Question

Graphite and iodine are nonmetals but they shine,why?

Answer 1

Iodine is metalloid and hence posses the property of both non metals as well as metal so that's why by having shining luster it behaves like a metal

Answer 2

Answer:

Iodine Shines because of the shielding effect due to interaction between the atoms.

Graphite shines because of its structure.

Explanation:

Graphite shines because of its orderly lattice structure reflecting light. Graphite is also conductive to electricity. Iodine on the other hand shines because of the increased size of the atom being near the bottom of its group in the periodic table. Most elements are metals and nonmetals occupy one right hand corner of the periodic table. Any nonmetal group (IV-VII) exhibits more metallic characteristics as you go further down the group. Examples; carbon to lead,nitrogen to Antimony, oxygen to polonium etc. Group VII is no different. Fluorine a light extremely reactive nonmetal has all the way to iodide a nonmetal brittle solid with metallic luster.
