Chem Standards Blog Post

My Standard is to for students to know:

1. where to locate alkali metals
2. where to locate alkali earth metals
3. where to locate transitional metals
4. trends in ionization energy
5. trends in electronegativity
6. the relative sizes of atoms

The periodic table is split into columns (family) and rows (groups).
Almost each column has a specific name albeit the transitional metals.

• Group 1: Alkali Metals
• Group 2: Alkali Earth Metals
• Group 3-12: Transitional Metals
• Group 13-16: No Specific Name
• Group 17: Halogens
• Group 18: Noble Gases

Ionization Energy is the energy required to remove the outermost electron
Electronegativity is electron-greediness

Both increase as as atoms become smaller (going up and towards the right)

Atoms increase in size as the periodic table moves right.
As it reaches the end of a row, it moves onto the next row, and the mass of each atom increases.

Here are two Videos:

1. How to identify Groups of the Periodic Table
2. What is Ionization Energy, Electronegativity and Atomic Radius
