Cations are formed by losing electrons in the valence shell of atoms. There are more protons than electron ions making the atom more positive.
<span>same no of atoms
b/c
no. of atoms = moles * avogadro's no (6.022 X 10^23)</span>
The last one is the correct answer. The atomic structure can be broken down which is what the findings concerning protons, electrons and neutrons showed. The theory was thus modified. What remained was no chemical reaction could affect the basic structure of an atom.
Still the last choice is still true. The first choice is your second best answer because of what I wrote in the last sentence of the above paragraph.
