What happens to chromium that makes it an exception to the order of filling orbitals?
Chromium is an exception to the electron configuration pattern because electrons will occupy subshells until half-full and THEN start pairing up. We would expect chromium to follow the trend after Vanadium:
V 'Ar' 3d3 4s2- All the subshells are either full or half full (or empty)
Cr 'Ar' 3d4 4s2- this is the configuration expected- but this is less STABLE for the atom.
The true configuration is:
Cr 'Ar' 3d5 4s2
This is so the d block is completely half full as is the s block meaning it is more stable. This links with the fact that electrons occupy subshells until half full and THEN start pairing up.

What happens if you don't get enough chromium picolinate?
A deficiency in chromium picolinate can lead to impaired glucose metabolism, reduced energy production, and an increased risk of insulin resistance. Symptoms may include fatigue, weight gain, and difficulty regulating blood sugar levels.
What do electrons do to the nucleus?
Electrons orbits around the nucleus, which have neutrons and protons. When there is an imbalance of protons and electrons, it creates a static electricity. What I am trying to say is, nothing really special happens.
What is the difference between always and all the time?
You always do something whereas something happens all the time.
Why is there no chemical equation to describe what happens when water evaporates?
That's because there is no chemical change. In most cases, there is no chemical change when a substance evaporates. The exception is very long molecules, which may break apart during evaporation.
What happens to the knot hole?
As the tree grows, the knot hole can become covered up by new growth or get pushed out over time. The wood around the knot hole may also continue to grow and expand, filling in the space where the knot hole used to be.
What happens once an atom has full s and p orbitals in its outermost energy level?
Depending on what the level is, it may start filling d orbitals, or start on a new shell with s orbitals available.
What happens when chromium reacts with potassium bromate?
Oxygen is transferred from bromate ion(s) to the Chromium ion. Leaving hypobromous ion, and/ or bromide ion.
What happens to chromium when heated at 20 degrees Celsius?
Nothing, a passivation occur.
What happens when chromium and calcium are put together?
They both go up in the air
What happens when you go on filling air in the balloon?
epic fail...
What happens when you get too much chromium in your diet?
You start to shine and need chrome cleaner once a month!
What happens when you mix chromium (III) nitrate and ammonia?
When chromium (III) nitrate is mixed with ammonia, a pale blue-green precipitate of chromium hydroxide is formed. This reaction is pH-dependent, with the specific color and composition of the precipitate varying based on the concentration of ammonia and the pH of the solution.
What happens to your teeth if you doesn't get a filling?
rot away and your gums bleed
When the user changes a value in a cell Excel automatically recalculates?
Yes, that is what normally happens. The only exception is when manual recalculation is turned on, which is very rare. In that case you have to press the F9 key to do a recalculation.Yes, that is what normally happens. The only exception is when manual recalculation is turned on, which is very rare.

How many electrons does the neutral atom gain or lose when Cr3 plus forms?
When Cr3+ forms, the neutral atom (chromium) loses 3 electrons. This happens because the neutral chromium atom has 24 electrons, but when it forms Cr3+, it loses 3 electrons to have a total of 21 electrons.
Sensitization of steel?
Sensitization happens when a stainless steel is held at an intermediate temperature (typically ~425 - 815 degrees Celsius) and chromium carbides precipitate at the grain boundaries. This precipitation of chromium carbides at the grain boundaries happens because the carbides are insoluble at these temperatures. In order for the carbide to precipitate, it must get chromium from the surrounding metal. This means that there is a chromium depleted zone around the grain boundaries. It should be apparent that this chromium depleted zone will be less corrosion resistant, specifically to intergranular corrosion. Sensitization is particularly important in metals that are welded. This is because the welding zone experiences temperatures in the range that can cause sensitization. This can cause localized intergranular corrosion at the weld site.
Do you have to fill out papers to get engaged?
No. It is just a commitment to get married. Filling out papers only happens for marriage.
