$X$ $ = 1{s^2},\,\,2{s^2}2{p^6},\,\,3{s^2}3{p^6},\,\,4{s^2}$
અને $Y$ $ = 1{s^2},\,\,2{s^2}2{p^6},\,\,3{s^2}3{p^5}$
તો $X$ અને $Y$ બને મળીને નીચેના પૈકી ક્યુ સંયોજન બનાવશે
\(X =1 s ^2\, 2 s ^2\, 2 p ^6\, 3 s ^2 \,3 p ^6\, 4 s ^2\) has \(2\) electrons more than stable configuration. So this can be written as \(X ^{2+}\)
after removing \(2\) eletrcons.
Electronic configuration of \(Y\) is:
\(Y=1 s^2\, 2 s^2\, 2 p^6\, 3 s^2 \,3 p^5\) has \(1\) electron less than stable configuration. So this can be written as \(Y ^{-}\)
after gaining \(1\) electron
\(X ^{2+}+2 Y ^{-}= XY _2\)
\(2\) ions of element \(Y\) combine with \(1\) ion \(X\) to give \(XY _2\).
The resulting molecule will be stable and will have no net charge.
$KK\left[ {\sigma 2{s^2}{\sigma ^*}2{s^2}\pi 2p_x^2\pi 2p_y^2\sigma 2p_z^2} \right]$ તો બંધ ક્રમાંક નીચેનામાંથી ક્યો હશે?
