1.	Which of the following is isoelectronic?1. \( CO _{2}, NO _{2} \)2. \( NO _{2}^{-}, CO _{2} \)3. \( CN ^{-}, CO \)4. \( SO _{2}, CO _{2} \)
Answer» ions or atoms that have same number of electrons are called isoelectronic species. Here, CN^- and CO have same number of electrons — CN^-⇒ 6+7+1 = 14 e's CO ⇒ 6+8 = 14 e's Therefore, option (3) is right answer.

Which of the following is isoelectronic?1. \( CO _{2}, NO _{2} \)2. \( NO _{2}^{-}, CO _{2} \)3. \( CN ^{-}, CO \)4. \( SO _{2}, CO _{2} \)

Answer»

ions or atoms that have same number of electrons are called isoelectronic species.

Here,

CN^- and CO have same number of electrons —

CN^-⇒ 6+7+1 = 14 e's

CO ⇒ 6+8 = 14 e's

Therefore, option (3) is right answer.
