Which of the following option (s) is/are correct?

Options

A. `|/_\H_(1)|gt|/_\H_(2)|`
B. `|/_\H_(4)|gt|/_\H_(3)|`
C. `|/_\H_(5)|gt|/_\H_(6)|`
D. `/_\H_(7)` is +ve

Answer

A, B, C, D

Explanation

`O_((g))+e^(-)toO_((g))^(-) /_\H=-ve`
`O_(g)^(-)+e^(-)toO_((g))^(-2) /_\H=-ve`
`O_((g))+2e^(-)toO_((g))^(-2) /_\H=+ve`
`O_(2(g))toO_(2(g))^(+)+e^(-)` (Electron removed from `pi^(*) 2P_(y)` or `pi^(*) 2P_(x)`)
`O_((g))toO_((g))^(+)+e^(-)` (Electron removed from `2P`)
`H_(2(g))to H_(2(g))^(+)+e^(-)` (Electron removed from `sigma1s`)
`H_((g))toH_((g))^(+)+e^(-)` (Electron removed from `1s`)
