Covalent Bonding Flashcard

Front

What are valence electrons?

Back

Valence electrons are the electrons that orbit farthest from the nucleus of an atom and are involved in forming bonds with other atoms.

Front

How do we represent covalent bonds in diagrams?

Back

Covalent bonds are represented by circles in diagrams, indicating that electrons are shared between atoms.

Front

Between which types of elements does covalent bonding occur?

Back

Covalent bonding occurs between nonmetals and nonmetals.

Front

What is the Octet Rule?

Back

The Octet Rule is the desire for an element to have 8 electrons around it, which is often achieved through covalent bonding.

Front

Where are nonmetals located on the periodic table (excluding Hydrogen)?

Back

Nonmetals are found in the top right corner of the periodic table.

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

What is electronegativity?

Back

Electronegativity is the tendency of an atom to attract electrons towards itself when forming a chemical bond.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons.

Front

What is a molecule?

Back

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

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of covalent bond where electrons are shared unequally between two atoms, resulting in a slight charge difference.
