The electron configuration you provided, 1s2 2s2 2p6 3s2 3p6, represents the electron configuration of an element. To determine the element, we need to count the total number of electrons and match it to the corresponding element on the periodic table.
Let's break down the electron configuration:
1s2 -> This indicates that there are 2 electrons in the 1s subshell.
2s2 -> This indicates that there are 2 electrons in the 2s subshell.
2p6 -> This indicates that there are 6 electrons in the 2p subshell.
3s2 -> This indicates that there are 2 electrons in the 3s subshell.
3p6 -> This indicates that there are 6 electrons in the 3p subshell.
Now, let's add up the total number of electrons:
2 + 2 + 6 + 2 + 6 = 18
So, the element with this electron configuration has 18 electrons.
To find the element, we can refer to the periodic table and locate the element with 18 electrons. The element with 18 electrons is argon (Ar), which has the atomic number 18.
