A. what are substances called whose water solutions conduct electricity? b. why does a salt solution conduct electricity? c. why does a sugar-water solution not conduct electricity?

A. If a substance dissociates in water solution on ions, its water solution conduct electricity
B.  salt  dissociates in water solution on ions,so  its water solution conduct electricity
C. sugar does not  dissociates in water solution on ions,so  its water solution does not conduct electricity

If a hydrogen atom is neutral, it must also have  one electron. an oxygen atom (o) has an atomic number of eight (8). this means a neutral oxygen atom has eight protons and eight electrons. the element actium (ac) has an atomic number of 89, so it has 89 protons and 89 electrons in a neutral atom
