Elements each have unique properties and characteristics. They cannot be broken down further by chemical means. Each element has a certain number of neutrons, protons, and electrons.Answer and Explanation: One atom of fluorine has 10 neutrons. The element fluorine, which is a gas, can be ...
The number of protons determines the element, but the number of neutrons in the atom of any one element can vary. Each variation is an isotope. Only one radioactive isotopes of fluorine, fluorine-18, has been prepared. A radioactive isotope is one that breaks apart and gives off some ...
What is the valency of fluorine and how to find it? What is the difference between an isotope and an element? What element has 53 protons and 74 neutrons? What is the atomic number for bromine? What is the Bohr model for fluorine?

The mass number of fluorine is 19 and its atomic number is 9. Calculate the number of protons , electrons and neutrons in the fluorine atom. How will the flu
The energyes of these peaks assuming them to be comprising of protons, deutrons or tritons are given and they agree with those to be expected from known levels of the final nuclei. In general the emission at forward angles is found to be much more than at backward angles is (5.5卤0.5)...

In this scenario, the N from preceding CNO burning is converted to F, via the reaction N(α,)F and subsequent β-decay forms O, which then produces neutrons via O(α,n) or O(α,γ)Ne(α,n). The statistical model predicted that the F(α,p)Ne reaction can compete with the β-...
