Question

some patterns of electron configuration are listed below. in each case, g stands for a noble - gas core and n, m, or o stand for integer numbers like 1, 2, 3 and so on. note: assume g is lighter than rn. think about the chemical elements made of atoms with an electron configuration that matches each pattern. in what block or blocks of the periodic table would these elements lie? would they be metals, nonmetals, metalloids, some of each? use your answers to these questions to complete the table. your answer electron configuration of atoms location of elements (check all that apply) blocks metals or nonmetals? gns^2md^10np^2 s p metals nonmetals d f metalloids gns^2 s p metals nonmetals d f metalloids gns^2md^10np^5 s p metals nonmetals d f metalloids

Explanation:

Step1: Analyze [G]$ns^{2}md^{10}np^{2}$

Elements with this electron - configuration have their outermost electrons in the p - orbital after having filled the d - orbitals. This places them in the p - block. Some of these elements are non - metals (e.g., silicon) and some are metalloids (e.g., germanium).

Step2: Analyze [G]$ns^{2}$

Elements with this electron - configuration have their outermost electrons in the s - orbital. They are in the s - block. These elements are metals, such as the alkaline earth metals.

Step3: Analyze [G]$ns^{2}md^{10}np^{5}$

Elements with this electron - configuration have their outermost electrons in the p - orbital. They are in the p - block. These elements are non - metals, such as the halogens.

Answer:

electron configuration of atoms	location of elements (blocks)	metals or nonmetals?
[G]$ns^{2}$	s	metals
[G]$ns^{2}md^{10}np^{5}$	p	nonmetals
