(a)
Interpretation:
Symbol for monoatomic ion that is expected for potassium has to be written.
Concept Introduction:
In general, metals forms cations and nonmetals forms anions. The formation of cations and anions are to attain the stable octet electronic configuration. Charge of the cation that is formed by the metal atoms will be equal to the group number. Charge of the anions formed by the nonmetals will be equal to the difference between the group number and eight.
(b)
Interpretation:
Symbol for monoatomic ion that is expected for bromine has to be written.
Concept Introduction:
Refer part (a).
(c)
Interpretation:
Symbol for monoatomic ion that is expected for barium has to be written.
Concept Introduction:
Refer part (a).
(d)
Interpretation:
Symbol for monoatomic ion that is expected for sulfur has to be written.
Concept Introduction:
Refer part (a).
