I think they orbit around the atom
Answer:
Noble gas, any of the seven chemical elements that make up Group 18 (VIIIa) of the periodic table. The elements are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), and oganesson (Og).
Answer: Law of conservation of mass explains these observations.
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products formed must be equal to the mass of reactants taken.
In order to get the same mass on both sides, the atoms of each element must be balanced on both sides of the chemical equation.
Mass of reactants= mass of Mg+ mass of 
= 48 g + 32 g = 80 g
Mass of products = mass of 
= 80 g
Thus mass of reactants is equal to mass of products, thus law of conservation of mass is obeyed.
The phase change that releases the most energy is deposition, when gas turns into a solid. It takes the absorption of energy to melt a solid into a liquid, and even more energy to vaporize the liquid into a gas. Hence, the reverse process (from solid to gas) will result in the greatest release of energy.
Answer: Carbon nanotubes, especially multi walled carbon nanotubes, are so strong because they are a single chain of unbroken covalent carbon-carbon bonds.
