'''원소의 이온화 에너지'''란 어떤 [[화학 원소]]의 [[기체]] 상태의 [[원자]] 1&nbsp;mol에서 [[전자]] 1&nbsp;mol을 떼어 내는 데 필요한 [[에너지]]를 뜻한다. 보통 [[금속]] [[물질]]의 경우 [[이온화 에너지]]가 작을수록 양이온이 되려는 경향이 강하므로 반응성이 크다. 또한, [[이온화 에너지]]가 작은 [[금속]]일수록 [[전지]]의 음극이 되려는 경향이 강하며, [[전지]]에 사용하는 두 [[금속]]의 [[이온화 에너지]]의 차이가 클수록 전압도 높아진다. 다음의 표는 중성의 [[원자]]에서 하나의 [[전자]]를 떼어내는 데 드는 [[이온화 에너지]]를 나타낸다. 이것이 1차 에너지이다. (''n''&minus;1)개의 전자를 떼어낸 후 ''n''번째 전자를 떼어내는 데 드는 에너지는 ''n''차 에너지이다. 다음의 표에서 이온화 에너지의 단위는 [[줄 (단위)|kJ]]/[[몰 (단위)|mol]]이다.

== 1차 에너지에서 10차 에너지까지 ==
