2014年5月26日 · The electron configuration 1s^2 2s^2 2p^6 3s^2 3p^2 is the element Silicon. The key to deciphering this is to look at the last bit of information of the electron configuration 3p^2. …

For the first part of this answer, I will assume that the word has no duplicate letters. To calculate the amount of permutations of a word, this is as simple as evaluating #n!#, where n is the …

2016年1月14日 · The excited state electron configuration of an atom indicates the promotion of a valence electron to a higher energy state. An electron configuration representing an atom in …

2016年8月4日 · "Al"^(3+): 1s^2 2s^2 2p^6 Your starting point here will be the electron configuration of a neutral aluminium atom, "Al". Aluminium is located in period 3, group 13, …

2014年7月26日 · An excited state means that (typically) the valence electron has moved from its ground state orbital (i.e. lowest available energy) to some other higher energy orbital. So any …

2014年12月17日 · An atom in its lowest energy state is said to be in its ground state. The ground state electron configuration of an atom places its electrons in the lowest energy levels …

2016年10月3日 · [Ne] 3s^2 3p^1 The trick is to start at the next smallest noble gas and then complete the electron configuration as you normally would. Here is a video that explains …
