What property do all of the group 18 elements have that makes them stand out from other elements? they are the only nonmetals that are liquid at room temperature. they are the only nonmetals that are solid at room temperature. they are very likely to bond with any element, whether it is metallic or not. they are very unlikely to bond with any element, whether it is metallic or not.

The right option is; They are very unlikely to bond with any element, whether it is metallic or not.

The group 18 elements are placed in the far right side of the period table. The group contains noble gases which are; argon, helium, xenon, neon, krypton, and radon. The noble gases are unreactive because they have complete octets (valence shell). They are unlikely to bond with any element to form compounds. The noble gases have weak interatomic forces, and high ionization energies which reveal their chemical inertness.

false because ozone (o3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.

global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.

explanation:

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.
