Covalent Bonding

Front

What is a covalent bond?

Back

A covalent bond is a chemical bond formed when two atoms share one or more pairs of electrons.

Front

How many electrons are shared in a single bond?

Back

2

Front

What is the octet rule?

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 a double bond?

Back

A double bond is a type of covalent bond where two pairs of electrons are shared between two atoms.

Front

What is a triple bond?

Back

A triple bond is a type of covalent bond where three pairs of electrons are shared between two atoms.

Front

What does a Lewis structure represent?

Back

A Lewis structure represents the arrangement of atoms and the distribution of valence electrons in a molecule.

Front

What is the significance of bond length?

Back

Bond length is the distance between the nuclei of two bonded atoms; it is influenced by the number of shared electron pairs.

Front

What is the difference between polar and nonpolar covalent bonds?

Back

Polar covalent bonds occur when electrons are shared unequally between atoms, while nonpolar covalent bonds occur when electrons are shared equally.

Front

What is a molecule?

Back

A molecule is a group of two or more atoms bonded together by covalent bonds.

Front

How do you determine the number of valence electrons in an element?

Back

The number of valence electrons can be determined by the group number of the element in the periodic table.
