The atomic radius of a chemical element is a measure of the size of its atom.
The atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.
The atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
The density of salt water is 1.025 kg/liters .
If something becomes magnetized for a short amount of time it is only a matter of time before it isn't magnetic anymore. permeant on the other hand is forever and will never undo itself.
