Question

Apresentando a configuração eletrônica 1s2 2s2 2p6 3s2 3p4 um determinado elemento químico se mostra com forte tendência para:

Answer 1

Answer:

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
