An excited electron is in a <em>high-energy state</em>.
When it drops to the lower-level ground state, it must get rid of this excess energy by <em>emitting it</em> as a quantum of light.
Far apart and have weak attractive forces between them
Answer: capsule and fimbriae
Explanation:
Many prokaryotes have sticky outermost layer called the capsule.It is made up of polysaccharides and it helps them clinging to each other or to other surfaces around them.It also helps prevent the cell from drying out.
Fimbriae,also known as attachment pilus,used by bacteria to adhere to one and other,animal cells or to any inanimate objects.
<span>Okay, a mole of potassium perchlorate contains 6.02x1023 formula units of potassium perchlorate, but you're asking about individual atoms. So, let's look at the formula: KClO3. That's 1 potassium, 1 chlorine, and 3 oxygens, for a total of 5 atoms per formula unit. Now, multiple 5 by Avogadro's number above, to get 30.1x1023, which simplifies to 3.01x1024 atoms.</span>
