A valence electron is an outer shell electron and may participate in the formation of a chemical bond. 1.The outermost electrons in each atom are called valence electrons.How many valence electrons does each fluorine atom have? Since it is one electron away from achieving an electron configuration of neon, a noble gas, would you expect fluorine to have high electronegativity or not? 4.Write the complete orbital diagram and electron configuration for bromine. Choose the appropriate number of atoms to make the bond. Step-by-step answers are written by … Thus it gains one electron and makes its valency to be -1. 7: it is a halogen. How many valence electrons does it have? That means it can hold more than eight valence electrons. And so we've used 2, 4, 6, 8, 10, 12, 14. Step-1: First, find the atomic number of potassium from periodic table. Identify the element in period 5, group 17. So sodium’s 11 electrons are arranged this way: 2 electrons in the first shell 8 electrons in the second shell; and 1 electron (the valence … Posted December 6, 2020. Problem 13 Give an example of an alloy. Search for "Gelson Luz" in your favorite browser to learn more. Fluorine is halogen and is the most electronegative element among the halogens.
