The number "11" in the beginning of the chemical formula indicates that the atomic number of the element is 11, which means it has 11 protons. The given symbol is not a known element, but based on the given answer choices, the possible atomic mass is either 18 or 22. Option A is not valid because the sum of protons and neutrons is 18, and it cannot be an atomic mass for an element with 11 protons. Option C is also incorrect because the sum of protons and neutrons is 22, and it cannot be an atomic mass for an element with 11 protons. Option D is not possible because the sum of protons and electrons is 58, which is way higher than the atomic number, 11. Option E is also not possible because the sum of protons and electrons is 58, which is way higher than the atomic number, 11. Therefore, option B is the only valid answer. It indicates that the element has 11 protons (^{), 18 neutrons (}), and 18 electrons (^-) in its nucleus.
