Element 'Y' has electronic configuration 2, 8, 18, 32, 18, 8, 1. To which period and group does 'Y'
belong? State with proper reasoning
NO SPAMMING
sanya55:
and here valence electrons are 1 so the group number should be also equal to one
yaa ..got it
okk
thanks you so much
and the period = number of shells it has
yaa got it thank u so much
it has seven shells so period =7
wlcm:-)
thanks once again :)
:-)

Heya!!Here is your answer friend ⤵⤵
➡The given element is Francium .
↗Group number can be calculated as -
↔If the number of valence electrons are 1-2 then group number = number of valence electrons that is either 1 or 2.
↔But in case it is more than 2 then we add 10 to the valence electrons to obtain group number .
➡Here valence electrons are 1
So group number =1
↔↔↔↔↔↔↔↔↔↔↔↔↔↔↔↔↔↔
➡Period = the period of an element is the number of shells it has . Here the element has 7 shells. So period number =7

Hope it helps you ✌✌
