12 A potassium isotope can be shown as:39K19What are the numbers of protons, neutrons and electrons in this potassium isotope? A 19 protons, 19 neutrons, 20 electrons B 19 protons, 20 neutrons, 19 electrons C 20 protons, 19 neutrons, 19 electrons D 20 protons, 20 neutrons, 19 electrons...
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.
(A) The left panel, shows the Bohr atomic model for Mg, which brings a visual representation of electrons orbiting around a small nucleus containing 12 protons and 12 neutrons. The last electron shell contains the valence electrons, which are two in this case (Mg valence 2+). That is why...
Does potassium lose or gain electrons?Electrons:Electrons are small mobile subatomic particles that are often in association with atomic nuclei. They contribute very little mass to the atom but each electron has the same amount of charge as the protons in the nucleus.Answer and Explanation: ...
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 ...

Why are electrons, rather than protons, the principal charge carries in a metal wire? Discuss a model that explains why a metal, such as a piece of aluminum foil, is a good electrical conductor. Why is it highly unlikely to find an ion with a charge less than -...
The number of protons in the nucleus of an atom determines the atom's element and provides the atomic number to classify the element. However, the number of neutrons in the nucleus of the atom can vary. Each of these variations is called an isotope of that element....
