Potassium's atomic number is 19. A neutral potassium atom would thus have 19 protons and 19 electrons. We're talking about K+, however, so we need to subtract one electron from this, giving us 18.
The number of electrons is 10.
A potassium ion (K+) has 18 electrons. Potassium has 19 electrons in its neutral state, but when it loses one electron to become an ion, it has 18 electrons.
2 electrons in the K shell and 8 electrons in the L shell
This cation has 24 electrons.
The H+ ion has no electrons.
19 Protons and 20 electrons
The K shell of an atom can hold up to 2 electrons.
An electric-neutral K atom has 19 protons and 19 electrons.
A neutral potassium atom has 19 electrons in total and 1 valence electron.
19 electrons, 19 protons and 20 neutrons
The number of electrons is 10.
This is an ionic bond and electrons are donated from the K atom to the Iodine atom
