What is the result when sodium and chlorine combine?

What is the electron configuration of a sodium ion (Na+) after it loses an electron?

How many protons are in a chlorine atom?

What type of ions do not bear any charge in ionic compounds?

What happens to the number of electrons in a chlorine atom when it gains one electron?

What occurs in the first step of forming sodium chloride?

Noble Gases and Stability

Noble gases, except helium, possess 8 electrons in their outermost shell, achieving a stable electronic configuration.
This stable octet means noble gases do not lose or gain electrons, existing in monoatomic form.

Electron Behavior in Metals and Non-metals

Metals and non-metals lacking a complete octet strive for stability by either gaining or losing electrons.

Formation of Sodium Chloride (NaCl)

Sodium (Na) has one electron in its outermost shell and loses it to achieve stability akin to noble gases.
Upon losing an electron, sodium becomes a positively charged ion (Na+) with 10 electrons and 11 protons.
The electron loss equation is: Na → Na+ + e-.

Chlorine Ion Formation

Chlorine (Cl) has seven electrons in its outermost shell and requires one additional electron to complete its octet.
Gaining an electron transforms chlorine into a negatively charged ion (Cl-) with 18 electrons and 17 protons.
The electron gain equation is: Cl + e- → Cl-.

Ionic Bonding in NaCl

The oppositely charged ions, Na+ and Cl-, attract each other through strong electrostatic forces, forming sodium chloride (NaCl).
This bond is classified as an ionic bond.
The ionic bond formation can be illustrated as: Na+ + Cl- → NaCl.

Characteristics of Ionic Compounds

Ionic compounds exist as aggregates of oppositely charged ions rather than individual molecules.
They are charge-neutral despite consisting of charged ions.

This quiz explores the concept of sodium chloride formation and the stability of noble gases' electron configurations. It highlights the tendency of metals and non-metals to achieve octet stability through electron exchange. Test your understanding of these fundamental chemistry concepts.
