What defines a chemical bond?

A chemical bond is the force of attraction between any two atoms in a molecule that maintains stability.

Noble gases have a stable electronic configuration because their outermost shell is ___.

True or False: Atoms of noble gases can lose, gain, or share electrons.

False. Noble gases do not lose, gain, or share electrons and are inert.

Fill in the blank: The driving force for chemical bonding is the tendency of atoms to attain the stable electronic configuration of the nearest ___.

Riddle: I am a type of bond formed by the complete transfer of electrons from one atom to another. What am I?

An electrovalent bond.

Short answer: Name the three methods for achieving chemical bonding.

True or False: The octet rule applies only to the element helium.

False. The octet rule applies to all noble gases except helium, which follows the duplet rule.

What is an ionic bond, and how is it formed?

Ionic bonds transfer electrons.

• Formed between metals and nonmetals.

• Electrons are transferred, not shared.

• Creates charged ions attracting each other.

Fill in the blank: The number of electrons donated or accepted by the valence shell of an atom to achieve stable electronic configuration is called ___ .

Riddle: I am formed when metals lose electrons and non-metals gain them, creating a bond that holds them together. What am I?

An ionic bond.

Explain the role of electron affinity in the formation of anions.

Higher values of electron affinity (EA) in non-metallic atoms facilitate the ease of gaining electrons, leading to the formation of anions.

Fill in the blank: Sodium chloride is an example of an ___ compound.

Ionic

What is covalency?

Covalency is the number of electron pairs that an atom shares with one or more atoms to achieve a stable electronic configuration.

List two examples of non-polar covalent compounds.

What type of covalent compound is characterized by shared electrons that are equally distributed?

Non-polar covalent compound.
