d) 1s^2 2s^2 2p^6 3s^2 3p^6 3d^7
a) 1s² 2s³ 2p¹ - The correct electron configuration is: 1s² 2s² 2p¹
b) 1s² 2s² 2p⁶ 3s² 3d⁸ - The electron configuration is correct.
c) 1s³ 2s² 2p⁶ 3s² 3p⁵ 4s¹ - The correct electron configuration is: 1s² 2s² 2p⁶ 3s² 3p⁴ 4s²
d) 1s² 2s² 2p⁶ 3s² 3p⁶ 3d⁷ - The electron configuration is correct.
a) The correct electron configuration is: 1s^2 2s^2 2p^3
b) The correct electron configuration is: 1s^2 2s^2 2p^6 3s^2 3d^10
c) The correct electron configuration is: 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2
d) The correct electron configuration is: 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^7
a) 1s^2 2s^2 2p^3
The correct electron configuration for the element with atomic number 5 should be 1s^2 2s^2 2p^1. The electron configuration represents the distribution of electrons in an atom's orbitals.
To get the electron configuration, you need to follow the Aufbau principle, which states that electrons fill atomic orbitals in order of increasing energy. The orbital filling order is 1s, 2s, 2p, 3s, 3p, and so on.
The "1s^2" represents that the first energy level (n=1) contains two electrons (2) in the 1s orbital. The "2s^2" represents that the second energy level (n=2) contains two electrons (2) in the 2s orbital. Finally, the "2p^1" represents that the second energy level (n=2) contains one electron (1) in the 2p orbital.
b) 1s^2 2s^2 2p^6 3s^2 3p^6 3d^8
The electron configuration is correct for the element with atomic number 30. This element is zinc (Zn).
c) 1s^2 2s^2 2p^6 3s^2 3p^3 4s^1
In this case, the error is in the 3p orbital. The correct electron configuration should be 1s^2 2s^2 2p^6 3s^2 3p^4 4s^1.
d) 1s^2 2s^2 2p^6 3s^2 3p^6 3d^5
The electron configuration is correct for the element with atomic number 32. This element is germanium (Ge).
