Q: What are electrons in the outer energy level of an atom called?


Read this paragraph and choose the correct option from the provided answers:

The electrons in the outer energy level of an atom are called valence electrons . It is valence electrons that are potentially involved in chemical reactions. The number of valence electrons determines an element’s reactivity, or how likely the element is to react with other elements. The number of valence electrons also determines whether the element can conduct electric current. That’s because electric current is the flow of electrons. Table below shows how these properties vary in elements from each class.

 Choices:

- shell electrons

- outer electrons

- positive electrons

- valence electrons


A:
valence electrons
