In the periodic table, the period number indicates
a the number of not showing on the lewis dot diagram’s for elements in that period
b the number of the outer most energy level for elements in that period
c the number of balance electrons four elements in that period
d the reactivity levels for elements in that period

The characteristics of two different types of reactions are shown below: reaction a: electrons are gained by the atoms of an element. reaction b: protons are lost by the atom of an element. which statement is true about the atoms of the elements that participate in the two reactions? their identity changes in both reaction a and reaction b. their identity changes in reaction a but not in reaction b. their identity changes in reaction b but not in reaction a. their identity remains the same in both reaction a and reaction b.
