What are facts about fluorine?
Interesting facts about fluorine (F). Fluorine is the most receptive and most electronegative of all the chemical elements. The elements with which it doesn’t respond are oxygen, helium, neon, and argon. Fluorine is the only element which will shape compounds with noble gasses xenon , krypton , and radon.
What is the formula for the atomic number?
Atomic number: Number of protons present in the nucleus is called atomic number (Z) of an element. Atomic weight: The sum of mass number of proton and mass number of neutron is called atomic weight or atomic mass number (A). A = Z + n°. Example: 19K39. Z = 19 and A = 39 as per atomic weight definition.
