Topic: JEE PYQ
Answer: 6. Full step-by-step solution below.
Correct answer: 6
Solution
(6) has complete octet in its dianionic form, thus in its atomic state it has 6 electrons in its valence shell. As it has negative charge, it has acquired two electrons to complete its octetMore Periodic Table & Periodicity PYQs
