aThe number of electrons should be filled in second, third and fourth energy level for the argon element.
Answer to Problem 42R
The number of electrons in the 2nd, 3rd, and 4th energy levels of the argon element with atomic number 18 are 8, 8, and zero respectively. The table is given as,
Explanation of Solution
Introduction:
As the distance between the energy level and the nucleus is increased then the amount of energy of the electrons also increases which means that, the electrons present in the energy level close to the nucleus have very little energy as compared to the electrons in the energy levels farther away.
The electronic configuration of the argon with atomic number 18 is,
Here, total 8 electrons are present in the outermost level for
Conclusion:
The electrons in the second energy level is 8 and electrons in third level is also 8 but in forth level, no electron is present there.
