the atom in its lowest energy state is said to be in __________ state and when it absorbs energy it is said to be in __________ state.

1. ground, excited
2. lower, higher
3. inactive, active
4. none of the above

Explanation:

In atomic physics (a subfield of Physics, under Natural Science), an atom's lowest energy state is called the ground state. When it absorbs energy, it moves to a higher - energy state known as the excited state. Option 2 uses general terms for energy levels but not the specific atomic state terms. Option 3's terms (inactive, active) are not used to describe atomic energy states. So the correct terms are ground and excited.

Answer:

1. Ground, Excited
