Describe the structure and bonding in indium

The structure of indium consists of positive ions/cations and a sea of delocalised electrons attracting each other to form strong metallic bonds. Explanation: ... The metallic bond is the electrostatic forces of attraction between the delocalised electrons and positive ions.

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.
