Keeping in mind different factors which affect the melting point of a substance,the compound having highest melting point among the following is
Correct answer: A. NaCI
- A. NaCI
- B. RbCI
- C. LiCI
- D. CsCI
Explanation
The melting point of an ionic compound is influenced by factors such as the strength of the ionic bonds and the size of the ions. Generally, as the size of the ions increases, the melting point decreases.In the given options:NaCl (Sodium chloride) has the highest melting point among the alkali metal halides listed.RbCl (Rubidium chloride) and LiCl (Lithium chloride) have lower melting points than NaCl.CsCl (Cesium chloride) has the lowest melting point among the alkali metal halides listed.So, the correct answer is (a) NaCl.

About Atomic Structure
Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
