What is a chemical symbol trying to portray?

Explanation:

Think of all the symbols and shorthand ways we represent things in our daily lives. A common example of a symbol that you use every day is an emoticon on your cell phone. You use a smiley face to indicate that you are pleased about something. You don't text 'I'm pleased about that'; instead, you just insert a smiley face. You may also use a shorthand version of your name, a nickname, like Bill instead of using the longer version of your name, William.

Chemical symbols are used in much the same way. A chemical symbol is a shorthand method of representing an element. Instead of writing out the name of an element, we represent an element name with one or two letters.

As you know, the periodic table is a chemist's easy reference guide. As shown below, the periodic table contains the elements arranged by size of the atom that makes up the element and the properties of those atoms. Each element is represented by a chemical symbol consisting of letters. Examples of chemical symbols are shown in the next section.

So what are the origins of these chemical symbols? As early chemists (known as alchemists back then) discovered the fascinating world of chemistry, they often symbolized their newly discovered elements by weird icons, like the one shown here.

Alchemy Symbols

Compare these weird symbols to the ones used for these elements today:

1. Tin- Sn (from the Latin word, stannum)

2. Lead- Pb (from the Latin word, plumbus)

3. Gold- Au (from the Latin word, aurum)

4. Sulfur- S (from the Latin word, sulfurium)

5. Mercury- Hg (from the Latin word, hydrargyrum meaning 'liquid silver')

6. Silver- Ag (from the Latin word argentum)

7. Iron- Fe (from the Latin word ferrum)

All of these 118 elements on the periodic table have chemical symbols represented by the first letter or two of the name of the element. If the chemical symbol has two letters the first letter is always capitalized and the second letter is written in lowercase. For chemical symbols that consist of one letter, that letter is always capitalized. For example, C represents carbon, Ca for calcium, O for oxygen.

the correct answer is answer a. a mixture

no other options make sense

hope this
