Today I will explain what a valence electron is and how many valence electrons each of the atoms your asking about have. :)
→ A valence electron is an electron in the outer shell of an atom that is able to participate in bonding. While iodine has 53 electrons, all but seven are in the inner shells of the iodine atom.
→ Sulfur has sixteen electrons in total, two in the inner shell, eight in the middle, and six in the outer. This means that sulfur has six valence electrons.

Answer:
Molecular Formula => (CH₂)₇ => C₇H₁₄
Explanation:
Empirical ratio is calculated from the sequence...
%/100wt => grams/100wt => moles => mole ratio => reduce mole ratio => Empirical Ratio
C: 85.7% => 85.7g => (85.7/12)mol = 7.14 mole
H: 14.3% => 14.3g => (14.3/1)mol = 14.3 mole
C:H mole ratio => 7.14:14.3
Reduced mole ratio (divide by the smaller mole value) => (7.14/7.14):(14.3/7.14) => Empirical Ratio => 1:2 => Empirical Formula => CH₂
Molecular Wt = Whole No. Multiple of Empirical Formula Wt.
M.Wt = N(Emp Wt) => 98g = N(14g) => N = 7
∴Molecular Formula => (CH₂)₇ => C₇H₁₄
A glacier is a large persistent body of ice. A geyser is a spring characterized by intermittent discharge of water ejected turbulently and accompanied by water vapor phase (steam). They both depend on water
<span>The solute is the substance that is being dissolved while the solvent is the base that the solute is bring dissolved in. For example, in salt water, salt would be the solute that dissolves into the water, and the water is the solvent that the salt is being dissolved in.</span>
