Fill in the periodic table below using electron-dot diagrams and atomic mass numbers only.
Hydrogen has been done for you as an example.
H.
1.00 | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | |Transition Metals (more complicated)
skip ‘em for now… | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | |
**Lightly shade the metals blue and the non-metals red on the table above (hint: stair step line)
Answer the following questions based on the periodic table above:
1. What happens to the size of the element as you move from left to right across the table?
2. What happens to the size of the elements as you move from the top to the bottom for each family/group?
3. What are valence electrons and why are they so important for understanding chemistry?
4. What pattern do you notice as you move across OR down the table when considering valence electrons?
5. Based on the electron-dot diagrams and what you know about an element’s ability to bond/react with other elements, which chemical family is the most reactive (most likely to bond with others) and why?
6. Which chemical family would be least reactive (least likely to bond with others) and why?
