CH. 3 Atoms and Bonding

Front

What are ionic bonds?

Back

Ionic bonds are formed between two ions that have opposite charges, resulting in an attraction between them.

Front

How many valence electrons does Lithium (Li) have?

Back

Lithium has 1 valence electron.

Front

How many valence electrons does Aluminum have?

Back

Aluminum has 3 valence electrons.

Front

Why do most elements create chemical bonds?

Back

Most elements create chemical bonds to reach eight valence electrons, which makes them stable.

Front

How many valence electrons are shared in a double bond?

Back

In a double bond, 4 valence electrons are shared.

Front

What is a valence electron?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds.

Front

What is the octet rule?

Back

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

Front

What is a covalent bond?

Back

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

Front

What is a Bohr Diagram?

Back

A Bohr Diagram is a simple representation of an atom that shows the nucleus and the arrangement of electrons in energy levels.

Front

What is the difference between ionic and covalent bonds?

Back

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