# Periodic Table of Elements Worksheets

• ###### Strange Trends

These worksheets are designed to help you understand the Periodic Table  better, remember the elements, and practice using the information the table provides to determine trends. They’re your training ground, helping you become an expert navigator of this table. With practice, you’ll be able to quickly locate and understand any element, its properties, and its relationships with others.

### What is the Periodic Table of Elements?

Imagine you have a huge box of LEGO blocks. To make it easier to build cool stuff, you’d want to organize these blocks by color, size, or shape, right? The Periodic Table does something similar but for elements, which are the basic building blocks of everything around us. Every element is made up of tiny particles called atoms, and each atom is unique.

The Periodic Table organizes all these different elements (currently over 100 of them!) in a way that makes it easy for scientists and students, like you, to understand their properties and how they relate to one another. Elements are arranged in rows and columns, and their position on the table tells us a lot about their characteristics.

### Types of Problems on Periodic Table Worksheets

Element Identification – These problems might ask you to identify an element based on its symbol or name. For instance, you might be given the symbol “O” and asked to write its name, which is “Oxygen”. Or, you might see a question like, “Which element has the symbol ‘Au’?” The answer is “Gold”.

Element Properties – Once you know an element’s name and symbol, you’ll want to learn about its properties. Questions might ask, “Is Chlorine a metal or non-metal?” or “What state of matter is Helium at room temperature?” By answering, you’ll get familiar with how elements behave and their different traits.

Element Location – The Periodic Table is organized in a very specific way. Some problems might ask you to find where an element is located. For example, “Which period (row) is Lithium in?” or “In which group (column) will you find Neon?” Knowing the position helps in understanding the element’s behavior.

Atomic Number and Atomic Mass – Each element on the Periodic Table has an atomic number (how many protons it has) and an atomic mass (roughly, the total weight of its protons and neutrons). Problems might ask, “What’s the atomic number of Carbon?” or “What’s the atomic mass of Iron?” These numbers give clues about the element’s structure and relationships with others.

Electron Configuration – This might sound a bit complicated, but it’s all about understanding how many electrons are around an atom and where they are. Questions could include – “How many electron shells does Sodium have?” or “How many electrons are in the outermost shell of Oxygen?” Knowing this helps in understanding why some elements react with others.

Element Families or Groups – Elements in the same column or group usually have similar properties. Questions might ask, “Which elements are Noble Gases?” or “Name an element in the Alkaline Earth Metals group.” Recognizing these families helps in predicting how an element might behave.

Comparing Elements – Sometimes, you’ll be asked to compare two or more elements. For example, “Which is heavier, a molecule of Oxygen or Nitrogen?” or “Which element is more reactive, Potassium or Lithium?” Comparing helps you see the relationships between different elements.
