X element uchun quyidagi birikmalardan qaysi biri mavjud bo'lmaydi?

  1. XPO₄
  2. X₂Cl
  3. XSO₄
  4. X₃O₄

📝 Detailed explanation

Xloridning formulasi X₂Cl bo'lishi uchun X ning valentligi ½ bo'lishi kerak, bu esa mumkin emas.
XPO₄ da X — 3 valentli, XSO₄ da X — 2 valentli, X₃O₄ da X — 8/3 valentli (Fe₃O₄ kabi).
X₂Cl formulasi kimyoviy jihatdan noto'g'ri, chunki Cl 1 valentli bo'lganda birikmada X ham 1 valentli bo'lishi kerak va formula XCl ko'rinishida bo'ladi.
