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.
Taking out North Koreaâs two major nuclear sites with air strikes would be dangerous but probably not too difficult, U.S. officials say. The possibility of North Korean retaliation against Seoul, South Koreaâs capital of 10 million and only 35 miles from North Korea, would be a complicating factor, they concede. Yet the more advanced North Koreaâs nuclear arsenal becomes, the tougher it will be to dismantle peacefully.
