Answer:
The frequency is 
Explanation:
From the question we are told that
The energy required to ionize boron is 
Generally the ionization energy of boron pre atom is mathematically represented as
Here 
is the Avogadro's constant with value 
So
=> 
Generally the energy required to liberate one electron from an atom is equivalent to the ionization energy per atom and this mathematically represented as
=> 
Here h is the Planks constant with value 
So
=>
Answer:
A cation is formed when a metal ion loses a valence electron while an anion is formed when a non-metal gains a valence electron. They both achieve a more stable electronic configuration through this exchange.

Answer:
The rapid movement of excess charge from one place to another is an <em>electric discharge.</em>
Explanation:
A material in which electrons <em>CANNOT</em> move easily from place to place is an insulator. A material in which electrons <em>CAN </em>move easily from place to place is a conductor.
