Explanation:

10. Sulfur dichloride formula

Step1: Identify elements and prefixes

Sulfur is \(S\), "di -" means 2 for chlorine (\(Cl\)).

Step2: Write the formula

Based on prefixes, formula is \(SCl_{2}\).

11. Disulfur decafluoride formula

Step1: Identify elements and prefixes

"Di -" for sulfur (\(S\)) means 2, "deca -" for fluorine (\(F\)) means 10.

Step2: Write the formula

Formula is \(S_{2}F_{10}\).

12. Bond between \(H\) and \(S\)

Step1: Check electronegativity difference

Electronegativity of \(H = 2.1\), \(S=2.5\). Difference \(\Delta\chi=2.5 - 2.1=0.4\).

Step2: Classify the bond

Since \(0<\Delta\chi<1.7\), it is a polar covalent bond.

13. Bond between \(C\) and \(H\)

Step1: Check electronegativity difference

Electronegativity of \(C = 2.5\), \(H = 2.1\). Difference \(\Delta\chi=2.5 - 2.1 = 0.4\).

Step2: Classify the bond

Since \(0<\Delta\chi<1.7\), it is a non - polar covalent bond (very small difference, considered non - polar in some simplifications as the electron distribution is nearly even).

14. Most electronegative element

Step1: Recall periodic table trends

Electronegativity increases across a period and decreases down a group. Fluorine (\(F\)) is the most electronegative.

Answer:

1. \(SCl_{2}\)
2. \(S_{2}F_{10}\)
3. polar covalent bond
4. nonpolar covalent bond
5. Fluorine (\(F\))
