What element corresponds to 1s22s22p63s23p64s23d104p6?
The element that corresponds to this electron configuration is Argon (Ar).
To determine the element corresponding to the electron configuration 1s22s22p63s23p64s23d104p6, we need to count the number of electrons.
Let's break down the electron configuration:
1s2 represents the first energy level with 2 electrons.
2s2 represents the second energy level with 2 electrons.
2p6 represents the second energy level with 6 electrons.
3s2 represents the third energy level with 2 electrons.
3p6 represents the third energy level with 6 electrons.
4s2 represents the fourth energy level with 2 electrons.
3d10 represents the third energy level with 10 electrons.
4p6 represents the fourth energy level with 6 electrons.
Adding up the total number of electrons: 2 + 2 + 6 + 2 + 6 + 2 + 10 + 6 = 36.
36 electrons correspond to the element Krypton (Kr), which has atomic number 36.
To determine which element corresponds to the electron configuration 1s22s22p63s23p64s23d104p6, we look at the periodic table.
1s22s22p63s23p64s23d104p6 represents the electron configuration of an atom with all its electrons filled up to the 4p orbital. This corresponds to the 18th group (group 18 or Group 0) of the periodic table, which is known as the noble gases.
More specifically, the electron configuration is that of the noble gas neon (Ne). Neon has 10 electrons in its 1s, 2s, 2p, 3s, and 3p orbitals. The addition of another 10 electrons in the 4s, 3d, and 4p orbitals completes the electron configuration of the element.
Therefore, the element with the given electron configuration is neon (Ne).
