Question

List the properties of copper, sulfur, and copper sulfide.

Answer 1

Chemical Formula CuS

Molecular Weight 95.61

CAS No. 1317-40-4

Group Copper 11
Sulfur 16

Crystal Structure Hexagonal

Lattice Constant 3.961 Å

Answer 2

Copper (Cu)

Atomic Number: 29

Element Category: Transition metal

Electron Configuration:
`3d^(10) 4s^1`

Sulfur (S)

Atomic Number: 16

Element Category: Reactive nonmetal

Electron Configuration:
`3s^(2) 3p^4`

Copper Sulfide (Cu
`_(n)`S
`_(n)`)

Step-by-step explanation:

Copper sulfides will always vary in composition (0.5 ≤ Cu/S ≤ 2) because their bonds are somewhat covalent and have complicated electronic band structures because of their high degree of delocalization.
