What element is 1s22s22p63s23p64s23d4
The Correct Answer and Explanation is:
The electron configuration 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d⁴ represents the element Titanium (Ti), with the atomic number 22.
Explanation:
To determine which element corresponds to this electron configuration, let’s break it down:
- 1s²: This means two electrons are in the first energy level (n=1), in the s orbital.
- 2s² 2p⁶: This indicates that in the second energy level (n=2), two electrons fill the s orbital (2s²), and six electrons fill the p orbital (2p⁶).
- 3s² 3p⁶: This shows that in the third energy level (n=3), two electrons fill the s orbital (3s²), and six electrons fill the p orbital (3p⁶).
- 4s²: Two electrons occupy the 4s orbital in the fourth energy level (n=4).
- 3d⁴: Four electrons occupy the 3d orbital in the third energy level (n=3).
Total Electrons:
- From 1s², 2s², 2p⁶, 3s², 3p⁶, 4s², and 3d⁴, the total number of electrons is:
- 2 (from 1s²) + 2 (from 2s²) + 6 (from 2p⁶) + 2 (from 3s²) + 6 (from 3p⁶) + 2 (from 4s²) + 4 (from 3d⁴) = 22 electrons.
The atomic number of an element corresponds to the number of electrons in a neutral atom. Since this configuration has 22 electrons, it indicates the element Titanium (Ti), which has an atomic number of 22.
Element Characteristics:
- Titanium (Ti) is a transition metal located in period 4 and group 4 of the periodic table.
- It is commonly known for its strength, low density, and resistance to corrosion, making it valuable in industries such as aerospace and medical implants.
- Titanium is typically found in nature in mineral forms, such as ilmenite and rutile.
Thus, the element with the electron configuration 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d⁴ is Titanium (Ti).
