which orbital diagram represents helium (atomic number 2)?
which orbital diagram represents helium (atomic number 2)?
Answer
Brief Explanation:
Helium has an atomic number of 2. Its electron - configuration is 1s². The 1s orbital is filled with 2 electrons with opposite spins. There are no electrons in the 2s or 2p orbitals. The correct orbital diagram should show two electrons with opposite spins in the 1s orbital and empty 2s and 2p orbitals.
Answer:
The orbital diagram with two electrons with opposite spins in the 1s orbital and empty 2s and 2p orbitals.
