2 \({\rm{NaH}}\)
3 \({\rm{Ca}}{{\rm{F}}_{\rm{2}}}\)
4 \({\rm{B}}{{\rm{F}}_{\rm{3}}}\)

An atom with atomic number 20 is most likely to combine chemically with the atom whose atomic number is
1 11
2 16
3 18
4 10
Explanation:
An atom with atomic number 20 is most likely to combine chemically with the atom whose atomic number is 16, which is sulfur. This is because elements tend to combine in chemical reactions to achieve a stable electron configuration, often by gaining or losing electrons to attain the electron configuration of the nearest noble gas. In this case, an atom with atomic number 20 (calcium, Ca) is likely to combine with an atom with atomic number 16 (sulfur, S) to form an ionic compound such as CaS.

Ionic compounds do not exhibit space isomerism because
1 They are solids
2 The ionic bond is non-directional
3 They are electrolytes
4 They contain ions
Explanation:
To exhibit isomerism, bond must be directional

In which solvent NaCl has maximum solubility?
NaCl is an ionic compound and solubility of an ionic compound depends on the value of dielectric constant of the solvent. Higher the value of dielectric constant of the solvent more is the solubility of the ionic compound. Among the given solvents, water has highest dielectric constant
