Bonding and VSEPR Theory Flashcard

Front

What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds with other atoms.

Front

What does VSEPR stand for?

Back

VSEPR stands for Valence Shell Electron Pair Repulsion, a theory used to predict the geometry of molecules based on the repulsion between electron pairs.

Front

How many valence electrons does Beryllium have?

Back

Beryllium has 2 valence electrons.

Front

What is ionic bonding?

Back

Ionic bonding is a type of chemical bond that involves the transfer of electrons from one atom to another, resulting in the formation of charged ions.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons and the attraction between oppositely charged ions, while covalent bonds involve the sharing of electrons between atoms.

Front

What is the electron configuration of Beryllium?

Back

The electron configuration of Beryllium is 1s² 2s².

Front

What type of bond is formed between two fluorine atoms (F2)?

Back

The bond in F2 is a covalent bond, formed by the sharing of electrons.

Front

What is the significance of the octet rule in bonding?

Back

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

Front

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

Back

The shape of a molecule with four bonding pairs and no lone pairs is tetrahedral.

Front

What is the role of electron pairs in determining molecular shape?

Back

Electron pairs repel each other, and their arrangement around a central atom determines the molecular shape according to VSEPR theory.
