c) Anupam is quite intelligent and active
The metalloids are on the right side of the periodic table B, Si, Ge, As, Sb, Te, and At. The nonmetals are also on the right side next to the metalloids, there should be a He at the top right of the periodic table and there should be one more nonmetal at the top left of the periodic table that is H. And from the metals they are all on the middle next to the metalloids, starting from Li, Be, Na, and Mg as so on all of those are metals.

Answer:
45, 34, 36
Explanation:
The atomic number of Selenium is 34 and the atomic number is 79 also the atom has gained two electron denoted by superscript -2
number of neutrons = mass number - atomic number = 79 - 34 = 45
number of proton = atomic number = 34
number of electron = 34 + 2 = 36. In an atom the number of proton is always equal to number of electron if the atom is neutral but this Se atom has gain two so the number of electron will exceed the number of proton by 2.
