Sagot :
Based on the bond length, the molecular weight of the unknown metal X is 23.
What are ionic compounds?
Ionic compounds are compounds which are formed between oppositely charged ions.
When hydrogen combines with the group 1 metals, they form ionic compounds.
The group one metals that combine with hydrogen to firm ionic bonds include:
- Lithium to give Lithium hydride with equilibrium bond length of 0.239Å.
- Sodium to give sodium hydride with equilibrium bond length of 1.896Å.
- Potassium to give potassium hydride with equilibrium bond length of 2.321Å
The molecular weight of lithium is 7 g
The molecularweight of sodium is 23
The molecular weight of Potassium is 39.
Therefore, based on the equilibrium bond length, the molecular weight of the unknown metal X is 23.
