Question

An element \(\\_{12} M^{24} \) forms ionic compound with another element 'Y. Then the charge on the ion formed by M is 

• A. +1
• B. +3
• C. +2
• D. -2

Answer 1

The Correct Option is C

The atomic number of \( M \) is 12, which corresponds to magnesium (\( Mg \)) in the periodic table. Magnesium belongs to Group IIA (alkaline earth metals), and elements in this group typically lose 2 electrons to achieve a stable noble gas configuration.

Magnesium (\( Mg \)) loses 2 electrons to form a \( Mg^{2+} \) ion. Therefore, the charge on the ion formed by \( M \) is \( +2 \).

Final Answer: The charge on the ion formed by \( M \) is \( \mathbf{+2} \), which corresponds to option \( \mathbf{(3)} \).
