Answer:

d. Metallic

c. S

Explanation:

A metallic bond is an interatomic bond in which valence electrons are constantly moving between atoms like a sea of electrons.

  • The formation of this bond type is favored by a large atomic radius, low ionization energy, and a large number of electrons in the valence shell.
  • The metallic bond is an attraction between the positive nuclei of all the closely packed atoms in the lattice and the electron cloud jointly formed by all the atoms losing their outermost shell electrons.

2. The bond type described in the second problem is an ionic bond. This results in the formation of crystal lattice with strong bonds.

  • It occurs between metals and non-metals
  • Since Nickel is a metal, sulfur is the only given non-metal that will make it form an ionic bond.
