Ionic Covalent Bonds

The video tutorial explains the concept of covalent and ionic bonds. It begins with an introduction to covalent bonds, followed by a detailed explanation of ionic bonds using sodium and chlorine as examples. The tutorial then introduces hydrogen and its simple atomic structure, leading to a discussion on how hydrogen atoms form covalent bonds by sharing electrons, resulting in a stable configuration.

What type of bond involves the sharing of electrons between atoms?

• Ionic bond

• Covalent bond

• Hydrogen bond

• Metallic bond

In an ionic bond, what happens to the sodium atom?

• It becomes positively charged

• It remains neutral

• It becomes negatively charged

• It shares electrons

What is an ion?

• A neutral atom

• An atom with a complete shell

• An atom that is charged

• An atom that shares electrons

Why can't hydrogen atoms form an ionic bond with each other?

• They are already stable

• They both need an electron

• They have too many electrons

• They are too far apart

What do hydrogen atoms do to achieve stability?

• Share electrons

• Give away electrons

• Take electrons from each other

• Remain unstable

How many electrons does each hydrogen atom feel it has after forming a covalent bond?

• Four

• Three

• Two

• One

What is the significance of having two electrons for hydrogen atoms?

• It makes them unstable

• It completes their first shell

• It makes them positively charged

• It allows them to form ionic bonds

What is the main difference between ionic and covalent bonds?

• Ionic bonds involve sharing electrons

• Covalent bonds involve metallic elements

• Covalent bonds involve giving and taking electrons

• Ionic bonds involve giving and taking electrons

Why are covalent bonds considered stable?

• Because they involve taking electrons

• Because they involve sharing electrons

• Because they involve metallic elements

• Because they involve giving electrons

What happens to the electrons in a covalent bond?

• They are gained

• They are lost

• They are shared

• They are transferred
