How many electrons are there in the 2p orbitals of selenium?<\/p>\n\n\n\n
The correct answer and explanation is:<\/mark><\/strong><\/p>\n\n\n\n Correct Answer:<\/strong> 6 electrons<\/strong><\/p>\n\n\n\n Explanation:<\/strong><\/p>\n\n\n\n To determine the number of electrons in the 2p orbitals of selenium, it is important to first understand the electron configuration of the element.<\/p>\n\n\n\n Selenium (Se) has an atomic number of 34<\/strong>, which means a neutral selenium atom has 34 electrons<\/strong>.<\/p>\n\n\n\n Electrons in an atom occupy energy levels (or shells), and within each energy level are sublevels (s, p, d, f). These are filled in a specific order based on their energy, known as the Aufbau principle<\/strong>. The typical order of filling is:<\/p>\n\n\n\n 1s \u2192 2s \u2192 2p \u2192 3s \u2192 3p \u2192 4s \u2192 3d \u2192 4p \u2192 etc.<\/p>\n\n\n\n So, to write the electron configuration of selenium:<\/p>\n\n\n\n 1s\u00b2 Adding the superscripts gives 2 + 2 + 6 + 2 + 6 + 2 + 10 + 4 = 34 electrons.<\/p>\n\n\n\n Now, focus on the 2p orbital<\/strong>. According to the configuration, 2p\u2076<\/strong> shows that there are 6 electrons<\/strong> in the 2p orbitals of selenium.<\/p>\n\n\n\n The 2p sublevel contains three orbitals: 2px, 2py, and 2pz. Each of these can hold a maximum of 2 electrons, so the 2p sublevel can hold up to 6 electrons total. In selenium, this sublevel is completely filled.<\/p>\n\n\n\n This number does not change regardless of the total electrons in the atom. Electrons always fill the lower energy levels first. Therefore, even though selenium has 34 electrons, only 6 of those reside in the 2p sublevel, and they are the same for all elements with atomic number 10 or higher.<\/p>\n\n\n\n In conclusion, the 2p orbitals in selenium hold 6 electrons<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":" How many electrons are there in the 2p orbitals of selenium?
