Bonding and VSEPR Theory Flashcard

Front

What type of bond is formed between lithium and fluorine?

Back

Ionic bond: A bond formed when one atom transfers electrons to another, resulting in the attraction between oppositely charged ions.

Front

What is an ionic compound?

Back

An ionic compound is formed when a metal reacts with a nonmetal, resulting in the transfer of electrons and the formation of ions.

Front

Magnesium Bromide is classified as what type of compound?

Back

Ionic compound: A compound consisting of ions held together by electrostatic forces.

Front

How many valence electrons does magnesium have?

Back

2 valence electrons: Magnesium is in group 2 of the periodic table, indicating it has 2 valence electrons.

Front

What elements typically form covalent bonds?

Back

Two or more nonmetals: Covalent bonds occur when nonmetals share electrons.

Front

What is the VSEPR theory?

Back

Valence Shell Electron Pair Repulsion (VSEPR) theory predicts the shape of molecules based on the repulsion between electron pairs.

Front

What is the shape of a molecule with four bonding pairs and no lone pairs?

Back

Tetrahedral: A molecular shape where four pairs of electrons are arranged around a central atom.

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 partial charges.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons.

Front

What is a lone pair of electrons?

Back

A lone pair is a pair of valence electrons that are not shared with another atom.
