Covalent Flashcard

Front

What is a covalent bond?

Back

A covalent bond is a type of chemical bond where two non-metal atoms share one or more pairs of electrons to achieve a full outer shell and satisfy the octet rule.

What does it mean for an element to be diatomic?

Back

A diatomic element is one that naturally exists as two atoms bonded together, such as Cl2 (chlorine gas).

Front

How many electrons are shared in a single covalent bond?

Back

In a single covalent bond, one pair of electrons (2 electrons) is shared between two atoms.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to bond in such a way that they each have eight electrons in their valence shell, achieving a stable electron configuration.

Front

What type of bond is formed between two non-metals?

Back

A covalent bond is formed between two non-metals.

Front

How many covalent bonds are present in an ammonia (NH3) molecule?

Back

There are three covalent bonds in an ammonia molecule.

Front

What is the Lewis dot structure?

Back

The 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 is a single bond?

Back

A single bond is a covalent bond where one pair of electrons is shared between two atoms.

Front

What is a double bond?

Back

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

Front

What is a triple bond?

Back

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