Neither K2+ nor K2+ exist but even a putative configuration is impossible without knowing what one you mean.
pottasium has this electron configuration 1s22s22p63s23p64s1 also known as [Ar]4s1
chloride has this electron configuration 1s22s22p63s23p5 also known as [Ne]3s23p5
2, 8, 8, 1 for the element K
2, 8, 8 for the ion, K+
or
1s2 2s2 2p6 3s2 3p6 4s1 for the element K
1s2 2s2 2p6 3s2 3p6 for the cation, K+
The Fe2 plus electron configuration is 1s2 2s2 2p6 3s2 3p6 3d6.
Potassium chloride + water
There is merely one unpaired electron in Potassium. The electron configuration of potassium is [Ar]4s^1. This means that potassium has all the electrons of argon, plus one more in the 4s orbital. All the electrons of argon are paired, so the one electron in the 4s orbital is the only unpaired electron.
The chloride ion has an electron in plus.
You will get a solution of potassium chloride and potassium hypochlorite.
Potassium + Chlorine --> Potassium Chloride (potassium plus chlorine arrow potassium chloride)
The Fe2 plus electron configuration is 1s2 2s2 2p6 3s2 3p6 3d6.
The electron configuration of Cu2+ is [Ar]3d94s0.
Cobalt electron configuration is [Ar]3d7.4s2.Cobalt(2+) electron configuration is [Ar]3d7.
Potassium chloride and Iodine
Potassium chloride + water
Cobalt(II) electron configuration is [Ar]3d7.
Potassium is an Alkali Metal meaning that its configuration is that of a noble gas [Ar] plus s1 [Ar] 4s1 OR 1s2 2s2 2p6 3s2 3p6 4s1
There is merely one unpaired electron in Potassium. The electron configuration of potassium is [Ar]4s^1. This means that potassium has all the electrons of argon, plus one more in the 4s orbital. All the electrons of argon are paired, so the one electron in the 4s orbital is the only unpaired electron.
The electron configuration for a magnesium cation Mg2 plus is 1s2.2s2.2p6.
The chloride ion has an electron in plus.
probably yes
