K atom has 19 porotns and 19 electrons
K+1 ion has 19 protons and 18 electrons
ions are formed by the loss of electrons OR the gain of electrons, not by changing the protons - so the symbol comes from the 19 protons

The answer for your question is POTASSIUM (K-19) But the electron number for the species is 18 which means that the species loses one electron and become cation so the symbol will be K+.
The atomic number is actualy the proton number so that you can calculate the similar type of question in future.

The chemical Symbol would be K for potassium. Potassium has a positive charge and is an ion found aboundantly in cells.

Just look on the periodic table for number 19 (that's 19 protons) and put one plus sign with it because it has one more proton than it has electons.

K+
(K = potassium) lose an electron it becomes positive.
