there are 19 protons, neutrons and electrons
An atom of potassium should have one dot in its Lewis-dot structure. This dot represents the single valence electron in the outer shell of the potassium atom.
The Lewis structure of K2O consists of two potassium (K) atoms bonding with one oxygen (O) atom. The oxygen atom will form a double bond with one of the potassium atoms, while the other potassium atom will have a single bond with the oxygen atom. This arrangement allows both potassium atoms to have a full outer shell of electrons.

In a neutral atom, the number of electrons is the same as the number of protons. The electronic structure of an atom with five electrons would be 2, 3. The electron configuration would be 1s22s22p1.

Potassium is a metal element. There are 19 electrons in a single atom.
All chemical properties are determined by electronic structure.
A Lewis dot structure for potassium (K) would have one dot, representing its single valence electron.
Protons in potassium are located in the necules
A calcium ion (Ca²⁺) has lost two electrons, resulting in an electronic structure similar to that of argon (Ar), which has 18 electrons. Both Ca²⁺ and Ar have the same electron configuration of 1s² 2s² 2p⁶ 3s² 3p⁶. Therefore, argon is the atom that shares the same electronic structure as a calcium ion.
An ordinary atom of potassium has no charge.An ionized atom of potassium typically has a +1 charge.Different things.
