How many valence electrons does Sc have?
Understand the Problem
The question is asking about the number of valence electrons for the element Sc (scandium). Valence electrons are the outermost electrons in an atom and are important for understanding an element's chemical behavior.
Answer
3 valence electrons
The final answer is 3 valence electrons.
Answer for screen readers
The final answer is 3 valence electrons.
More Information
Scandium has three valence electrons, one in the 3d orbital and two in the 4s orbital.
Tips
A common mistake is to confuse the 3d orbital electrons as non-valence electrons, but in transition metals, these can count as valence electrons.
