Finding "Mystery Elements" by using the isotope format

Question

I am really confused on numbers 3 and 4 of the chart because of their use of charges. I think number three is Titanium and four is Chlorine, but cannot figure out the electrons or neutrons.

Enter the symbol, number of protons, neutrons and electrons corresponding to each of the following "mystery elements", X.Element	symbol	protons	neutrons	electrons

Answer 1

Even though I am unable to see the images below the first row, the concept of charges can still be explained. Elements with a neutral charge have the same number of protons and neutrons (remember that the number of protons is the atom's elemental identity). The charge of an element determines the number of additional or missing electrons that the element would normally have. Since electrons have a negative charge, titanium with a -3 charge would have an additional 3 electrons bringing the total electrons to 25 (for positive charges, a +1 charged chlorine atom would have 16 electrons, while a neutral chlorine atom has 17 electrons). The number of protons and neutrons are not affected by charge.

(Most abundant isotopes with neutral charges)

Atom, Symbol, Protons, Neutrons, Electrons

Chlorine, Cl, 17, 18, 17

Titanium, Ti, 22, 26, 22
