Dear student,
- Comparing this situation to elements we get that : First orbit can accommodate 2 electrons , second orbit can accommodate 8 electrons and third orbit can accommodate 4 electrons.
- So the element has 14 electrons in total. and hence atomic number is also 14
- The element is Silicon which is a metalloid and has electronic configuration as 2,8,4. Hence the valency is +4 or -4 (depending on compound)
- The students respects their teacher. They are co-operative. They know how to wrk in a group.
