Glucose dissolves in water but doesn't produce ions during dissolution process. Two (positive and negative) electrodes that were hooked up to a light bulb and external source of power were placed in an aqueous solution of glucose. What was observed during experiment?

Explanation:

Glucose is an organic compound that is made up of carbon, hydrogen, oxygen atoms. It is a type of polar molecule because it contains a hydroxyl group. Since the carbon-carbon bond and some other bond that are present in this compound is a covalent bond. When glucose is dissolved in water it does not dissociate into ions. So during the experiment bulb can not light due to the absence of ions. Such types of substances that do not dissociate into ions are knowns as nonelectrolytes such as glucose and some other substances.

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.

explanation:

metals have excess of electrons whereas non-metals have deficiency of electrons. thus, in order to gain stability metals easily donate their electrons to the non-metals.

for example, electronic configuration of sodium is and electronic configuration of phosphorous is .

when a phosphorous atom and sodium atom combine together then sodium will donate is extra one electron to the phosphorous atom. as a result there will be formation of ionic bond between sodium and phosphorous.

the reaction will be as follows.

there, are three sodium sodium atoms and each of them will donate its one extra electron to phosphorous atom. thus, the sub-shell of phosphorous gets completely filled.  

thus, we can conclude that electrons are transferred from atoms of sodium to atoms of phosphorous. this transfer makes the sodium atoms donate one electron and the phosphorous atoms to gain one electron. as a result, the sodium and phosphorus atoms strongly attract each other.
