Which of the following sets of atoms can be joined by a ionic bond? a. C and H
b. Mg and Na
c. N and H
d. Na and Cl
e. P and Cl
It's not B

Na and Cl option d.

Explanation:

Ionic bond commonly occurs between a metal and non metal on combining to produce a compound.

In that case, the most appropriate choice would be to go with

option d - Na and Cl.

They combine to form common salt or NaCl.

Na ( sodium) is a metal while Cl (chlorine) is a non metal.

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.

the right answer is c i just did the question.
