Electron Configuration for Copper (Cu, Cu+, Cu2+)

Therefore, one of the 4s2 electrons jumps to the 3d9. This give us the (correct) configuration of: 1s2 2s2 2p6 3s2 3p6 3d10 4s1. For the Cu+ ion we remove one electron from 4s1 leaving us with: 1s 2 2s 2 2p 6 3s 2 3p 6 3d 10. For the Cu2+ ion we remove a total of two electrons (one from the 4s1 and one form the 3d10) leaving us with.

Organic Treatments for Fungal Infections

Copper fungicide is better at killing existing fungus and sulfur is good for preventing spread, so sulfur is better to apply at the first sign of fungal issues. We'd recommend cutting away as much infected material as you can and then applying a copper fungicide to kill what's left.

Innovations: Introduction to Copper: Mining & Extraction

The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.
