Based on the chemical equation, use the drop-down menu to choose the coefficients that will balance the chemical equation:
()Li2O + ()H2O → ()LiOH

n has four pairs of electrons in the valence shell, electrons repel one another ,n has 7 protons in its nucleus, and since n has 7 protons, it must fill the second shell, giving it 4 pairs of electrons. the electrons form 3 bonds and 1 lone pair of electrons. each pair of electrons repels the other pairs, so they are equally far apart.

so all of the above

for points guys
