Study Notes
The s-Block Elements of the Periodic Table
- The s-block elements have their last electron in the outermost s-orbital, with two groups (1 & 2) belonging to this block.
- Group 1 elements are known as alkali metals and form strongly alkaline hydroxides when reacting with water.
- Group 2 elements, except beryllium, are alkaline earth metals and have alkaline oxides and hydroxides found in the earth's crust.
- Sodium and potassium are abundant in alkali metals, while calcium and magnesium rank fifth and sixth respectively in abundance in the earth's crust for alkaline earth metals.
- Francium is highly radioactive and radium is the rarest of all elements.
- The general electronic configuration for alkali metals is [noble gas]ns1 and for alkaline earth metals is [noble gas]ns2.
- Lithium and beryllium exhibit anomalous properties similar to magnesium and aluminum, respectively, due to diagonal relationship in the periodic table.
- Monovalent sodium and potassium ions and divalent magnesium and calcium ions are found in large proportions in biological fluids and perform important biological functions.
- Alkali metals show regular trends in their physical and chemical properties with increasing atomic number.
- All alkali metals have one valence electron, ns1, making them the most electropositive metals.
- The atomic and ionic radii of alkali metals increase while going from Li to Cs, and their ionization enthalpies decrease down the group.
- The hydration enthalpies of alkali metal ions decrease with increasing ionic sizes, with Li+ having the maximum degree of hydration and mostly found in hydrated salts.
