Valence Electrons

Front

What are valence electrons?

Back

Electrons in the outermost shell of an atom that are involved in chemical bonding.

Front

What group do elements with 2 valence electrons belong to?

Back

Group 2 of the periodic table.

Front

Which element is considered stable or inert?

Back

Argon (Ar) is considered stable and inert due to its full outer electron shell.

Front

What is the octet rule?

Back

Atoms tend to gain, lose, or share electrons to achieve a full outer shell of 8 electrons.

Front

Which group of elements is known as the noble gases?

Back

Group 18, which includes elements like Helium (He) and Neon (Ne), known for their stability.
