Jun 13, 2017 · See a solution process below: 3P1 = (3!)/((3- 1)!) = (3!)/(2!) = 3

When looking at electron configuration, your fill order of electrons is:. 1s 2s 2p 3s 3p 3d 4s 4p 4d 4f

May 26, 2014 · 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. The '3' informs us that the element is in the 3rd Energy Level or row of the periodic table. The 'p' tells us that the element is found in the p-block which are all …

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 amount of letters.

Jan 14, 2016 · 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 the excited state will show a valence electron promoted to a higher energy level. Example The ground state electron configuration of sodium is "1s"^2"2s"^2"2p"^6"3s"^1. In its excited state, the valence electron in the "3s ...

Aug 4, 2016 · "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, and has an atomic number equal to 13. This tells you that the electron configuration of a neutral aluminium atom must account for a total of 13 electrons. The electron configuration of the neutral atom looks like this "Al: " 1s^2 ...

Jul 26, 2014 · 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 electron configuration in which the last electron (again, the valence electron) is in a higher energy orbital, this element is said to be in an excited state. For example, if we look at the ground state (electrons in the ...

Dec 17, 2014 · 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 possible, and the electrons are ordered according to increasing energy levels, sublevels, and orbitals. In order to determine how many electrons are in a neutral atom of an element, we need to find the atomic number of the ...

Oct 3, 2016 · [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 further... Hope this helps!

Sodium (Na) The outer electrons are on the 3rd energy level sub-shell (due to the 3s^{1} Thus we can deduce that the element is in the third period of the periodic table. There are 1 electrons in total in the final sub-shell (adding all the powers of the 3'rd level) This means it's in group 1. From this we can deduce it being Na (Sodium)
