﻿ Periodic Table Worksheets
A series of worksheets that helps students understand how to use and apply the information presented by The Periodic Table of Elements.

#### Noted scientist Dmitri Mendeleev was touted as creating the first version of the Periodic Table. He showed that a certain arrangement of elements could lead us to understand the properties of other elements that were related to each other. He also used it to predict the properties of elements that were either not discovered yet or not normally found in nature. Elements on the table are ordered by their number of protons which is equivalent to their atomic number. The elements on the table can be found at room temperature in all of the various phases. Students can use the Periodic Table to help them predict the outcome of chemical reactions and the stability of compounds in the modern science classroom. Elements that exist in the same column of the table tend to not only similar chemical properties, but also form similarly charged ions. As you progress from right to left in a row of elements several trends emerge: the amount of energy required to remove an electron increases, the radius of an atom of the element decreases, as well as the increased tendency to attract a pair electrons. This really helps us also write the chemical formulas for compounds and balance chemical equations.

The worksheets range from finding basic information about particular elements that are found in nature to working on determine atomic operations such as neutron numbers. These worksheets start by thoroughly explaining the information that can be found on a single atom of an element on the table. We then look into all the compositional math that exists for these elements. We show you how to determine the number of protons, neutrons, and electrons found in a stable atom of each element. As we progress, we will present students with fun puzzles that helps sum up everything we can learn from this marvel of science.

## Understanding Table Data

Use the values shown in the boxes below to label the parts of the picture of the entry for Nitrogen.

## Atomic Numbers- Electrons, Neutrons, and Protons

Because neutrons and protons are almost the same mass, the total number of protons and neutrons in an atom is the atomic mass. Therefore, by subtracting the atomic number from the atomic mass you can calculate the number of neutrons.

## Using the Periodic Table of Elements Sheet 1

Use the chart and your knowledge of chemistry to complete the blanks for atoms of each element. You will learn the not only find the atomic number, mass, and symbol, but you will learn how to translate that to a a number of protons, neutrons, and electrons for a stable atom.

## Worksheet 2

Round Atomic Mass to the nearest whole number.

## The Periodic Puzzle

The location of an element into columns can give information about its chemical properties. Provide the letter of the element in the table above that best fits the description below.

## Periodic Crossword

They mostly describe Groups and Periods that elements are arranged in, but there will be the occasional extensive question for you too.
