Answer:
b
Explanation:
on edge
Answer:
"It has five valence electrons available for bonding".
Explanation:
A planet's orbit around a star is an example of an orbit, which is the route taken by an object as it travels around another object under the effect of gravity. On the other hand, an electron orbital relates to the three-dimensional area surrounding an atom's nucleus where there is the greatest chance of encountering an electron.
The route a planet takes as it circles around a star or another astronomical object in space is known as its orbit. It is influenced by the planet's motion and the gravitational attraction of the object it circles. A planet's orbit might be elliptical, which means it is not a complete circle but rather has an elongated shape instead.
Astronomers use the study of planet orbits and their properties to better understand how celestial bodies move through space. An electron orbital is a probability distribution that shows where an electron is most likely to be found within an atom, whereas an orbit is a definite track that a celestial object travels as a result of gravity.
Therefore, a planet's orbit around a star is an example of an orbit, which is the route taken by an object as it travels around another object under the effect of gravity. On the other hand, an electron orbital relates to the three-dimensional area surrounding an atom's nucleus where there is the greatest chance of encountering an electron.

Final Answer:
Three toxicants associated with sewage are heavy metals, organic pollutants, and pathogenic microorganisms.
Explanation:
1. Heavy Metals: Sewage can contain heavy metals such as lead, mercury, and cadmium, which are often discharged into wastewater from industrial processes and urban runoff. These toxic metals can contaminate water bodies, accumulate in aquatic ecosystems, and pose significant health risks to both aquatic life and humans when consumed through contaminated water or seafood.
2. Organic Pollutants:*Sewage also contains a variety of organic pollutants, including pesticides, solvents, and synthetic chemicals. These substances can originate from household products, industrial discharges, and agricultural runoff. Organic pollutants can have adverse effects on aquatic ecosystems by disrupting the balance of the ecosystem, affecting water quality, and harming aquatic organisms.
3. Pathogenic Microorganisms: Sewage is a potential carrier of pathogenic microorganisms such as bacteria, viruses, and parasites. When sewage is improperly treated or discharged into water bodies without adequate disinfection, it can lead to the contamination of drinking water sources and recreational waters, causing waterborne diseases and infections in humans.
Proper sewage treatment and wastewater management are essential to minimize the release of these toxicants into the environment and protect human health and aquatic ecosystems.
