3 A specific amount of energy is emitted when excited electrons in an atom in a sample of an element return to the ground state.
This emitted energy can be used to determine the(1) mass of the sample (2) volume of the sample
(3) identity of the element
(4) number of moles of the element
When a specific amount of energy is emitted when excited electrons in an atom in a sample of an element return to the ground state, this emitted energy can <span>be used to determine the "identity of the element".</span>
What happens is,that,when a river flows into the ocean it carries some land with it. This land is made up of rocks and soil, which contains minerals. One of these minerals is Salt.
