Why chromium lose 1st e from 4s instead of 3d...?? |
|
Answer» Because half filled shells are more stable than another one 4s² $$\\boxed{↑\\↓}$$ 3d⁴ $$\\boxed{↑\\ \\|\\↑\\ \\|\\ ↑\\ \\|\\↑\\ \\| \\ \\}$$ hear 4s is full filled so it is stable but 3d is not stable 4s¹ $$\\boxed{↑\\ }$$ 3d⁵ $$\\boxed{↑\\ \\|\\↑\\ \\|\\ ↑\\ \\|\\↑\\ \\|↑\\ \\}$$ hear both 4s & 3d are more stable wait, are you sure you areDeepak Singh ? Yeah see the energy order of subshells Bcoz it\'s more stable for them to have half-filled D-subshells ? |
