Question

Which type of bond is found between atoms of solid cobalt?

Answer 1

$onic bonds are between metals and non metals, but solid cobalt does not have a non metal, eliminating choice 4 as well. Metallic bonds are bonds between metals, therefore the answer is (3) metallic.✌️$

Answer 2

The type of bond found between atoms of solid cobalt is metallic bonding.

• In metallic bonding, the valence electrons of metal atoms are not tied to individual atoms but are instead free to move throughout the entire solid. This creates a "sea" of mobile electrons that holds the metal ions together in a lattice structure.
• Cobalt is a transition metal that has a relatively high number of valence electrons (two in the 4s subshell and seven in the 3d subshell), which contributes to its strong metallic bonding.
• Metallic bonding is responsible for many of the physical properties of metals, such as high thermal and electrical conductivity, malleability, and ductility. These properties are also observed in cobalt, which is a hard, lustrous, and ductile metal with high melting and boiling points.
• The strength of metallic bonding can be affected by factors such as temperature and the presence of impurities. For example, alloying cobalt with other metals can change its mechanical and magnetic properties.
