Answer:
NaOH
Explanation:
Look at charge Na has +1 charge and Ca has +2 charge after dissociation . Greater charge Stronger lattice. And as we need weak Lattice, so NaoH is stronger base than Ca(OH)2.
Answer: The particles are moving fast but close together.
Answer:
going down the periodic table atomic size increases,electronegativity and ionization decreases going down
