Step-3: Determine the valence shell and calculate the total electrons The number of electrons per shell of strontium is 2, 8, 18, 8, 2. That is, the first shell of strontium has two electrons, the second shell has eight electrons, 3rd shell has eighteen electrons, 4th shell has eight electrons and the 5th shell has two electrons. We know that strontium atoms have a total of thirty-eight electrons. In this step, the electrons of strontium have to be arranged. Step-2: Need to do electron configuration of strontium That is, the strontium atom has a total of thirty-eight electrons. From the periodic table, we see that the atomic number of strontium is 38. That is, we can finally say that there are electrons equal to the atomic number in the strontium atom. And electrons equal to protons are located outside the nucleus. The atomic number is the number of protons. It is necessary to know the atomic number of strontium elements from the periodic table. To know the atomic number we need to take the help of a periodic table. Position of strontium(Sr) in the periodic table It is not possible to determine the valence electrons without electron configuration. The electron configuration is one of them. The valence electrons have to be determined by following a few steps. How do you calculate the number of valence electrons in a strontium atom? The valence electrons determine the properties of the element and participate in the formation of bonds. The total number of electrons in the last shell after the electron configuration of strontium is called the valence electrons of strontium. ![]() The valence electron is the total number of electrons in the last orbit. Therefore, strontium is an alkaline earth metal. All the elements of group-2 are called alkaline earth metals. What are the valence electrons of strontium? That is, a strontium atom has a total of thirty-eight electrons. Electrons equal to protons are located in a circular shell outside the nucleus. That is, the number of protons in strontium is thirty-eight. ![]() Protons and neutrons are located in the nucleus. The nucleus is located in the center of the atom.
