The Periodic Table Part 1

Begin

This interactive uses PhET's Build and Atom Simulation.

Atoms are the building blocks of all matter.

Click on the building block.

Your response is not correct. Click anywhere to try again.

A wrong answer provides a great opportunity to learn something new!

You've got grit!Keep working hard!

Review the page. The answer is often on the page somewhere.

Different kinds of atoms are called elements.

Click on any of the different building blocks.

Like you might organize Legos, scientists have organized elements.

Click anywhere.

Elements are organized in a chart called the Periodic Table of Elements. Click on the chart to add the symbols for the 118 elements.

Periodic Table of Elements

Great! Now click on the chart to add the atomic number for each of the 118 elements.

Periodic Table of Elements

Fantastic! We now have a periodic table that shows the symbol and atomic number of each of the elements.The atomic number is very important because it is equal to the number of protons in that kind of atom. Click on the element that contains only 1 proton in each of its atoms.

Periodic Table of Elements

Yes! Hydrogen (H) is atomic number 1. This means that every hydrogen atom contains only 1 positively charged proton in its nucleus!Click on the proton in the model of the hydrogen atom.

1 proton

How many protons does every carbon (C) atom contain in its nucleus?

Periodic Table of Elements

Yes! Carbon's atomic number is 6. Therefore, we know every carbon atom has 6 protons in its nucleus.

Click on the box for the element that has 79 protons in its nucleus.

Periodic Table of Elements

Yes! Gold (Au) has an atomic number of 79. Therefore, we know every gold atom has 79 protons in its nucleus.Now, let's look at the rows of the periodic table. Each row is called a period.

Click on the periodic table to add the period labels.

Periodic Table of Elements

Period 4

As you go from left to right across a period (like you'd read a book), the atomic number increases by one for each element.

Click on the element whose atoms have 3 more protons than Carbon (C - atomic # 6) atoms.

Periodic Table of Elements

You got it! Carbon atoms have 6 protons and fluorine atoms have 9 protons.Now, take notice of the columns within the periodic table. Each column is called a group (or family).

Click on the periodic table to add the group labels.

Periodic Table of Elements

Group 4

Fantastic! Now that the periods (rows) and groups (columns) are labeled, click on the element that is in period 3 and group 13.

That's right! Aluminum (Al) is in period 3 and group 13.

Click on the element that is in period 4 and group 5.

Periodic Table of Elements

Great job finding Vanadium (V)!

Way to go! You found Vanadium. This is the end of the Periodic Table Part 1 interactive.

The next interactive will focus on the different groups within the periodic table.
