Answer:
The element with the electron configuration 1s22s22p63s23p64s23d104p2 is Silicon (Si).
Step-by-step explanation:
The electron configuration of an element describes the arrangement of electrons in its atoms. The numbers and letters in the configuration represent the energy levels (n), sublevels (s, p, d, f), and the number of electrons in each sublevel.
In this case, the electron configuration of the element is:
1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p2
Breaking this down, we can see that the element has:
- 2 electrons in the 1s sublevel
- 2 electrons in the 2s sublevel
- 6 electrons in the 2p sublevel
- 2 electrons in the 3s sublevel
- 6 electrons in the 3p sublevel
- 2 electrons in the 4s sublevel
- 10 electrons in the 3d sublevel
- 2 electrons in the 4p sublevel
Based on the number of electrons in the outermost energy level (valence electrons), we can determine that this element is in group 14 of the periodic table. Looking at the periodic table, we can see that the
