Since both numbers contain 2 significant digits the answer will contain 2 significant digits:
Answer: b 1.9 x 104
The answer is calcium chloride.
Atomic particles Because the usually have a chain reaction when blown up
A because chem is so cool and when you do that it equals the correct answer
Energy level and spectral line
Explanation:
The energy levels and their spectral lines are related.
Based on the Bohr's model of the atom, he suggested that electrons occupy specific spherical orbits.
These orbits are called energy levels around the nucleus.
The spectral lines are the different colors emitted by atoms when they absorb or lose energy.
- Electrons can transition between different energy levels when they acquire enough energy that corresponds to that of the energy level
- By doing so, they emit energy in the process and this is seen as visible spectral lines.
- Spectral lines are usually studies in order to gain more information about the properties of atoms.
