They are grouped together as they have similar chemical reactivities because they have the same number of valence electrons. Relevance. Group 2 (II) (alkaline earth metals) 2 . The other members belonging to the same family comprise chlorine, fluorine, and iodine. Log in Sign up. The alkaline earth metals all react with the halogens to form ionic halides, such as calcium chloride (CaCl Answer: d. Alkaline The noble gases in the right-most column (Ne, Ar, Kr, etc.) The halogens posses seven valence electrons; Explanation: Valence electrons are the electrons in the outermost orbitals of the atoms, which are the orbitals with the highest main energy level (principal quantum number). There are thus 7 valence electrons for Fluorine, 2 in the 2s orbital, and 5 in the 2p orbitals. 1. Ready To Place An Order? All halogens have 7 valence electrons.

With the exception of groups 3–12 (the transition metals and rare earths), the columns identify by how many valence electrons are associated with a neutral atom of the element. LOGIN TO VIEW ANSWER. The number of valence electrons of an element can be determined by the periodic table group, the vertical column in the Periodic Table of Elements. electronegativity: The tendency of an atom to attract electrons to itself. How many valence electrons do halogens have? This means that each of these elements have an electron configuration that ends as s^2p^5 F 1s^2 2s^2 2p^5 Cl 1s^2 2s^2 2p^6 3s^2 3p^5 Br 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^5 Each Halogen ends in s^2p^5 with 7 valence electrons. borrow one electron. - Definition & Equation, What is a Chemical Formula? How many valence electrons does an atom of any halogen have? What do you call the electrostatic forces that hold ions together in an "ionic" compound? The group number in which the element belongs to is equal to the total number of valence electrons of that element. Valence Electrons. How many valence electrons do the halogens possess? Halogens each have 7 valence electrons. How many valence electrons does lithium (Li)... How many valence electrons does boron (B) have? Express the following number in scientific notation. Matthew_Fayoyin. Halogens; 7 valence electrons; Reactive nonmetals; Melting points and boiling points increase with increasing atomic number; High electron affinities; Change state as it moves down the family, with fluorine and chlorine existing as gases at room temperature while bromine is a liquid and iodine is a solid; 10. of 10 . all have 8 electrons except for Ne, which only has 2 electrons. halogens: Group 17 (or VII) in the periodic table consisting of fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). Metals tend to have 3 or less valence electrons. 1 decade ago. Meanwhile, the number of valence electrons present also helps us determine a specific element’s chemical properties, such as its valence or valency, the formation of bonds with other elements. Each s sub-shell holds at most 2 electrons, while p sub-shell holds 6, d sub-shells hold 10 electrons, followed by f which holds 14 and finally g which holds 18 electrons.
