But when compounds contain
unequal numbers of negatively and positively charged ions, repulsion between atoms with the same charge may drive the structure to become unstable under pressure.
«Since most of the Earth's minerals
contain unequal numbers of positively and negatively charged ions, our work suggests that large quantities of helium might be stored in the Earth's mantle.»
Sexual harassment thrives when there are
unequal numbers of men and women in a field and when there is a strong hierarchy of power within the profession, Urry said, noting that both conditions are prevalent in science and engineering fields and in academia.
«We propose that there is a general driving force for helium to react with ionic compounds as soon as these compounds have
unequal numbers of negatively charged and positively charged ions,» said Miao, PhD.

9Because of the unbalanced nature of the data being analyzed (i.e.,
unequal numbers of observations for the different levels of the classification variables), the General Linear Models procedure in the Statistical Analysis System was used to perform the analyses.
