is the symbol of the species with 23 protons and 21 electrons.
Hence, option F is correct.
<h3>What is a proton?</h3>Electrons are a type of subatomic particle with a negative charge. Protons are a type of subatomic particle with a positive charge.
If it has 23 protons, then its proton number (also know as its atomic number) is 23. You can look that symbol up in your periodic table.
If it has 21 electrons then it has a net charge of 23(+) - 21. So we know the ionisation state of the species, and we can record that as a superscript after the symbol for the species.
Hence, is the symbol of the species with 23 protons and 21 electrons.
