Question

(a) Write the electron-dot structures for potassium and chlorine.
(b) Show the formation of $KCl$ by the transfer of electrons.
(c) Name the ions present in the compound, $KCl$ .
(Atomic number of $K = 19,\,\,Cl = 17$ )

Answer 1

Hint:‌ To solve this question, we must first understand the concept of electron dot structure. Then we need to assess the compounds that are used in the formation of wine and then only we can conclude the correct answer.

Complete step by step answer:
Before we move forward with the solution of this given question, let us first understand some basic concepts:
Electron Dot Structure: also called Lewis dot structures are diagrams that describe the chemical bonding between atoms in a molecule. They also display the total number of lone pairs present in each of the atoms that constitute the molecule. Lewis dot structures are commonly referred to as electron dot structures or Lewis structures. Lewis defined a base as an electron pair donor and an acid as an electron pair acceptor.
 In Lewis dot structures each dot represents an electron. A pair of dots between chemical symbols for atoms represents a bond. Lines are drawn between atoms that are bonded to one another (pairs of dots can be used instead of lines). Excess electrons that form lone pairs are represented as pairs of dots, and are placed next to the atoms.
a) Electron dot-structure for potassium and chlorine are as follows:

b) Formation of $KCl$ by the transfer of electrons:

c) ions present in the compound, $KCl$ are: ${K^ + }$ and $C{l^ - }$

Note: A simpler method has been proposed for constructing Lewis structures, eliminating the need for electron counting: the atoms are drawn showing the valence electrons; bonds are then formed by pairing up valence electrons of the atoms involved in the bond-making process, and anions and cations are formed by adding or removing electrons to/from the appropriate atoms.
