The element that has chemical properties most similar to sulfur (S) is selenium (Se). Selenium is in the same group (Group 16) as sulfur in the periodic table and exhibits similar chemical properties, such as forming compounds with similar oxidation states and similar reactivity towards other elements.

The mass number of an atom is the sum of its protons and neutrons. Since the atomic number of fluorine (F) is 9 (indicating 9 protons in the nucleus), if the mass number is 19, the number of neutrons in the atom would be 19 - 9 = 10 neutrons.

Without the specific properties mentioned in the chart, it is not possible to determine which element is most likely a nonmetal. The classification of an element as a metal or nonmetal is based on its specific chemical and physical properties. Some general properties of nonmetals include being poor conductors of heat and electricity, having low melting and boiling points, and forming negative ions. Please provide more information from the chart for a more accurate answer.
