Chemistry

the metal on which electroplating is to be done is taken as cathode ( negative electrode) . the metal of which electroplating is to be done is taken as anode ( positive electrode) and the salt solution of the metal of which electroplating is to be done is taken as electrolyte .

example-

if we want to electroplate iron with copper then iron is taken as cathode and copper is taken as anode and electrolyte is copper sulphate.Electroplating is the process of plating one metal onto another by hydrolysis, most commonly for decorative purposes. This is done through the use of copper in a copper sulfate bath.

a numbering system for the periodic table.

Or a trend that periodically shows up.

The energy required to remove an electron from an atom

electrons that are closet to the nucleus

A full octet makes the noble gases nonreactive.

More protons in the nucleus pull the electrons in, making the atomic radius smaller.

From the elements given, argon shows the least reactivity.

Helium has the highest first ionization energy and francium has the lowest first ionization energy.

In this case the yield is 77,27 %.

Barium(Ba)

magnesium (Mg)
