Choose all the answers that apply. Fluorine (F) has an atomic number of 9 and an atomic weight of 18.99. Fluorine has .

at least one isotope
10 neutrons
18 electrons
9 protons
an atomic mass of 19

9 protons

Explanation:

By looking at the periodic table, you will see that Fluorine has 9 protons. Since the number of electrons equal the number of protons, Fluorine has 9 electrons as well. Meanwhile, it's mass number of 19, minus 10 neutrons, gives you 9 protons or electrons. Hence, the atom would be Fluorine.

hope u make me brainlesst ʘ‿ʘ

i think so for this i will 9 protons . atomic mass is 19. 10 neutrons

the product of the pressure and volume is also constant
