The lone pair of electrons in Theobromine are shown in RED color in attached figure.
Details:
In chemistry there are two types of electrons.
i) Bonding Pair Electrons:
These are those electrons which are being shared and are involved in making bonds. They are also called as sharing electrons. In given structure all the solid bonds either single or double are made up of bonding pair electrons.
ii) Lone Pair / Non-Bonding Pair Electrons:
Those electrons which doesn't take part in bonding and are not shared between atoms. In given structure the lone pair of electrons are found only on nitrogen atoms (single lone pair) and oxygen atoms (two lone pair of electrons) respectively.
Hybridization of Nitrogen Atoms;
N₁ = Sp²
N₂ = Sp³
N₃ = Sp³
N₄ = Sp³
Hybridization of Oxygen Atoms;
O₁ = Sp²
O₂ = Sp²
Answer:
The electron configuration for Iron (Fe) with 26 electrons is as follows 1s²2s²2p⁶3s²3p⁶4s²3d⁶ (the superscripts add up to 26) or the Noble gas [Ar] 4s²3d⁶
Explanation:
The subshells fill up in the order 1s, 2s,2p, 3s,3p,4s,3d... (etc) the subshells have the following number of e⁻ (electrons) s: 2, p:6, d:10, f:14. I attached the subshell levels and where to find them on the periodic table that I made when I taught this to myself after lecture. You can use the noble gas from the previous row to make this simpler to write.
