Q
Q: Which of the following statements about the electron configuration of an atom is correct?
Solution:
Electrons fill orbitals in order of increasing energy, and the 4s orbital is filled before the 3d orbital.
Steps: 5
Show Steps
Step 1: Understand that electrons are found in orbitals around the nucleus of an atom.
Step 2: Know that orbitals have different energy levels, and they fill in a specific order.
Step 3: Learn the order in which orbitals are filled: 1s, 2s, 2p, 3s, 3p, 4s, 3d, and so on.
Step 4: Notice that the 4s orbital is filled before the 3d orbital, even though 3d has a higher principal quantum number.
Step 5: Conclude that the statement about the 4s filling before the 3d is correct.
