Draw the potassium atom and show the distribution of electrons in its shell [k=19] ?

The potassium atom has 19 electrons. The electron configuration of potassium is 2-8-8-1, meaning it has 2 electrons in the first shell, 8 electrons in the second shell, 8 electrons in the third shell, and 1 electron in the fourth shell.

Here is a simple representation of the potassium atom with its electron distribution:

K (19)
1st shell: 2 electrons
2nd shell: 8 electrons
3rd shell: 8 electrons
4th shell: 1 electron

Please note that this is a simplified representation and the actual distribution of electrons in an atom is more complex.
