Which is a characteristic of a strong base

Explanation:

The strong bases have following properties:

1.In solution, strong bases ionize fully.

2.On dissolving the strong bases in water they produce all hydroxide ion which they have.  

3.For strong bases the value of equilibrium constant (Kb  ) is large.

4.In general the strong base ionizes completely means concentration of ions are greater means conductivity also greater.

5.For strong bases the value of equilibrium constant (Kb) is large, thus the value of dG0 is very large negative number.

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
