Gas with a mass number of 19
WebA glass tube is filled with hydrogen gas at low pressure. An electric current is passed through the gas, causing it to emit light. ... An atom has an atomic number of 9, a mass number of 19, and an electron configuration of 2–6–1. Explain why the number of electrons in the second and third shells show that this atom is in an excited WebWe know that the atomic number of fluorine is 9 and the atomic mass number is about 19. Neutron = 19 – 9 = 10. Therefore, a fluorine atom has ten neutrons. Based on the atomic number, mass number, and neutron number of the element, three things can be considered. These are isotope, isobar, and isotone.
