Answer: Be= 2, C =4, Li = 1 and B=3
Explanation:
The valence shell can be define as the outermost shell of an atom that contains the valence electrons.
Beryllium (Be), electronic configuration; 1s2 2s2, = 2 electrons in its valence shell.
Carbon (C), electronic configuration; 1s2 2s2 2p2, = 4 electrons in its valence shell.
Lithium (Li), electronic configuration; 1s2 2s1 = 1 electron in its valence shell.
Boron (B) , electronic configuration; 1s2 2s2 2p1 = 3 electron in its valence shell.
Answer:
Explanation:
Bisulphate ion is a weak acid as it can form hydronium ion in water .
HSO₄⁻ + H₂O ⇄ SO₄⁻² + H₃O⁺
The equilibrium constant of this reaction is very small , hence bisulphate ion is very weak acid.
