The correct answer is option D.
Explanation:
Cobalt and Nickel both are transition metals which means that their last electron enter d-orbitals.
These two elements have similar atomic masses but differ in the atomic number.
Atomic number is equal to the number of protons or electrons present in that element.
Atomic number = number of protons = number of electrons
Atomic Mass is the sum of protons and neutrons in an element
Atomic mass = Number of protons + Number of neutrons
For Cobalt:Atomic Number = 27
Number of protons = 27
Atomic mass = 59
Number of neutrons = 59 - 27 = 32
Hence, Number of protons in this element is 27 and number of neutrons are 32.
For Nickel:Atomic Number = 28
Number of protons = 28
Atomic mass = 59
Number of neutrons = 59 - 28 = 31
Hence, Number of protons in this element is 28 and number of neutrons are 31.
From the above information, it is visible that cobalt has one less proton that the nickel.Hence, the correct answer is option D.
