your answer to your question is B
I think answer of this question is D
The ionisation energy increases.
This is because the force of attraction between the electrons and the positive nucleus will increase
The energy of the electron in third energy level.
Explanation: The energy of the electrons depend on the value of n, i.e the value of principal quantum number which tells the shell of the electron.
Z= atomic number
n= principal quantum number
Thus represents the energy of the electron which is present in n=3.
In order to convert the work function of cesium from electronvolts to Joules, we must use the following conversion factor:
In our problem, the work function of cesium is
so, we can convert it into Joules by using the following proportion:
