Potassium atoms have 19 electrons and 19 protons with one valence electron in the outer shell. It is so soft that it can be easily cut with a knife. The atomic mass for protons and neutrons is the same. 1 8 5 Will sulfur lose or gain electrons to be like a noble gas? 1.) Pestle analysis soft drink industry. Since 1s can only hold two electrons the next 2 electrons for Potassium go in the 2s orbital. From periodic table,we see that the atomic number of potassium is 19. How many isotopes does potassium have? So, you have the following electronic configurations: Tests such as this have been performed with many dowsers over the years, but Mr. Randi still has the \$1, 000, 000. The three naturally occurring isotopes of potassium are 39 K, 40 K and 41 K. 39 K makes up about 93.3% of all naturally occurring potassium, 41 K makes up about 6.7% and the remaining tiny fraction is 40 K. 39 K and 41 K are stable isotopes, but 41 K is actually a radioactive isotope. It is always constant. This means that if you have 1000 atoms of 40 K, 1.2 billion years later you'll have 500, and 1.2 billion years after that you'll have 250.
