(a)
Interpretation:
The number of electrons that will be lost or gained by the given element as it changes into simple ions is to be predicted. The equation using elemental symbols, ionic symbols, and electrons to represent each change is to be stated.
Concept introduction:
Every element wants to attain an electronic configuration same as noble gas configuration, to do so elements either gain electrons or lose electrons. When an atomof element gains electrons, it forms an anion. When an atom of element loses electrons, it forms a cation.
(b)
Interpretation:
The minimum number of electrons that would have to be added and the minimum number that would have to be removed to change the electronic configuration of the given element to get a noble gas configuration are to be indicated.
