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 does Silicon (Si) have?

Back

Silicon (Si) has 4 valence electrons.

Front

What is the electron configuration of Magnesium (Mg)?

Back

The electron configuration of Magnesium (Mg) is 1s² 2s² 2p⁶ 3s².

Front

What is the significance of the electron configuration 1s² 2s² 2p⁶?

Back

This configuration represents a full outer shell, indicating that the atom has 8 valence electrons, which is characteristic of noble gases.

Front

What are anions?

Back

Anions are negatively charged ions that are formed when nonmetals gain electrons.

Front

What is the electronic configuration of Iron (Fe)?

Back

The electronic configuration of Iron (Fe) is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d⁶.

Front

How do you determine the number of valence electrons from an electron configuration?

Back

To determine the number of valence electrons, look at the highest principal energy level (n) and count the electrons in that level.

Front

What is the maximum number of electrons that can occupy the outermost shell of an atom?

Back

The maximum number of electrons that can occupy the outermost shell is 8, following the octet rule.

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 8 electrons.

Front

What is the difference between cations and anions?

Back

Cations are positively charged ions formed when an atom loses electrons, while anions are negatively charged ions formed when an atom gains electrons.
