Unit 03: Chemical Bonding I & II

Front

What are Noble Gases?

Back

Noble gases are a group of chemical elements that are odorless, colorless, monatomic gases with very low chemical reactivity. They include Helium, Neon, Argon, Krypton, Xenon, and Radon.

Front

True or False: Noble Gases always want to form compounds.

Back

False

Front

What type of bond is formed in CH4 (methane)?

Back

Covalent bond.

Front

What are the characteristics of Ionic Bonds?

Back

Ionic bonds form salts, have high melting points, are hard/brittle, and dissociate into ions when dissolved in water.

Front

What is the definition of a Covalent Bond?

Back

A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms.

Front

What is the definition of an Ionic Bond?

Back

An ionic bond is a type of chemical bond that occurs between two atoms when one atom donates an electron to another, resulting in the formation of ions.

How many valence electrons does Gallium have?

Back

3

How many valence electrons does Phosphorus have?

Back

5

Front

What is the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons in order to have eight electrons in their valence shell, achieving a stable electron configuration.

Front

What is a metallic bond?

Back

A metallic bond is a type of chemical bond that occurs between metal atoms, characterized by a 'sea of electrons' that are free to move around, allowing for conductivity and malleability.
