Hello students. In the question they have asked about the selenium Selenium is an element which has atomic number is equals to 34. First question they’ve asked us, is that how many unpaid shared electrons does selenium elements have in the ground state at them? See first of all be right. The electronic configuration for lydia it will be equals to electronic qualification of selenium will be equals two. All the good three D 10 four S two for beautiful. This is the electronic configuration of selenium in the ground state. So still Argon argon atomic number of organization. So tell argon all the orbiters will be fed three D 10. If President De has five orbiters These shall have five orbiters And if 10 electrodes are present then all the electrons will be presented hail the phone four s 2 exception has one orbital and the two electoral represented in exceptional. Also the Electrons are present in the period form then we see the four before This option has three orbiters. If 40 accounts are present, first single electron will be distributed in each orbital, then the pairing occurs. So we clearly see that We have two orbiters with uncared electrons. So a number of unpaid electrons answer for the first question will be number oven paired electrons in the ground state of the selenium will be Equals to two. This is the answer of our first question. 2nd day have asked that Consider the Celine Dion Celine Dion will be SC -2. We have to tell out that what are the total number of electrons in its reception? See if a selenium has -2 negative charge. It means it has gained two electrons. That is why it carries two units negative charge. It has gained two electrons. So now it’s electronic configuration will become Arden three D 10.…
