To determine:
The number of electrons and electron shells in fluorine along with the number of electrons needed to fill the valence shell.
Introduction:
Fluorine is an element with an atomic number 9. It belongs to halogen family of P-block and group 17 in the periodic table. It is an highly toxic gas which is pale yellow in color It is the most electronegative element and is extremely reactive. Compounds of fluorine are used industries for the manufacturing of products.
For example: sodium fluoride is used in making toothpaste and is also used in drinking water to prevent dental cavities. Hydrofluoric acid is used in making glass bulbs.

- Why do the 3s, 3p, and 3d orbitals have the same energy in a hydrogen atom but different energies in a many- electron atom?arrow_forwardLook up the valence electron configuration, covalent atomic radius, effective nuclear charge, first ionization energy and Pauling electronegativity in Chapter 8 (tables are attached). Examine the above data and answer the following questions. a) Explain why some of the elements like TI and Pb on the lower left of the p block are metallic. b) Explain why some of the elements like C, Si in the center of the p block form covalent bonds. Explain why these bonds formed by the network of these elements (as studied in Chapter 25) tend to be unreactive. c) Explain why the noble Group 8A elements are highly unreactive gases. d) Explain why some elements like F, CI, Br etc, on the upper right of the p block are highly reactive nonmetals.arrow_forwardUnshared, or lone, electron pairs play an important role in determining the chemical and physical properties of organic compounds. Thus, it is important to know which atoms carry unshared pairs. Use the structural formulas below to determine the number of unshared pairs at each designated atom. Be sure your answers are consistent with the formal charges on the formulas. H₂C H₂ b Hc N CH2 The number of unshared pairs at atom a is The number of unshared pairs at atom b is The number of unshared pairs at atom c is The number of unshared pairs at atom a is 1 v The number of unshared pairs at atom b is Ov The number of unshared pairs at atom c is 1.arrow_forward
