Atoms gain electrons to form anions.

Atoms lose electrons to form cations.

Back in middle school, my chemistry teacher taught me a good way to remember whether an ion was a cation or an anion. When an atom loses an electron, it becomes positive, and when an atom gains an electron, it becomes negative.

Cation sort of sounds like “cat,” which is positive (Yay! Cats!).

Anions, on the other hand, sounds like “onion,” which is negative (Ew! Onions!).

There’s other ways of memorizing it, but this way was the easiest for me.

sleet_krkn [62]

Answer:

P. aeruginosa

Explanation:

<em>P. aeruginosa</em> is a gram-negative bacteria that belongs to the family Pseudomonadaceae.

From the given question the following points lead us to conclude that the colony that will be growing would be of P. aeruginosa :

1. Flat spreading colonies with a metallic sheen on SBA - <em>P. aeruginosa</em> is known to produce smooth colonies with flat edges.

2. Fluorescent green color in the media with clear colonies on cetrimide agar - <em>P. aeruginosa</em> is known to produce pyoverdin which is a fluorescent pigment under low iron conditions.

3. Medium clear colonies that have a "fruity or grape-like odor" on MacConkey Agar - <em>P. aeruginosa</em> has a sweet fruity odor which is its characteristic odor because of the production of trimethylamine.

Thus, from all these characteristics one can conclude that the organism in the culture is <em>P. aeruginosa. </em>
