Question
Complete the sentences:a Electrons in shell diagrams are arranged in ...b The valence shell of an atom describes ...c The valence shell is important because
Solution
a) Electrons in shell diagrams are arranged in energy levels or shells around the nucleus of an atom.
b) The valence shell of an atom describes the outermost shell of an atom in its uncombined state, which contains the electrons most likely to be involved in reactions.
c) The valence shell is important because it determines how an atom will behave in chemical reactions, specifically how it bonds with other atoms. The electrons in the valence shell are the ones that interact with other atoms to form chemical bonds.
