(a)
Interpretation:
The charge of an ion formed from the alkali metals needs to be determined.
Concept introduction:
In order to complete its octet elements can gain or lose electrons to attain noble gas configuration and become stable. The loss of electron results in the formation of positive charge cation and gaining of electron results in the formation of negative charge anion.
(a)
Answer to Problem 96A
The charge on the alkali metal is +1.
Explanation of Solution
The alkali metals are group I metals that contains elements
Thus, the loss of one electron results in the formation of positive charge cation having charge +1 and thus attaining the noble gas configuration.
(b)
Interpretation:
The charge of an ion formed from the alkaline earth metals needs to be determined.
Concept introduction:
In order to complete its octet elements can gain or lose electrons to attain noble gas configuration and become stable. The loss of electron results in the formation of positive charge cation and gaining of electron results in the formation of negative charge anion.
(b)
Answer to Problem 96A
The charge on the alkaline earth metal is +2.
Explanation of Solution
The alkaline earth metals are group II metals that contains elements
Thus, the loss of two electrons results in the formation of positive charge cation having charge +2 and thus attaining the noble gas configuration.
(c)
Interpretation:
The charge of an ion formed from the halogens needs to be determined.
Concept introduction:
In order to complete its octet elements can gain or lose electrons to attain noble gas configuration and become stable. The loss of electron results in the formation of positive charge cation and gaining of electron results in the formation of negative charge anion.
(c)
Answer to Problem 96A
The charge on the halogen is -1.
Explanation of Solution
The halogens are group VIIA metals that contains elements
Thus, the gain of one electron results in the formation of negative charge anion having charge -1 and thus attaining the noble gas configuration.
