Problem 03 1 point possible (graded) Which of the following is not a correct ground state electron configuration? O 1s 2s 2p4 O 152252352 O 1s 2s 2p6 O 1s 2s 2p 3s Submit You have used 0 of 1 attempt Save The image shows a representation of an atom, showing the position of the nucleus can be defined, but the size of an electron orbital cannot be well defined. We have said that defining the size of an atom is difficult, because atoms are not hard spheres, the wavefunction of the electrons extend away from the nucleus infinitely. However, we can define the position of the nucleus, where the protons and neutrons are, with quite a lot of certainty, it is the electrons that give us trouble. Why can we determine the position of the nucleus much more accurately than the edge of the electron orbital? Because of the negative charge on the electron Because the nucleus contains both protons and neutrons Because protons and neutrons are a lot heavier than electrons Because the electrons can be in multiple different orbitals Submit You have used 0 of 1 attempt Save The image shows an atom-level representation of concrete. Concrete is the single most widely used material in the world. There is no structural engineering without concrete. Given the list of options, select the correct answer to this question: Is concrete monoatomic? O Yes O No
