Reading and Discussing an Article about Making a Homemade Voltaic Cell In the space provided, describe your sketch using terms you have learned in the lesson.​

The following should be included in your description

• Zinc is the anode, and copper is the cathode

• The lemon flesh and juice provide the salt bridge and electrolyte solution

• Electrons flow from zinc to copper through the external wires

• Electrolytes flow in the lemon. Positive ions (cations) moved toward copper electrodes (cathodes), and negative ions (anions) move toward zinc electrodes (anodes). These balance the charges building up

• Two cells in series provide more energy output than one. The clock may need more energy than can be supplied by one cell

• Batteries do not need external source of reactants, whereas a fuel cell must be supplied with reactants

Explanation: Edg 2021

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.
