<u>Answer:</u>
<u>For a:</u> The charge on the ion formed is +3
<u>For b:</u> The charge on the ion formed is -2
<u>For c:</u> The charge on the ion formed is +2
<u>Explanation:</u>
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:
Aluminium is the 13th element of the periodic table having electronic configuration of
This element will loose 3 electrons to form ion
The charge on the ion formed is +3
Sulfur is the 16th element of the periodic table having electronic configuration of
This element will gain 2 electrons to form ion
The charge on the ion formed is -2
Strontium is the 38th element of the periodic table having electronic configuration of
This element will loose 2 electrons to form ion
The charge on the ion formed is +2
