Question

select all the true statements. when electrons are transferred from one metal atom to another metal atom, an ionic bond is formed. metallic bonding occurs between a metal atom and a nonmetal atom. in a metal, valence electrons are shared among all of the atoms in the material. in a metal, valence electrons move freely throughout the entire lattice.

Explanation:

• Ionic bonds form between a metal and a non - metal through electron transfer, not between two metal atoms. So the first statement is false.
• Metallic bonding occurs between metal atoms, not between a metal and a non - metal atom. So the second statement is false.
• In a metal, valence electrons are delocalized and shared among all atoms in the material. This is a key characteristic of metallic bonding. So the third statement is true.
• In a metal, valence electrons move freely throughout the entire lattice (as shown in the electron - sea model with freely moving electrons around metal nuclei). So the fourth statement is true.

Answer:

In a metal, valence electrons are shared among all of the atoms in the material.
In a metal, valence electrons move freely throughout the entire lattice.
