An Ionic bond is when you have a metal and a nonmetal element bonded together. In this kind of bonds, the metal atom takes electrons from the nonmetal. on other words, this bond involves the gaining and losing of electrons. The atom that receives the electrons becomes an anion (negatively charged ion) and the one that loses them becomes the cation (positively charged ion)
A covalent bond is a bond created between two nonmetals element. In here, both atoms share the electrons.
Both bonds involve interaction between atoms.
The element that has the lowest mass per nuclear particle and therefore cannot release energy by either fusion or fission is the element Fe or iron. Iron is referred to as a special element due to its nuclear binding energy. A general idea is that you can have nuclear fusion of two elements and get a heavier element only up to the element iron in the periodic table of elements and also you can only have fusion reactions starting from the element next to iron. This is due to the nuclear forces and the electromagnetic force being balanced for the element iron.
The two senses which is require in the chemical compounds be dissolved in solution before they can act as stimulants for these senses are smell and odour.
Stimulant for smell include molecules which are dissolved in the air gas easily, can be easily detected by the odour recepters which are located on the nostrils upon binding. The smell neurons transfer this information to the smell bulb which are located in the forebrain all the olfactory process occur.
The sensation of taste occur when our food is dissolved in the saliva secreted by the salivary gland located below the tongue. This food dissolved in saliva binds with the recepters of the tongue which are located on the taste buds of papillae.
Thus, we concluded that the two senses which is require in the chemical compounds be dissolved in solution before they can act as stimulants for these senses are smell and odour.

Answer:
The main energy levels are the shells where the electron resides in a location that's relative to the atom's nucleus.
Explanation:
In electronic configuration in chemistry, the main energy levels are the shells where the electron resides in a location that's relative to the atom's nucleus. Such an energy level is usually denoted by the principal quantum number n. So n can be 1,2,3,4...e.t.c
