Electrolysis can be used to separate a substance into its original components/elements and it was through this process that a number of elements have been discovered and are still produced in today's industry.
Isotopes of any given factor all incorporate the equal variety of protons, so they have the identical atomic wide variety (for example, the atomic wide variety of helium is usually 2). Isotopes of a given factor include exceptional numbers of neutrons, therefore, special isotopes have special mass numbers.
The atoms in a metal are held together by electrostatic forces called metallic bonds.
4:2. You are comparing the coefficients of NH3 and N2
The ratio of the displacement (change in position) of an object divided by the time interval during which the displacement occurred. Velocity is a vector, having both magnitude and direction. Units: m/s (SI), cm/s (cgs), ft/s (U.S. customary system). See instantaneous velocity.
