Answer:
d. selenium (Se) I’m a non metal
Explanation:
What we know about the element in view is that it has:
4 orbitals
6 valence electrons
The orbitals are the energy levels in the element.
Valence electrons are the outermost shell electrons.
The orbitals tells us the periods in which an element belongs. Since we have 4 orbitals, this suggests that our element belongs to the 4th period.
The number of valence electrons tells us the group in which the element could be found. Since we have 6 valence electrons, the group number is 6.
Therefore, the element is period 4 and group 6 is selenium. Selenium is a non-metal.
