Why chromium and copper have different electron configuration? Since chromium had 4 electrons, which is one short of 5 electrons to get just hslf-filled. To attain a completely filled electronic configuration copper gains one electron from the d-orbital and attains the electronic configuration of (Ar) d10 4s1. Thus both Cr and Cu have exceptional electronic configuration.
Why configuration of Cr and Cu is irregular? Re: Why are Copper and Chromium exceptions? These two elements are exceptions because it is easier for them to remove a 4s electron and bring it to the 3d subshell, which will give them a half filled or completely filled subshell, creating more stability.
How do the electron configurations of chromium and copper contradict? How do the electron configurations of chromium and copper contradict the Aufbau principle? In chromium, each 3d orbital gets 1 electron before 4s gets two & in copper, each 3d orbital gets two electrons before 4s gets two.
Can you use any solder on copper? These days we normally use a tin and copper alloy, as lead isn’t safe. However, leaded solder is still on the market. Safety Tip: Never use lead solder on copper pipes that carry drinking water. If you can avoid using leaded solder completely, do so.

How to take care of a copper sink?
All copper sinks should be washed with warm water, mild dish soap, and a soft sponge. Dry your sink after cleaning or using it to prevent mineral deposits and green spotting. If you want to keep your polished sink shiny, apply a copper cleaner and wax at least every six weeks.
How copper protects your body?
Copper is an essential nutrient for the body. Together with iron, it enables the body to form red blood cells. It helps maintain healthy bones, blood vessels, nerves, and immune function, and it contributes to iron absorption. Sufficient copper in the diet may help prevent cardiovascular disease and osteoporosis, too.
What type of chemical reaction is copper and silver nitrate?
Silver nitrate (AgNO3) reacts with copper (Cu) to form copper(II) nitrate (Cu(NO3)2) and silver (Ag). This can be called a redox reaction because silver nitrate is reduced and copper is oxidized. This can also be called a single replacement reaction because copper replaces silver in the substance silver nitrate.
How to insulate around copper pipes?

Why is ground wire bare copper wire?
Bare copper is the most commonly used type of copper wire and is often referred to with the general term “grounding wire.” It does not have any sort of protective coating, however, the lack of insulation allows bare copper to have the best conductive properties.
How big is the copper scroll?
