Electrolysis can be thought of as a redox reaction. Discuss the statement by explaining the changes that take place at the anode and cathode during electrolysis, using an example of a molten ionic compound (potassium chloride) .

Write half equations for the reactions occurring at each electrode.

Hints:

1. Identify metallic and non-metallic substances.
2. What are the charges of a metallic and non metallic ions.
3. Identify which electrode the ions go to.
4. Discuss whether electrons are lost or gained at this electrode.

explanation: no but i do not usually comment

answer by yourhope:

how do models compare to real-world objects?

d. most models represent a real-world object in a simpler way.

: )

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
