As you move down any group on the Periodic Table, atomic radius increases (due to extra energy levels of electrons, which expand the atom's volume.) Electrons that are farther away from the nucleus are easier to remove, due to gradually weaker Coulombic forces moving down the group. So, ionization energy decreases with each increment downward. This explains, for example, why cesium (Cs) is more reactive than sodium (Na).
Electronegativity decrease down in a group.
it increases
1. In a period is a trend of decrease from left to right but it is not absolute.2. In a group the atomic radius increase moving down.
Down a group, the number of shells increases, also the atomic size. Thus , the metallic character increase does increase as going DOWN a group. It is easy to remove an electron froman atom of bigger size.
The general trend with Ionization energy as you move down a column on the periodic table is that IE decreases. Ionization energy is the amount of energy required to remove an electron from an atom. As you move down a column, the electron moves farther away from the nucleus and the electron shielding effect increases. There is less of a pull keeping the electron in thus making it easier to remove.

The electronegativity increase in a period from left to right; in a group decrease by descending.
The bonds between the electrons
The boiling point decrease from lithium to caesium.
1. The ionization energy decrease down in the group.2. The cause is that the distance between the nucleus and the electron shell increase and the needed energy to extract an electron decrease.
because down the group the cation becomes gets larger so the hydration energy decreases. so the solubility decreases

Alkali metals get softer down Group 1 due to an increase in atomic size and weaker metallic bonding. As you move down the group, the atomic radius increases, leading to a decrease in the strength of metallic bonding and making the metals softer.
