Answer:
n = 2 to n = 1
Explanation:
The electrons in the closest orbitals to the atomic nucleus experience the strongest attraction. Therefore, for an electron to jump up from the ground state to n = 2 a lot of energy is required to overcome the attractive force of the nucleus (also means this energy will be dispensed when the electron jumps down). The energy required to jump up to other energy levels decreases as these orbitals are shielded from the attractive force of the nucleus.
Explosives are made up of gunpowder
False. Carbon 14 will not be a good means of assigning absolute ages to very old (billions of years or more) igneous rocks.
<h3>What is carbon-14 dating?</h3>
Certain archeological relics of biological origin can have their age estimated by carbon-14 dating up to 50,000 years old. It is used to date items made relatively recently by human activity, such as bone, fabric, wood, and plant fibers. Every day, a lot of cosmic rays penetrate the earth's atmosphere. For instance, every individual receives roughly 500,000 cosmic rays every hour. It happens frequently that a cosmic ray will strike an atom in the atmosphere, producing an energetic neutron as a secondary cosmic ray. These powerful neutrons will then strike nitrogen atoms.
