Chemical Bonding

Front

What are valence electrons?

Back

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

Front

How many valence electrons do Noble Gases have?

Back

Noble Gases have 8 valence electrons, making them stable and unreactive.

Front

What is the atomic number of Silicon (Si)?

Back

The atomic number of Silicon (Si) is 14, indicating it has 14 electrons.

Front

What is a chemical bond?

Back

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

Front

What are the two main types of chemical bonds?

Back

The two main types of chemical bonds are ionic bonds and covalent bonds.

Front

What happens in an ionic bond?

Back

In an ionic bond, one atom transfers electrons to another atom, resulting in the formation of charged ions.

Front

What happens in a covalent bond?

Back

In a covalent bond, two atoms share one or more pairs of electrons.

Front

Which bond is generally stronger: ionic or covalent?

Back

Ionic bonds are generally stronger than covalent bonds due to the electrostatic attraction between oppositely charged ions.

Front

What is a metallic bond?

Back

A metallic bond is a type of bond that occurs between metal atoms, where electrons are shared in a 'sea of electrons'.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight electrons.
