Main Group Chemistry, (tutorial Chemistry Texts) (Android SIMPLE)

Highly reactive, +1 oxidation state. They are so soft they can be cut with a knife and react violently with water to form hydroxides and hydrogen gas.

Elements like Lithium and Magnesium share similar properties because their charge-to-size ratios are almost identical. MAIN GROUP CHEMISTRY, (Tutorial Chemistry Texts)

This is where chemistry gets diverse, moving from metals to metalloids to non-metals. Highly reactive, +1 oxidation state

Decreases across a period (increasing nuclear charge pulls electrons closer) and increases down a group. MAIN GROUP CHEMISTRY, (Tutorial Chemistry Texts)

The ability to attract electrons. Fluorine is the king here. 2. The s-Block (Groups 1 & 2)

To understand these elements, you have to look at the "Big Three" trends:

"Salt-formers." Highly electronegative and exist as diatomic molecules ( F2cap F sub 2 Cl2cap C l sub 2
