(c) sp³

(d) No valence orbital remains unhybridized.

Explanation:

Consider the SCl₂ molecule.

(a) What is the electron configuration of an isolated S atom?

S has 16 electrons. Its electron configuration is 1s² 2s² 2p⁶ 3s² 3p⁴.

(b) What is the electron configuration of an isolated Cl atom?

Cl has 17 electrons. Its electron configuration is 1s² 2s² 2p⁶ 3s² 3p⁵.

(c) What hybrid orbitals should be constructed on the S atom to make the S-Cl bonds in SCl₂?

SCl₂ has a tetrahedral electronic geometry. Therefore, the orbital 3s hybridizes with the 3 orbitals 3 p to form 4 hybrid orbital sp³.

(d) What valence orbitals, if any, remain unhybridized on the S atom in SCl₂?

No valence orbital remains unhybridized.

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6

put the answers   and i could answer.
