<p>Hi can somebody please help me with the following chem questions? I'm stuck on these...</p>
<ol>
<li><p>What common characteristics do the lines in the Balmer series have?</p></li>
<li><p>Fundamentally, why must all the lines in the hydrogen spectrum between 250 and 700nm belong to the Balmer series?</p></li>
<li><p>In the normal, hydrogen atom the electron is in the lowest energy state, which is the ground state. The maximum electronic energy that a hydrogen atom can have is 0 kJ/mole at which point the electron would essentially be removed from the atom and it would become a H+ ion. How much energy in kJ/moles does it take to ionize a H atom?
The ionization energy of hydrogen is often expressed in units other than kJ/mole. What would it be in J/atom? </p></li>
</ol>
<p>thanks so much!</p>
