Iodine has a lower atomic weight than tellurium (126.90 for i, 127.60 for te) even though it has a higher atomic number (53 for i, 52 for te). explain.

Explanation:

Iodine has lower atomic weight than tellurium, because tellurium has the atomic weight 127.60 and tellurium has the atomic weight 126.90 which comes after the element tellurium and lighter atomic weight than the tellurium. In the Mendleeve's table iodine is come before tellurium because iodine has less atomic weight than tellurium.

Iodine has higher atomic number than tellurium, because the atomic number 53 with iodine is higher than tellurium with atomic number 52. The atomic number is defined as number of protons present in the nucleus, which determines the chemical properties of the elements.

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
