Transition metal and is a d-block element. :) ~Scandium~
That is the element phosphorous
there is no shorthand configuration for helium. its electron configuration is 1s2
The long form electron configuration for carbon is simply 1s2 2s2 2p2. The noble gas shortcut electron configuration for C is [He] 2s2 2p2.
Sulfur is the group 16, period 3 chemical element. Thus, its electron configuration is 1s2 2s2 2p6 3s2 3p4. Another way to write this is [Ne] 3s2 3p4 since the initial portion of the configuration is the same as neon's.
1s2 Or, He(2) i.e., Helium has only two electrons and it is a completely filled first shell making it the simplest noble gas.
Lithium (Li) has the electron configuration 1s2 2s1.
The electron configuration of beryllium is 1s2 2s2.
That is the element phosphorous
there is no shorthand configuration for helium. its electron configuration is 1s2
The electron configuration is the number of electrons in each energy level of an element. The electron configuration of Li is, 1s2 2s1. The electron configuration of F is, 1s2 2s2 2p5.
Fluorine's electron configuration is 1s2 2s2 2p5, and since fluoride is just fluorine with an extra electron, or F-1, its electron configuration is 1s2 2s2 2p6.
The long form electron configuration for carbon is simply 1s2 2s2 2p2. The noble gas shortcut electron configuration for C is [He] 2s2 2p2.
Potassium is the group 1, period 4 element on the periodic table. That means that its electron configuration is 1s2 2s2 2p6 3s2 3p6 4s1. This can be shortened to [Ar] 4s1 because argon's electron configuration is 1s2 2s2 2p6 3s2 3p6.
1s2 2s1
1s2 2s2 2p6 3s2 3p6 is the electron configuration of chlorine
Helium has the electron configuration 1s2
Neutral calcium's electron configuration is 1s2 2s2 2p6 3s2 3p6 4s2. Ca2+ is the ion of calcium, which means that it has 2 less electrons than neutral calcium. Therefore, its electron configuration is 1s2 2s2 2p6 3s2 3p6.
