Ionic and Covalent Bonds

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond formed through the transfer of electrons from one atom to another, resulting in the formation of charged ions.

Front

What is a covalent bond?

Back

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

Front

What are valence electrons?

Back

Valence electrons are the electrons located in the outermost energy level of an atom, which are involved in forming 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.

Front

What is the Lewis dot structure?

Back

The Lewis dot structure is a diagram that shows the bonding between atoms of a molecule and the lone pairs of electrons that may exist.

Front

How many valence electrons does Oxygen have?

Back

Oxygen has 6 valence electrons.

Front

What is the molecular structure of carbon dioxide (CO2)?

Back

The molecular structure of carbon dioxide is linear, with one carbon atom double bonded to two oxygen atoms.

Front

What is the difference between ionic and covalent bonds?

Back

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

Front

What is electronegativity?

Back

Electronegativity is a measure of an atom's ability to attract and hold onto electrons in a chemical bond.

Front

What type of bond is formed between sodium (Na) and chlorine (Cl)?

Back

An ionic bond is formed between sodium (Na) and chlorine (Cl) due to the transfer of an electron from sodium to chlorine.
