Apresentando a configuração eletrônica 1s2 2s2 2p6 3s2 3p4 um determinado elemento químico se mostra com forte tendência para: a) perder 5 elétrons.
b) compartilhar 4 elétrons.
c)ganhar 1 elétron
d)perder 1 elétron.
e)
ganhar 2 elétrons

E

Explanation:

To know what will happen, we need to know

the total number of electrons the element have.

This can be calculated by adding all the electrons together

That would be 2 + 2 + 6 + 2 + 4 = 16

This shows that the element is sulphur.

Now using the KLMN electronic configuration, sulphur has the shells 2,8,6 meaning there are 2 extra electrons needed for octet configuration to be achieved.

This makes option E the correct answer to the question

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.
