MCQ
Predict the formula of a compound formed between a metal 'M' which has 1st, 2nd, 3rd IP values as 518, 7314, 9820KJmol−1 respectively and a halogen 'X'.
- AMX2
- BM2X3
- CMX3
- DMX
✓
Answer
- MX
Explanation:
Alkali metals have low first ionization energies and relatively higher second and third ionization energies because the electron have to be remover from a stable octet.
As in the given question, there is more difference in the values of first and second ionization energies i.e. the metal has 1 valence electron,
∴ formula of the compound will be MX.
