Answer:
B) Co2 cuz in the diagram I see two similar atoms it might be of (oxygen) and the one atom of (carbon)
The last one should be right
Answer: KI, LiBr, MgS,GaN
Explanation:
Ionic sizes are the deciding factor in lattice energy. The smaller the ion, the higher the lattice energy. Since K+> Li+ and I- is larger than Br-, LiBr will have a higher lattice energy. The size of the sulphide ion is much smaller than the nitride ion but the Gallium is much smaller due to lanthanide contraction hence the answer.
Answer:
Cl (Chlorine) and Ar (Argon) have the same ground-state electron configuration.
