Chem Investigation 3: Bonding and VSEPR Theory Flashcard

Front

What type of bond is formed between lithium and fluorine?

Back

Ionic bond.

Front

What elements generally compose a covalent bond?

Back

2 or more nonmetals.

Front

What do valence electrons represent in an atom?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in bonding.

Front

What is an ionic compound?

Back

An ionic compound is formed when atoms transfer electrons, typically between a metal and a nonmetal.

Front

What is the Lewis dot structure used for?

Back

The Lewis dot structure is used to represent the valence electrons of an atom and how they bond with other atoms.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons between atoms.

Front

What is the VSEPR theory?

Back

VSEPR (Valence Shell Electron Pair Repulsion) theory is used to predict the geometry of individual molecules based on the repulsion between electron pairs.

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.

Front

What is the significance of the octet rule in bonding?

Back

The octet rule states that atoms tend to bond in such a way that they have eight electrons in their valence shell, achieving a stable electron configuration.

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of bond where electrons are shared unequally between two atoms, resulting in a molecule with a slight charge.
