Answer:
<u><em></em></u>
Explanation:
By definition the<em> atomic number </em>of an element is the<em> number of protons.</em>
The protons are the positevely charged particles in the nucleus of the atom.
The atomic number of an element is what uniquely identifies it. There are 118 known elements and all of them are represented in the periodic table. Then, there are 118 different atomic numbers.
The elements are arranged in the periodic table in increasing order ot atomic number.
For instance:
- The element with <em>atomic number</em> 1 is hydrogen (H). It is the first element in the periodic table, located in the upper left corner of the table. It has one <em>proton</em>. NONE other element has just one proton.
- The element with <em>atomic number</em> 2 is helium (He). It has two <em>protons</em>, is located at the upper right corner of the periodic table and NONE other element has just two protons.
- The element with <em>atomic number</em> 118 is Oganesson (Og). It is the last element in the periodic table. It is located in the bottom right corner of the periodic table. It has 118 <em>protons</em> and NONE other element has atomic number 118.
Answer: $450
Explanation:
Total tickets purchased = 2
The cost of one ticket three months ago = $100
Current price of one ticket = $225
Total cost of two tickets = $225 × 2
= $450
The opportunity cost is the benefit that is foregone by selecting some other alternative. So, here two options are available that either attend the concert or resell the ticket at $450. Therefore, the opportunity cost of attending the concert is $450.

Answer:
The correct answer is letter "C": in color.
Explanation:
In order to make a sentence more concise, it is better to avoid redundancies, it is setting aside words that have a similar meaning within the same segment. Redundancies are typically useful for literature when the author wants to emphasize the meaning of something. Though, when talking about scientific facts, it is better not to use them because they tend to confuse the meaning of the message delivered. In:
<em>When the scientists added the final chemical into test tube, the malodorous liquid turned green in color.
</em>
"...in color" does not add meaning to the message. If something turns green it is understood that the color has changed. Thus, to make more concise the sentence we should delete it.
