What’s the question cuz I’m confused lol
It is called a ionic bond or a electrovalent bond. Hope it helps :)
The answer is electron.
The nucleus of a neutral potassium atom is "surrounded" by electron.
The neutral potassium atom contains equal number of protons and neutrons, and there are 19 electrons and 19 protons while 20 neutrons.
20 protons and 20 neutrons are there in the nucleus while 19 electrons surrounds the nucleus in different orbits .
