What is a substance that has lost or gained electrons?
Most atoms have the ability to lose electrons, given the conditions are favorable, e.g. in a chemical reaction, but the ones that loose their electrons easiest are the ones with only a few electrons in their outer shell, such as the alkali metals and alkaline earth metals which only have 1 and two electrons, respectively.
What elements has 2 main energy levels and seven valence electrons?
Alkaline earth elements have two valence electrons Those are the alkaline earth metals, technically referred to as Group 2. They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba) and radium (Ra). Radium has two valence electrons and is in Group 2, but is sometimes left off lists of the alkaline earth metals because it is radioactive. - Soccer_Fanatic18
