Potassium has 19 protons, 21 neutrons and 19 electrons. One of the many important electrolytes found in the human body is potassium. Potassium is an element expressed by the notation K. Like all electrolytes, potassium is needed to ensure proper function of multiple systems throughout the body....
Mass numbers are used to identify different isotopes of an element and are a count of the protons and neutrons found in that isotope's nucleus. Interestingly, the number of protons will remain constant, regardless of the isotope, but the number of neutrons will change. This is because an ato...
London. He electrolyzed dried potassium hydroxide (potash) which he had very slightly moistened by exposing it to the moist air in his laboratory. The electrolysis was powered by the combined output of three large batteries he had built.
The chemical reactivity of an element is largely determined by a. the number of protons in the nucleus of the atom. b. the number of neutrons in the nucleus of the atom. c. the number of electrons in the outer or Which of ...
1 All of the atoms in alkali metals have one electron in their outer electron shells. To become stable they have to give off one electron to elements with seven electrons in their outer shell making it eight, also stable. Then they become single charged positive ions (cations). Melting ...
