Answer:
They have completely filled outermost shell
Explanation:
The noble gases are the rarest and occur in trace amounts in the atmosphere because they have completely filled outermost and this makes them unreactive with other elements.
Elements become abundant as they combine with other species to form compounds.
Noble gases on the other hand have a high level of stability and do not readily combine with other species.
Some of these gases are :
Helium
Neon
Argon
Krypton
Xenon
Radon
They have very high ionization energy and very low electron affinity and so will not readily react.
Answer:
glycerol, pyruvate, glycerol -3-phosphate, dihydroxyacetone phosphate and glucose♡ hope this helps♡
A skateboard coasting on a flat surface slows down and then comes to a stop because the skateboard runs out of energy, and slows down, also, sense it is on a flat surface and not going downhill, it goes slower.
Answer:
Substances have more kinetic energy in the gas state than in the Solid state.
Gas have more kinetic energy as it flows from here and there.It flows really fast as it have less space between the molecules
Solids have less Kinetic energy as it is hard and can't flow so easily like gas . It has tightly packed molecules
Answer:Liquids expand for the same reason, but because the bonds between separate molecules are usually less tight they expand more than solids.
Explanation:Heat causes the molecules to move faster, (heat energy is converted to kinetic energy ) which means that the volume of a gas increases more than the volume of a solid or liquid.
