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.
Historically, however, China-North Korean relations have never been significantly affected by North Koreaâs nuclear programs. When North Korea launched the Taepodong-1 missile in 1998, an international outcry for sanctions ensued. Less than two years later, Kim Jong-il visited China in secret.
