The modern view of an electron orbital in an atom can best be described as Question 3 options:

A)

a circular path an electron follows around the nucleus.

B)

an elliptical path an electron follows around the nucleus.

C)

a three-dimensional space that shows the probability where an electron is most likely to be found.

D)

a spherical shell on the surface of which an electron can be found.

Explanation:

The modern view of an electron orbital in an atom can best be described as a circular path an electron follows around the nucleus.

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.
