Explanation:
A small rock falling from a cliff is an example of physical weathering. The process breaks the rock mass into small chips of rocks.
- Weathering is the physical disintegration and chemical decomposition of rocks to form sediments and soils.
- In physical or mechanical weathering, lumps of rocks are broken down into small sizes.
Some of the process involves:
- Pressure release on a rock
- Freezing and thawing
In chemical weathering, a rock undergoes chemical reactions and it becomes weak in the process.
Some of the process involves:
- oxidation
- hydrolysis
- carbonation

"decrease" would be your answer
Its D for the second energy level, but the first energy level is 2.
The quantum model is regarded as the most current model to explain the composition of an atom. The Bohr model and the quantum model are fundamentally different in that the former explains the particle behavior of an electron while the latter explains its dual nature as a wave and a particle.
<h3>
What is the Bohr Model?</h3>
The Bohr model of the atom was put forth by Neil Bohr in 1915. It was developed by altering Rutherford's atomic model. Rutherford demonstrated how a positively charged nucleus is surrounded by negatively charged electrons in his nuclear model of an atom.
The Bohr hypothesis modified the atomic structure model by explaining that electrons move in fixed orbitals (shells) and not anywhere in between. He also demonstrated the fixed energy of each orbit (shell). Bohr added electrons and their many energy levels to Rutherford's revised concept of the atom's nucleus.
In Bohr's theory, there is a tiny, positively charged nucleus that is surrounded by negatively charged electrons that orbit the nucleus. According to Bohr, an electron that is farther from the nucleus has more energy than an electron that is closer to the nucleus.

Answer:
Atomic number
Protons
Explanation:
Elements generally have specific atomic number of protons they are made up of.
An element is a distinct substance that cannot be split-up into simpler substances. Such substance are made up of only one kind of atom.
- Each element has a unique atomic number
- The atomic number is used to differentiate between an element or the other.
- The atomic number is the number of protons in an atom.
