Answer : Ionic compound is created when potassium and chlorine combine. The chemical formula of the compound is KCl.
Explanation :
When potassium and chlorine combine then the type of compound created is Ionic compound.
Ionic compound : These are those compounds which are made of a metal element and non-metal element. Salts are ionic compound which consists of a positive and negative ions.
The electronic configuration of Potassium is,
The electronic configuration of Chlorine is,
From this we conclude that the potassium atom is a metal which has 1 electron in their valence shell and chlorine atom is a non-metal which has 7 electrons in their valence shell. For the complete octet, chlorine atom needs only 1 electron which it receives from the potassium atom.
During this process, potassium atom will loses 1 electron and acquire positive charge and chlorine atom will gain 1 electron from potassium atom and acquire negative charge.
The chemical formula of the compound is KCl.
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
