An electron source is a bond or a lone pair of electrons. It is either a p bond or a lone pair on an atom of relatively high electron density in a molecule or ion, or a bond that must break during a reaction. An electron sink is an atom on a molecule or ion that can accept a new bond or lone pair of electrons.
What Military Threat Does North Korea Pose? It is impossible to say whether the recent threats from North Korea constitute a clear and immediate danger or whether the strong threats are just bluster in order to extract food aid and technical assistance from the international community.
North Korea is an isolated, impoverished, impulsive rogue nuclear state ruled by a family that has built one of the most terrifying personality cults the world has ever seen. As result, Pyongyang doesn't have a lot of friends. The one country that North Korea can depend on is China. Beijing provides Pyongyang with much of its food and weapons â and is bound by treaty to support the North in the event of war with South Korea. China and North Korea have a reputation for being closely aligned, both militarily and ideologically.
