What is represented by the dots in a lewis electron-dot diagram ofan atom of an element in period 2 of the periodic table?
(1) the number of neutrons in the atom(2) the number of protons in the atom(3) the number of valence electrons in the atom(4) the total number of electrons in the atom

Percent ionization for a weak acid (ha) is determined by the following formula: percent ionization=[ha] ionized[ha] initial×100%for strong acids, ionization is nearly complete (100%) at most concentrations. however, for weak acids, the percent ionization changes significantly with concentration. the more diluted the acid is, the greater percent ionization.a certain weak acid, ha, has a ka value of 9.4×10? 7.part acalculate the percent ionization of ha in a 0.10 m solution.part bcalculate the percent ionization of ha in a 0.010 m solution
