Water is a polar solvent and methylbenzene is a non-polar solvent. A polar solvent will have positive and negative charge (in water, oxygen is slightly more negative and the hydrogen is slightly positi...

Metallic bonding forms a closely packed lattice structure of positive ions with delocalized electrons (these are the electrons of the outer shell of the metal atom).

Because these electro...

Atoms are made up of three types of particles: protons, neutrons and electrons.

The relatives charge on each of these particles are as follows: protons = +1, neutrons = 0, electrons = -1<...
