This is how fluorine appears in the periodic table. Which is one piece of information that "9” gives about an atom of fluorine? The atomic mass is different than the atomic number, and the number of neutrons is the difference between the atomic mass and the atomic number. the atomic number the atomic mass the mass of protons the number of neutrons

Suppose a diode consists of a cylindrical cathode with a radius of 6.200×10^−2 cm , mounted coaxially within a cylindrical anode with a radius of 0.5580 cm . the potential difference between the anode and cathode is 260 v . an electron leaves the surface of the cathode with zero initial speed (v initial=0). find its speed vfinal when it strikes the anode.
