Bonding Practice

Front

What is a lone pair?

Back

A pair of non-bonding electrons.

Front

Why does Francium (Fr) have the lowest ionization energy in Group 1?

Back

Its 1 valence electron is very far from the nucleus, so little energy is needed to remove it.

Front

What happens to electrons when a bond is formed between a hydrogen atom and a sulfur atom?

Back

Electrons are shared to form a covalent bond.

Front

According to VSEPR theory, what do molecules adjust their shapes to keep as far away as possible?

Back

Pairs of valence electrons.

Front

What type of intermolecular force is present in HCl?

Back

Dipole-dipole.

Front

Define ionic bond.

Back

A chemical bond formed through the transfer of electrons from one atom to another.

Front

What is a covalent bond?

Back

A chemical bond formed by the sharing of electrons between atoms.

Front

What is the significance of valence electrons in bonding?

Back

Valence electrons are involved in forming bonds between atoms and determine the chemical properties of an element.

Front

What is the octet rule?

Back

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 electronegativity?

Back

A measure of the tendency of an atom to attract a bonding pair of electrons.
