Answer:
Cations are ions that are positively charged. They form when they lose an electron because they would have more protons than electrons. In your problem you have for example potassium (number three).
Iodine is a cation because it lost one electron. The ion symbol then would be:
I ⁺
So this is your clue. If it has a positive or a plus sign on top, that would make it a cation. Another clue would be if it LOST an electron, then it is a cation.
An anion, on the other hand, is negatively charged, because they gain electrons, making the electrons more than the protons. In your problem, you have Iodine as an example (number one).
Iodine gained one electron and the ion symbol would be:
I⁻
So again that is your clue for anions, they have a negative or a minus sign on top of the symbol. If they GAINED an electron, that would make them an anion.
Naming monoatomic anions is easy. They are named with the suffix -ide at the end. (Cations retain their name). For example Sulfur (number two).
Sulfur is an anion that gained two electrons with an ion symbol of:
S²⁻
So from the name <u>Sulfur</u><u> </u>the name will change into "Sulfide" and its name will now be <u>Sulfide ion. </u>
<span>The part of a plant that has the potential to produce a lateral shoot is B. auxiliary bud. Auxiliary buds aren't the most relevant buds on a plant, thus they got their name, but they can give rise to a shoot that is formed on the sides of a plant. Apical bud is the primary bud, and cannot do so. Terminal buds are also dominant.</span>
Eutrophication occurs due to excessive use of these compounds, which can lead to having dead zones in bodies of water.
Dead zones refers to areas with decreased levels of oxygen in the bodies of water caused by eutrophication and other factors. These affect the marine life negatively as fishes are also dependent on oxygen.
Eutrophication is defined as the presence of excess minerals in the water, which causes dense growth of plants and leads to depletion of oxygen that make the animals in the water to die.
