WebThe formula H + ·H 2 O is also commonly written as H 3 O + and denotes the hydronium or oxonium ion. The amount of hydrogen ion present in a water solution is used as a … WebJan 23, 2024 · In CH3, the C atom has 4 valence electrons because it has 4 electrons in its outermost shell. H each has a 1 valence electron. CH3 has 4 + 1*3=7 valence electrons. In the OH group, the O atom has 6 valence electrons. H again has 1 valence electron. OH has a total of 6+1 = 7 valence electrons. The total number of valence electrons in CH3OH is …

Web3. thus by the formula, the oxidation state of oxygen in many cases = expected # of electrons - actual # of electrons = 6 - 8 = -2 for the second question: 1. actually there's no way to figure out "usual" oxidation state of an atom including that of oxygen as far as i know WebAug 30, 2024 · The total number of electrons is thus 9 – 1 = 8. Since this is an octet of electrons, we can place them all around the O atom. The final structure then follows very easily: A central O shares three pairs of electrons with three H on the left top and right side. The bottom pair of electron from O is unpaired. rc control for wokwi
