Answer;
-Elements, that are metallic (metals)
Experiment;
Metallic minerals contain metal in raw form.Metallic minerals occur in rare, naturally formed concentrations known as mineral deposits.These minerals contain metallic bonds.
Metallic bonding result from atomic nuclei and inner filed electron shells in a sea of electrons made up of unbound valence electrons or not equally shared
Metallic bonding yield minerals that are soft, ductile / malleable, highly conductive due to easily mobile electrons - metals, also non-directional bonding produces high crystal symmetry
Heterozygous is the answer.
