Which type of bonding is responsible for holding metal ions together in a metal lattice?
A
Metallic bonding
B
Hydrogen bonding
C
Ionic bonding
D
Covalent bonding
Verified step by step guidance1
Understand that in a metal lattice, metal atoms lose some of their electrons, which become delocalized and free to move throughout the structure.
Recognize that this sea of delocalized electrons creates an electrostatic attraction between the positively charged metal ions and the negatively charged electrons.
Identify this type of bonding as metallic bonding, which is distinct from ionic, covalent, or hydrogen bonding.
Recall that ionic bonding occurs between metals and nonmetals involving electron transfer, covalent bonding involves sharing electrons between nonmetals, and hydrogen bonding is a special dipole-dipole interaction involving hydrogen.
Conclude that the bonding responsible for holding metal ions together in a metal lattice is metallic bonding due to the delocalized electrons acting as a glue.
