Neils Bohr proposed that an electron is found only in specific circular paths or orbits around the nucleus. Each orbit has a fixed energy and are called energy levels. The nearest electron to the nucleus has the lowest energy level and the farthest is the strongest energy level. The energy of an electron is said to be quantized.
Neils Bohr described that :They orbit the central nucleus in discrete paths.

b. results in "smokers breath."
c. can lead to premature aging.
Smoking marijuana can be as unhealthy as smoking cigarettes and can cause cancer.
a. can cause cancer.
Smoking marijuana can be as unhealthy as smoking cigarettes, and it can cause cancer. Marijuana smoke contains many of the same harmful chemicals as cigarette smoke, including tar, carbon monoxide, and carcinogens. These chemicals can damage DNA and lead to the development of cancer.
In addition to cancer, smoking marijuana can also lead to other health problems, such as respiratory problems, heart disease, and lung infections. It can also impair cognitive function and increase the risk of accidents.
The other options, b. results in "smokers breath" and c. can lead to premature aging, are also possible effects of smoking marijuana, but they are not as serious as cancer.

They are made up of atoms of only one type of element.
They are made up of particles that are arranged in a repeating pattern.
They are made up of a random ratio of elements that are bonded together.
Ionic compounds are made up of particles that are arranged in a repeating pattern. Therefore, the correct option is option C.
A specific class of chemical compound known as an ionic compound is created when two or more atoms share electrons. It is made up of anions, which are negatively charged ions, and cations, which are positively charged ions. Most frequently, ionic compounds are created when a metal interacts with a non-metal. The non-metal atom receives one or more electrons to become an anion during this reaction, whereas the metal atom loses one or more electrons to become a cation. The development of a stable ionic compound happens as a result of the electrostatic forces that draw these oppositely charged ions to one another.
