So what am I suppose to answer here?
Answer:

Explanation:
All are true except the statement that ions are formed by changing the number protons in an atom’s nucleus.
A neutral atom contains the same number of protons (positive charge) and electrons (negative charge).
If there are <em>more electrons than protons</em>, the atom becomes a <em>negative ion</em>.
If there are <em>fewer electrons than protons</em>, the atom becomes a <em>positive ion</em>.
The protons are in the nucleus, where we can’t easily get at them. The <em>electrons are outside the nucleus</em>, so other chemicals can easily get at them and either remove them or add to their number.
<em>Metals</em> have only a few valence electrons, so it is fairly easy to remove them and <em>form positive ions</em>.
Answer:
6
Explanation:
This can be calculated from a general equation from the which the energies of the various spectral lines of hydrogen shown in the image attached. The various series of hydrogen are:
Lyman, Balmer, Paschen,Bracket and Pfund series.
