Chemical Bonding

Front

What is a chemical bond?

Back

A chemical bond is a lasting attraction between atoms, ions, or molecules that enables the formation of chemical compounds.

Front

What are the two main types of chemical bonds?

Back

Ionic bonds and covalent bonds.

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond formed through the electrostatic attraction between oppositely charged ions.

Front

What is a covalent bond?

Back

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

Front

What is the role of valence electrons in bonding?

Back

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

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.

Front

What is a molecule?

Back

A molecule is a group of two or more atoms bonded together, representing the smallest fundamental unit of a chemical compound.

Front

What is the difference between a compound and a mixture?

Back

A compound is a substance formed when two or more elements chemically bond, while a mixture is a combination of two or more substances that retain their individual properties.

Front

What is electronegativity?

Back

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

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 a molecule with a slight electrical dipole moment.
