What is the correct formula that would result from the combination
of the two ionic species?
Cs1+ and Ci1-

CsCl

Explanation:

The ionic species are:

            Cs⁺   and Cl⁻

The two ions will combine to form an ionic compound which results from the electrostatic attraction between oppositely charged ions.

Elements or ions exchange directly their combining powers or their simplest whole number ratio during the formation of chemical formulae of compounds

                                Cs⁺   and Cl⁻

Combining power      1             1  

Exchange of

valencies                     1             1

      Compound CsCl

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
