Potassium is represented by the symbol K and the atomic number 19, which also represents how many protons the element has. It is a silvery-gray alkali metal in group 1 on the periodic table.Answer and Explanation: The electronegativity of potassium is 0.82 Pauling units. This is on the Paul...
number of protons, neutrons, and electrons in the neutral atom c. number of valence electrons d. tendency to gain or lose valence electrons e. charge on the ion Judging by its electron configuration and its location on the periodic table, how many valence electrons does chlor...
(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...
8,1 87Francium2,8,18,32,18,8,1 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
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 atom's element is identified by the number of protons.Ans...
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....
