Sodium atoms effectively transform into positivelyĬharged sodium ions when all of their valence electrons merge together and form one negatively charged sea of electrons. Sodium is a group 1 element that contains a single valence electron.
The valence electrons of sodium are removed, producing a lattice stabilized by ionic bonding.The valence electrons of sodium atoms are shared, producing diatomic molecules with double covalent bonds.The valence electrons of sodium atoms are shared, producing diatomic molecules with single covalent bonds.The valence electrons of sodium atoms are not involved in bonding.The valence electrons of sodium are delocalized, producing a lattice stabilized by metallic bonding.Which of the following is theīest description of bonding between sodium atoms? Like hydrogen atoms, atoms of sodium each contain a single valence electron. Stable because of the strong attractive electrostatic forces between their metal cations and their negatively charged sea Metallic lattice structures tend to be relatively It isĪlso because valence electrons do not stay close to any one metal cation. This is partly because valence electrons are highly mobile. When they are decoupled from atoms in a metallic lattice. Valence electrons tend to be called delocalized electrons Merge together and form one negatively charged sea of electrons. The sodium atoms are shown to effectively transform into positively charged sodium ions when all of their valence electrons It represents the electrons as blue circles, and the How sodium atoms form a giant metallically bonded lattice. Groupġ element atoms form a metallically bonded lattice because they have a single valence electron. Valence electrons are the electrons of atoms or ions that are located in an outermost electron shell.Įlements usually end up forming a giant metallically bonded lattice if they have a low number of valence electrons. It shows the electron shells of lithium, sodium, and potassium atoms, respectively, from left to right. The following figure shows the electron shells of three group 1 elementĪtoms. Shells of some representative group 1 element atoms. We can better understand valence electrons if we examine the electron They are electrons that do not make up innerĮlectron shells. Valence electronsĪre the electrons of an atom or ion that cannot be classed as core electrons. The bonding properties of any one atom or ion are primarily determined by its number of valence electrons. As such, C, nuclear, is not a type of chemical bonding. Metallic and ionic compounds have metallic and ionic bonding. Covalently bonded compounds have covalent bonding, and Together and form much-larger ionic or metallic compounds. Which of the following is not a type of chemical bonding?Ītoms can group together and form small covalently bonded compounds that contain just a few atoms, or they can group Example 1: Understanding What Is and What Is Not a Chemical Bond
