What Is a Significant Figure in Chemistry?
What Is a Significant Figure in Chemistry?What is a significant figure in chemistry? Is it possible to reach a level where you are able to add the number to figure to get the value? Can you remember for example when you were a child and you learned about the element of mercury. Now you are a chemist, can you remember what you learned?In any course, you learn the theory, but do you think you know what a number means? At some point you might feel that you really understand what a number means, but then you find that you just don't understand the concept. Is there a way to put a number to something that you may consider to be very important?I think many students will tell you that they feel frustrated by how much their teacher will skip over the basics when teaching in a particular school. You have probably come across teachers who will spend half of the lesson trying to get their students to memorize what the prefixes and suffixes of each element are.I mean the teacher will actually po int at the names of the elements, and then he will compare the lengths of the prefixes and suffixes. It sounds very complicated, doesn't it?The other thing that many people in this class find frustrating is when the teacher will explain how to pronounce each element. I mean if you only learned about how to identify an element in the first place, wouldn't that be better? Wouldn't you rather know how the actual element looks?And yet that is the lesson that most students learn. They are instructed on how to say the name of the element, but they are never taught the actual appearance of the element. They are not even taught the proper place in the periodic table.What is a significant figure in chemistry? I'm going to assume that you will not even consider the question 'what is a significant figure in chemistry?'When you can add the number to figure to get the value, that is a significant figure in chemistry. When you can tell me what a number means, that is a significant figure in chemi stry. A significant figure in chemistry is just one more way that you can really improve your chances of getting a job in the field of chemistry.
