86198Rn => 24He + 84194Po
The radon is shown on the left, and the alpha particle, which is a helium nucleus, is shown of the right with the polonium.
In the case when the orbital radius of the electron increases so potential energy should be increased.
<h3>What is the effect of electric potential energy of electron on proton ?</h3>
When there is an increment in the orbital radius of the electron so it represents the distance via the nucleus of increment of the hydrogen atom. And, this nucleus should be considered as positively charged.
The equation for potential energy should be
= Ze²÷ -r Here
Z be the atomic number and, r be the radius
Here the negative sign represents the electron i.e. revolving should be bounded to the nucleus. Also, the relationship between the radius and the potential energy should be inversely proportional.

Answer:
0.22L of H2
Explanation:
We'll begin by writing the balanced equation for the reaction. This is given below:
Fe3O4 + H2 —> 3FeO + H2O
Next, we shall determine the number of mole present in 2.3g of Fe3O4. This is illustrated below:
Molar mass of Fe3O4 = (56x3) + (16x4) = 232g/mol
Mass of Fe3O4 = 2.3g
Mole of Fe3O4 =..?
Mole = Mass/Molar Mass
Mole of Fe3O4 = 2.3/232 = 9.91x10^-3 mole.
Next, we shall determine the number of mole H2 needed for the reaction. This is illustrated below :
From the balanced equation above,
1 mole of Fe3O4 reacted with 1 mole of H2.
Therefore, 9.91x10^-3 mole of Fe2O3 will also react with 9.91x10^-3 mole of H2.
Finally, we can obtain the volume of H2 required for the reaction as follow:
1 mole of a gas occupy 22.4L at stp.
Therefore, 9.91x10^-3 mole of H2 will occupy = 9.91x10^-3 x 22.4 = 0.22L
Therefore, 0.22L of H2 is required for the reaction.
