Since potassium is a metal in group 1A that is intended to kind a hopeful ion (a cation) through the size of the fee equal to the team number. The charge is because of this +1.

The symbol because that the potassium ion is thus K+ ----K++e-

K has an atomic number of 19, through 19 protons and also 19 electrons in the neutral atom. In order because that the ion to bring a fee of +1 it must have actually 1 much more proton 보다 it walk electrons, therefore the atom must lose 1 electron.

The equation that reflects the ion developing from the neutral atom is therefore: K K+ + e-

Note that chemical equations are constantly written "left side" turns into "right side". The neutral K atom turns into a K+ ion and 1 electron.
