How many neutrons does element x have if its atomic number is 24 and its mass number is 75?

The answer is: the element have 51 neutrons.

The atomic mass number of an element is equal to the sum of the number of protons and neutrons, also we need to remember that the atomic number is equal to the proton number.

So, to calculate how many neutrons does the element have, we need to write the following equation:

Where:

Hence,

So, the element have 51 neutrons.

Have a nice day!

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.

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.
