Question

For a  Nb atom,the number of protons,neutrons,and electrons in the atom is

Quizplus · Accepted Answer

The atomic number of Nb (Niobium) is 41, which signifies the number of protons in its nucleus. The given atom has a mass number of 93, which signifies the total number of protons and neutrons in its nucleus. Therefore, the number of neutrons in the nucleus is 93 - 41 = 52. Finally, since atoms are electrically neutral, the number of electrons is equal to the number of protons, which is 41. Thus, the correct answer is C, which gives the number of protons, neutrons, and electrons as 41, 52, and 41, respectively.
