Answer:
true
Explanation: chlorine is an element that exists in nature as a diatomic molecule.
Answer:
(σ2s)2(σ2s*)2(σ2p)2(π2p)4(π2p*)2(π2p*)1
Explanation:
In writing molecular orbital configuration, the number of valence electrons involved in the molecule are all written into various molecular orbitals in accordance with the Aufbau principle.
O2^- contains 17 electrons. Its molecular orbital configuration is KK(σ2s)2(σ2s*)2(σ2p)2(π2p)4(π2p*)2(π2p*)1. Recall that the inner (σ1s)2 and (σ1s*)2 is designated as KK. This inner shell does not take part in bonding. The bond order in O2^- is 1.5.
It is true. Since it is very reactive with oxygen and water, it is kept in kerosene or some other some other oil
