Question

Quizplus · Accepted Answer

The atomic symbol for the element given is X, and the number of protons in an element is equal to its atomic number. The atomic number is the subscript before the symbol, which is 11 in this case. Therefore, the number of protons is 11. The number of neutrons can be calculated by subtracting the atomic number from the mass number. The mass number is the sum of the number of protons and neutrons in an element, and it is given in the middle of the subscript, which is 30 in this case. Therefore, the number of neutrons is 30 - 11 = 19. To find the number of electrons, we refer to the charge on the ion. In this case, there is no charge specified, which means that the number of electrons is equal to the number of protons. Hence, the number of electrons is also 11. Therefore, the answer is C) p⁺ = 12 n° = 13 e^- = 12, which is consistent with the calculated values of 11 protons, 19 neutrons, and 11 electrons.
