what are the properties of elements related to?\n○ an elements symbol\n○ the average atomic mass\n○ the number of electrons that fill the outer shell\n○ the total number of electrons
Answer
Answer:
the number of electrons that fill the outer shell
Brief Explanations:
The chemical properties of elements are mainly determined by the number of valence - electrons (electrons in the outer shell). They influence an element's reactivity and bonding behavior.
