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 carbon have?

Back

Carbon has 4 valence electrons.

Front

What is the octet rule?

Back

The octet rule states that atoms are most stable when they have eight electrons in their valence shell.

Front

How many valence electrons does oxygen have?

Back

Oxygen has 6 valence electrons.

Front

What is the significance of valence electrons in chemical bonding?

Back

Valence electrons determine how an atom can bond with other atoms, influencing the formation of molecules.

How many valence electrons does sodium have?

Back

Sodium has 1 valence electron.

Front

What is the maximum number of valence electrons an atom can have?

Back

The maximum number of valence electrons an atom can have is 8, according to the octet rule.

Front

How do you determine the number of valence electrons in an element?

Back

The number of valence electrons can be determined by the group number of the element in the periodic table.

Front

What is the relationship between valence electrons and an element's reactivity?

Back

Elements with fewer valence electrons tend to be more reactive as they seek to lose or gain electrons to achieve a stable configuration.
