Structure 1 is satisfying octet rule because each atom surrounded by 8 electrons:
The valance electron for oxygen is 6, for sulfur is 6, but for hydrogen is 1. Therefore, the molecule has <span>valance electrons. Sulfur is bonded with 4 oxygen atoms, 4 single bonds, whereas 2 hydrogen atoms are bonded with 2 oxygen atoms.
But the actual structure is 2 but it violates octet rule since S is surrounded in this case with 12 electrons

Explanation:
An atom is made up of:
- Protons which are the positively charged particles
- Electrons are negatively charged
- Neutrons carry no charges.
Atomic number is the number of protons in an atom.
To find the nuclear charge:
We use the effective nuclear charge formula:
Effective nuclear charge = Atomic number - number of shielding electrons(non-valence electrons)
The shielding electrons are the non-valence electrons in the inner orbitals.
For example:
Ne:
atomic number = 10
Effective nuclear charge = 10 - (2) = 8+
Number of non-valence electrons is 2
The effective nuclear charge is 8+
Overall charge:
Charge = number of protons - number of electrons
For neutral atoms, the overall charge is zero as the number of protons and electrons are the same.

The question is incomplete, the complete question is;
Enter the chemical formula of a binary molecular compound of hydrogen and a Group 6A element that can reasonably be expected to be more acidic in aqueous solution than H2S , e.g. have a larger Ka.
Answer:
H2Se
Explanation:
The acidity and extent of acid dissociation (shown by Ka value) depends on the nature of the bond between hydrogen and the group 6A element.
If we compare the H-S bond and the H-Se bond, we will discover that the H-Se bond is longer, weaker and breaks more easily than the H-S bond. As a result of this, H2Se is more acidic than H2S.
