An element E has the electronic configuration 1s²2s²2p⁴ .What is the formula of its compound with lithium? A) LiE₂ B) LiE C) Li₂E D) Li₄E

Question

Quizplus · Accepted Answer

The compound with lithium will form a salt by transferring one electron from lithium to element E. The resulting compound will have the formula LiE, with E having a negative charge. To indicate the charge of E, we use the prefixes S1U1B1 for -1, S1U1B2 for -2, and so on. Therefore, the formula of the compound with lithium is LiS1U1B1E. Option C is the only one that contains this formula. Options A and D contain the S1U1P1 subshell, which is not relevant here. Option B is too general and does not indicate the charge on element E.
