Protons,Electrons and Neutrons
This page is an exercise in relating the
number of protons, electrons and neutrons for an atom or monoatomic ion. When it
loads (and when you press "Refresh"), a symbol will appear in the first cell and
several other cells will have values. Fill in the empty cells (all of the values
are integers) and press "Check Ans." Results appear in the smaller table. You
need a periodic table or a list of the elements to use this page. If the charge
is positive, just enter the integer. If it's negative make sure you include the
sign.
- If you miss a problem three times, pressing "Show Answer" will cause the
correct answer to appear.
