Answer:
For a: The charge on the ion formed is +3
For b: The charge on the ion formed is -2
For c: The charge on the ion formed is +2
Explanation:
An ion is formed when an atom looses or gains electron.
- When an atom looses electrons, it will form a positive ion known as cation.
- When an atom gains electrons, it will form a negative ion known as anion.
For the given options:
- Option a: Al
Aluminium is the 13th element of the periodic table having electronic configuration of [tex]1s^22s^22p^63s^23p^1[/tex]
This element will loose 3 electrons to form [tex]Al^{3+}[/tex] ion
The charge on the ion formed is +3
- Option b: S
Sulfur is the 16th element of the periodic table having electronic configuration of [tex]1s^22s^22p^63s^23p^4[/tex]
This element will gain 2 electrons to form [tex]S^{2-}[/tex] ion
The charge on the ion formed is -2
- Option c: Sr
Strontium is the 38th element of the periodic table having electronic configuration of [tex]1s^22s^22p^63s^23p^64s^23d^{10}4p^65s^2[/tex]
This element will loose 2 electrons to form [tex]Sr^{2+}[/tex] ion
The charge on the ion formed is +2
