mbry Ch.98 Ch 152337 com/m 9& Ch.10 Tutorial tron Configurations and the Periodic Table Keset | |Help The highest principal quanturn number of period 3 elements is The valence electrons of group 2A Period 5 elements have an nner electron configuration of Xel Period 4 elements have an ner electron configuration of [A elements are in an s subshell The valence electrons of group 5A The highest principal quantum Period 3 elements have elements are in the 6s subshell. number of period 2 elements is 2 Group 8A elements have sx 2p electrons full outer principal s and p subshels True False Type here to searchExplanation / Answer
The electronic configuration of the element is determined by the number of atoms present in the atom . According to this the position of element in the modern periodic table is related.
So here:
The true statements are :
Period 4 elements have an inner electronic configuration of [Ar]
The valence electrons of group 2A elements are in an s subshell
The highest principal quantum number of period 2 elements is 2.
Period 3 elements have six 2p electrons
Group 8A elements have full outer principal s and p subshells.
False :
The highest principla quantum number of period 3 elements is 4.
Period 5 elements have an inner electron configuration of [Xe]
The valence electrons of group 5A are in the 6s subshell
