Question

Gizmo Warm-up Just like students sharing markers, atoms sometimes share or swap electrons. By doing this, atoms form bonds. The Ionic Bonds Gizmo allows you to explore how ionic bonds form. To begin, check that Sodium (Na) and Chlorine (Cl) are selected from the menus at right. Click Play ( ) to see electrons orbiting the nucleus of each atom. (Note: These atom models are simplified and not meant to be realistic.) 1. Each atom consists of a central nucleus and several shells that contain electrons. The outermost electrons are called valence electrons. How many valence electrons does each atom have

    Answer: Sodium element has 1 valence electron and chlorine element has 7 valence electrons.

    Explanation:

    Valence electrons are defined as the electrons that are present in the outermost shell.

    An ionic compound is formed when the complete transfer of electrons takes place from one element (usually metals) to another element (usually non-metals).

    To know this, we need to write the electronic configuration of each element.

    Sodium is the 11th element of the periodic table and has an electronic configuration of 1s^22s^22p^63s^1

    It has 1 valence electron

    Chlorine is the 17th element of the periodic table and has an electronic configuration of 1s^22s^22p^63s^23p^5

    It has 7 valence electrons

    Hence, sodium element has 1 valence electron and chlorine element has 7 valence electrons.
