What is the element with 55 protons and electronic trustee of the [Kr] 5S ^ 2 4D ^ 10 5P ^ 6?
I saw the periodic my table too many times and developed configuration, but for the life of me, I just can not figure it out? Please help as I have to figure out the combined with a base thereof + OH and HCl. Thank you very much!
You probably know this: The number of protons determine the identity of the item. 55 after It should be cesium. Atoms with different # Of neutrons are called isotopes, different number of electrons are called ions (not atoms atoms because they must be electrically neutral). Electronic configuration cesium was 1S ^ 2, 2s ^ 2, 2P ^ 6, 3S ^ 2, 3P ^ 6, 4S ^ 2, 3D ^ 10, 4P ^ 6, 5S ^ 2, 4d ^ 10, 5P ^ 6, 6s ^ 1, right? Krypton is 1S ^ 2, 2s ^ 2, 2P ^ 6, 3S ^ 2, 3P ^ 6, 4S ^ 2, 3D ^ 10, 4P ^ 6, right? cesium (aka cesium) can therefore be rewritten [Kr] 5S ^ 2, 5P ^ 6 4d ^ 10, 6s ^ 1. Now, what is the difference between this configuration and you? It seems no one electron, right? If an atom (electrically neutral) loses an electron, but not change its PROTON number / atomic number, it remains the same element, but is loaded. Less negative = More positive, so that by the end ... (think about this response in the next paragraph) (pause) CS (1), which makes sense, since Cs in one group and group elements are reluctant lose electrons because they have lower electronegativities such as Li (1), Na (1), K (1) To be honest, if it is for an item, you can have said: "Fuck the electron configuration; By definition, the identity element depends on the number of protons or cesium that! " but ... I hope I learned something. Success in chemistry!
