Final answer:
Elements from Group 4 of the periodic table are most likely to form covalent network solids.
Step-by-step explanation:
The elements from Group 4 of the periodic table are most likely to form covalent network solids. Carbon, silicon, and germanium, which are all in Group 4, have similar chemistries and can form covalent bonds to create solid networks. Carbon, in particular, is known for its ability to form different types of bonds and long chains.
