A worksheet to test your knowledge of valence electrons, the outermost electrons in an atom. Fill in the blanks with the number of valence electrons for each element and answer the questions about valence electrons and their properties.
Valence Electron Worksheet. Name ____________________ Period _____ 1. How many Protons are in the following elements? A. Carbon. B. Hydrogen . C. Oxygen. D. Phosphorus . E. Calcium. 2. Draw the Atomic Structures. Label the number of Protons, Neutrons and draw the Electrons in their orbits. A. Silicon. B. Potassium. C. Sulfur.
Students will be able to write the electron configuration for various elements and determine the number of valence electrons.
Lesson 2-3 Valence Electrons The Simple Atomic Model is used to represent the layout of EVERY electron in their “energy shells.” These energy shells are the most likely areas to find the electrons (electrons are weird and move all over). The electrons are represented by dots or small circles.

List the number of valence electrons for the following atoms: potassium = —L magnesium =
1: Identify whether each compound(s) is/are ionic. NaI; Au 2 CO 3; N 2 O; SiO 2; Answer. Only answers (a) and (b) are ionic compounds. Both formulas begin with a metal (atom from the left side of the periodic table) ion.
A worksheet for Chem 111 students to practice electron configurations and valence electrons of elements in different groups. It shows the number of electrons, the electronic configuration, and the valence configuration for each element in a table format.
A worksheet to practice finding the number of valence electrons for each element and explaining the octet rule. It also includes questions about the elementary components of an atom and their charge and location.
Chemistry: Valence Electrons & Lewis Dot Structures Worksheet. Apply your knowledge of valence electrons, Lewis dot structures and the octet rule to complete the table below.
