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

Define polar covalent bond.

Back

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

Front

What is a nonpolar covalent bond?

Back

A nonpolar covalent bond is a type of covalent bond where the electrons are shared equally between the two atoms, resulting in no electrical dipole moment.

Front

What is the significance of electronegativity in covalent bonding?

Back

Electronegativity is a measure of an atom's ability to attract shared electrons. It helps determine whether a bond will be polar or nonpolar.

Front

How do you determine if a molecule is polar or nonpolar?

Back

To determine if a molecule is polar or nonpolar, assess the symmetry of the molecule and the electronegativity differences between the atoms.

Front

What is a Lewis dot structure?

Back

A Lewis dot structure is a diagram that represents the valence electrons of atoms within a molecule, showing how they are shared or transferred.

Front

What does a double bond represent in a Lewis dot structure?

Back

A double bond represents two pairs of shared electrons between two atoms.

Front

What is the molecular formula for Selenium tetrafluoride?

Back

The molecular formula for Selenium tetrafluoride is SeF4.

Front

What is the molecular formula for tetraarsenic decoxide?

Back

The molecular formula for tetraarsenic decoxide is As4O10.

Front

What is the difference between ionic and covalent compounds?

Back

Ionic compounds are formed by the transfer of electrons from one atom to another, while covalent compounds are formed by the sharing of electrons.
