Alien Periodic Table
Column 1 – Ch should be at the top, and Q in period 4.
The inert/Noble gases – Bo in period 1, L in period 2, J in period 3, and Wo in period 4.
Halogens – Column 17, with V in period 4.
Metalloids – Column 13: E in period 2, Yz in period 3
Column 14: Hi in period 3, T in period 4
Column 15: SS in period 4

Ask Mr. Z
3. Why are elements that gain of lose only one electron considered the most reactive?
a. They are “desperate” to achieve a full electron shell and will readily react to gain.lose as
necessary.
4. Metals – ductile, malleable, conductive, and shiny. Non-metals: nonductile, non malleable, non
conductive, and non-shiny (aka dull).
5. Mendeleev first organized by increasing atomic mass.
