Question

With the help of bohr's model calculate the second ionization

Answer 1

Answer:

please

Explanation:

. The problem statement, all variables and given/known data

The equation En=-Z2RH/n2 gives the energy (according to the Bohr model) of the energy levels available to an electron in any hydrogen-like atom. Calculate the second ionization energy of He(in J). The second ionization energy of He is the ionization energy of He+.

2. Relevant equations

En=-Z2RH/n2 where RH=2.178x10-18J

Z=2

n=?

3. The attempt at a solution

I don't understand which value I am supposed to use for n. When I look up the second ionization energy of He I find that the answer is 54.4 eV or 8.712x10-18J, which is the answer I get when I input n=1 into the above equation. But it's asking for the second ionization energy of He, so why would I use n=1
