Valence Electron Worksheet: 1. How Many Protons Are in The Following Elements?

This document is a worksheet about valence electrons that contains questions about the atomic structure of various elements. It asks students to identify the number of protons in certain elements, draw atomic structures labeling protons, neutrons, and electron orbits, and determine whether elements will gain or lose electrons to achieve stable outer electron shells. It also asks students to determine the charge of elements after gaining or losing electrons.
