How many valence electrons in H2SO4
To determine the number of valence electrons in the H2SO4 molecule (sulfuric acid), we need to consider the number of valence electrons for each type of atom in the molecule:
1. Hydrogen (H): Each hydrogen atom has 1 valence electron. Since there are two hydrogen atoms, they contribute a total of 2 valence electrons.
2. Sulfur (S): Sulfur is in Group 16 (also known as VI or 6A) of the periodic table, so it has 6 valence electrons.
3. Oxygen (O): Each oxygen atom has 6 valence electrons because oxygen is also in Group 16. Since there are four oxygen atoms, they contribute a total of 24 valence electrons (6 electrons per oxygen atom × 4 oxygen atoms).
Now, sum up the valence electrons from all the atoms:
Hydrogen: 2 valence electrons (2 × 1)
Sulfur: 6 valence electrons
Oxygen: 24 valence electrons (4 × 6)
Total number of valence electrons = 2 (from H) + 6 (from S) + 24 (from O) = 32 valence electrons in the H2SO4 molecule.
