The symbol for the species that contains 22 protons, 26 neutrons, and 18 electrons is:

Question

Quizplus · Accepted Answer

The symbol for an element includes the element's atomic number (number of protons) and atomic mass (number of protons plus neutrons). In this case, the element has 22 protons and 26 neutrons, so its atomic mass is 22 + 26 = 48. The element's symbol is found by looking up the element with atomic number 22 on the periodic table, which is titanium (Ti). Finally, the charge of the species is equal to the number of protons minus the number of electrons, which is 22 - 18 = +4. Therefore, the symbol for the species is "Ti⁴⁸⁺". Choice D is the only option that includes titanium and the correct atomic mass and charge.
