PH is the potential of hydrogen, pH provides a measure of the concentration of hydrogen ion while pOH scale provides the concentration of OH- ions.
pH denotes the negative logarithm of concentration of hydrogen while pOH denotes the negative logarithm of the concentration OH- ions.
Therefore; in this case the pOH= -log (OH-)
= - log (10^-10)
= 10
If the pOH is 10 then the pH of the solution will be 4
<h2>Answer and Explanation </h2>
Nitrogen is present in group 5. It contains 7 electrons and protons. It has 2 electrons in its first shell and 5 electrons in second shell. In order to determine the atomic number of nitrogen, we should know about the number of protons or electrons of the atom.
Atomic number is denoted by Z. Z= number of protons. Hence, nitrogen consists of seven protons as well as seven electrons. Therefore, its atomic number (Z) will also be 7.
an element's name, chemical symbol, atomic number, atomic mass.

Answer:
lose or share electrons in such a way that the outer shells become chemically complete
Explanation:
Most interactions among atoms take place in the outermost shell of each atom. The number of each electron in this shell determines how an atom combines with other atoms to form compounds. When atoms combine they gain, lose or share electrons in such a way that the outer shells become chemically complete.
