1. The Periodic Table of Elements

3. Ti 22 4+ 3+ Titanium 47.9 atomic number ion charges(s) symbol 3+ Ti
Titanium
47.9
ion charges(s)
symbol
Each element has
its own box in the
periodic table!
name
atomic mass

4. Atomic Number The number of protons in the nucleus!
The atomic number increases one by one through the periodic table.

5. Atomic Mass This is the mass of an average atom of an element
It is always written as a decimal number
It is measured in atomic mass units (amu)

6. Ion Charge This is the electric charge that an atom has
It can be positive or negative, depending on how many electrons it has.
An element with a 2+ is missing two electrons
An element with a 2- has an extra two electrons.
Some elements have one charge, some have more a multiple ion charge

9. Periods
The HORIZONTAL rows are the periods.
They are numbered 1-7

10. Families or Groups Elements are arranged VERTICALLY in families
Families have similar physical and chemical properties

12. Groups 1-Alkali Metals 2-Alkaline Earth Metals 17-Halogens
18-Noble Gases

13. Metals, Non-Metals, and Metalloids
What characteristics do these have?
Metal Nonmetal Metalloid

15. Lets make a periodic table!
You will be given 2-3 cue cards with a chemical symbol on them.
Fill in all missing information
Blue cards are metals, yellow are metalloids, and pink are non-metals!
Create a large periodic table on the whiteboard!

16. Ti 22 4+ MP: 1668 °C BP: 3287°C 3+ Titanium 47.9 atomic number 3+ Ti

17. Periodic Game
Write your answers on the back of your cue card. Include the person’s name and what element they had in their possession

18. Find someone who has an element that starts with the same letter

19. Find someone who has a mass that is only 4-5 g different than yours

20. Find someone who has an element that is double your atomic number (or you may have to find someone who is half yours)

21. Find someone who has an element that is the same charge as yours.

22. Find someone who has an element that has a different charge than you

23. Find someone who has an element with an atomic mass less than yours

24. Find someone who has an element with an atomic mass greater than yours

25. Find someone who has an element that becomes before you in the alphabet.

26. Find someone who requires a higher melting point than you.

27. Find someone who has a boiling point that is at least 1000 degrees away from your boiling point

28. Find someone who has a melting point that is less than yours.
