There is more than one way to do this but I think the simplest is to recognize that the 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 levels are full. If you count that up it adds to 36. I would, with my handy dandy calculator add the electrons shown (start with 36) and look up the atomic number on the periodic table for total electrons.
Identify the neutral element represented by this excited-state electron configuration, then write the ground-state electron configuration for that element. Excited State: 1s2 2s2 2p2 3s1 Element Symbol: ? Ground State: ?
Which of the following electron configurations correspond to an excited state? Identify the atoms and write the ground-state electron configuration where appropriate. If the configuration is a noble gas, enter the noble gas in
Hi! Can somebody please help me with a coupla questions? Thanks loads!!! Describe physical and chemical properties of isotopes of the same element. Given the electron configuration of an element, how can you tell whether it
Element x has the highest first electron affinity in its period, the ground state electron configuration of its common is: [Kr] 5s2 4d10 5p6 Element Y is the second largest element in its period; its valence electron are in
Element X has the highest first electron affinity in its period; the ground state electron configuration of it's most common ion is [Kr] 5s^2 4d^10 5p^6 a Element Y is the second largest element in it's period; it's valence
