#Ns2 electron configuration full#
Neon, like all noble gases, has a full valence shell. What is the valence shell electron configuration of all the noble gases except for helium? Its electron configuration is (1s^2 2s^2 2p^6 3s^1). Sodium, element number eleven, is the first element in the third period of the periodic table. (Note that the heavier halogens also have filled ( n 1) d 10 subshells, as well as an ( n 2) f 14 subshell for Rn these do not, however, affect their chemistry in any significant way. Keeping this in consideration, what is the electron configuration for noble gases? All have an ns 2 np 5 electron configuration, one electron short of a noble gas electron configuration. T/F: An oxygen atom, having electron configuration 1s 2s 2p, forms a single bond with another oxygen atom. This is the most stable arrangement of electrons, so noble gases rarely react with other elements and form compounds.īeside above, do all noble gases have the same valence electron configuration? T/F: All noble gases have the same valence electron configuration. That's because they have eight valence electrons, which fill their outer energy level.
Noble gases are the least reactive of all elements. Moreover, what are the valence electrons of noble gases? (ii) Elements with this electron configuration have high third ionization energies. Symbol Sn Explaniation : Since, the atomic number of Tin is 50, we have to fill the subshell until we reach the electron count 50. The noble gases are the only non-transition-metal elements that have eight valence electrons in their neutral, ground state configuration, but atoms of other elements can produce a full octet - an outer shell with eight electrons - by gaining or losing electrons. 31) Consider the general valence electron configuration of ns2 and the following statements: (i) Elements with this electron configuration have low second 4 on low I ionization energies. Answer: Main answer : The name of an element having 2 electrons in its 5p subshell in its ground state is Tin.
