The answer is electrolytes. Strong electrolytes like strong acids, strong bases and salts dissociate completely into ions when dissolved and no neutral molecules are present in their solution. Weak electrolytes like weak acids and weak bases do not completely ionize in water and some neutral molecules are present in their solution, while nonelectrolytes do not dissociate into ions when in solution at all.

The kind of seismic waves travel through the earth are Congressional longitudinal waves and shear transverse waves.
Explanation:
- There are two kinds of seismic waves and they are the Congressional longitudinal waves and shear transverse waves.
- They are called the P waves and S waves when they pass through the earth.
- P waves are the primary because they are the fastest waves whereas S waves are the secondary since they are slower
- P waves move as alternate compressions and dilations along the side of propagation
- S waves move as alternate compression and transverse motion along the perpendicular side of propagation.
<span>A metal is one which ionizes easily and gives electrons whencompared to other elements.
So it should have a lower ionization energy.
Hence we would expect element 2 to be a metal.</span>
