Ionic and Covalent Bonding Concepts

The video tutorial introduces basic chemistry concepts, focusing on electron transfer and bond formation. It explains how atoms like sodium and chlorine form ionic bonds through electron transfer to achieve octet configuration. The tutorial also covers covalent bonds, using chlorine and hydrogen fluoride as examples, where atoms share electrons to complete their valence shells. The video concludes with exercises for students to apply their understanding and offers consultation for any questions.

What happens to sodium when it transfers its electron to chlorine?

• It forms a covalent bond.

• It remains neutral.

• It becomes a positive ion.

• It becomes a negative ion.

What is the main goal of sodium and chlorine in forming an ionic bond?

• To become neutral atoms

• To achieve a stable electron configuration

• To form a metallic bond

• To achieve a duet configuration

In the formation of sodium oxide, how many sodium atoms are involved?

• Three

• Two

• One

• Four

What type of bond is formed when chlorine atoms share electrons?

• Metallic bond

• Hydrogen bond

• Ionic bond

• Covalent bond

How many valence electrons does chlorine have before forming a covalent bond?

• Five

• Six

• Eight

• Seven

What is the result of electron sharing between two chlorine atoms?

• Formation of an ionic bond

• Formation of a covalent bond

• No bond formation

• Formation of a metallic bond

In hydrogen fluoride, what is the term for the shared electrons?

• Lone pair

• Bonding pair
