Answer 2

Answer:

the answer is c.

option a: incorrect as proton no is same as electron no and elements with 9 e are in group 9 meaning it is a non metal.

option b: incorrect

option d: incorrect as t and z have different number of protons meaning different number of electrons which overall means that they will be in different periods

this leaves option c: CORRECT. because r has less electrons then z meaning R is more reactive then Z.

So the answer is : OPTION C.
