of 10 electrons.
The s orbital in quantum and wave mechanics can only have 2 eelctrons in it. The groups 1 and 2 have either one or two outer electrons and thus in the s block
S shell can have only 2 electrons. P sub shell can have 6 electrons.
it is because s block elements contains s orbitals which can accomodate only 2 electrons which makes it have a general configuration ns2
Because an s orbital can hold 2 electrons. The alkali metals group 1 have 1 s electron. The alkaline earth metals, group 2, have 2.

S-BLOCK IS FROM GROUP # 1-2 P-BLOCK IS FROM GORUP # 13-18 S-BLOCK IS FROM GROUP # 1-2 and P-BLOCK IS FROM GORUP # 13-18
s-block elements: groups 1 and 2 p-block elements: groups 13 to 18
s block elements: groups 1-2 d block elements: groups 3-12 p block elements: groups 13-18
S block elements are elements that contain their outermost electron in the s shell. S block elements are further divided into 2 groups.
The s, p, d, f block realte to the filling of the outer shell orbitals. Group 1 and 2 are the s block. Groups 13-18 the p block, the transition metals the d block and the lanthanides and actinides the f block.
The elements in Groups 1 and 2 are in the s block. The elements in Groups 13-18 are in the p block.
S-BLOCK IS FROM GROUP # 1-2 P-BLOCK IS FROM GORUP # 13-18 S-BLOCK IS FROM GROUP # 1-2 and P-BLOCK IS FROM GORUP # 13-18
The s-block contains group 1-2.
s-block elements: groups 1 and 2 p-block elements: groups 13 to 18
s-block: groups 1 and 2 p-block: groups 13 - 18 d-block: groups 3 - 12 f-block: lanthanides and actinides
s-block elements: groups 1 and 2 p-block elements: groups 13 to 18
s-block elements: groups 1 and 2 p-block elements: groups 13 to 18
s block elements: groups 1-2 d block elements: groups 3-12 p block elements: groups 13-18
S block elements are elements that contain their outermost electron in the s shell. S block elements are further divided into 2 groups.
Group 1 and group 2 elements are called s-block elements
S block has the most reactive elements. The groups 1 and 2 belongs to the s block.
bcoz these elements accrding to e configuration come in s sub shells
