What is the energy of the lowest orbital and why?

[hamza]

Help needed!

Could someone please answer the folloing questions.
Plese do give the explanations too

2- What is the energy of the lowest orbital and why?

3- If an electron makes a transition from 2nd to the first orbital than in which of the following particles will the wavelength of the photon released will be the smallest.
a) Hydrogen atom b) Deutrium atom c) Helium ion d) bipositive lithium ion.

Here we do not give answers to people as a kind of machine. Please use the template:

"1. problem"

"2. info given, equations etc"

"3. attempt to solution"

How can we help someone if we don't know what he/she don't understand? By just giving answers, that is not helping and is against the guidelines for this forum.

The energy of the lowest orbital, also known as the ground state, is determined by the specific quantum numbers of the electron in that orbital. The lowest orbital is the first energy level, or n=1, and has the lowest energy because the electron is closest to the nucleus and experiences the strongest attraction.

If an electron makes a transition from the 2nd to the 1st orbital, the wavelength of the photon released will be the smallest in a hydrogen atom. This is because the energy difference between the 2nd and 1st orbitals is the smallest in a hydrogen atom compared to the other particles listed. The energy difference between orbitals is directly proportional to the wavelength of the photon released, so the smaller the energy difference, the smaller the wavelength.
