“Models are developed when a scientist’s creativity and insight are combined with data and observations about many similar scenarios”. Models are used for a lot of things in science. As we know everything has advantages and disadvantages, and the same applies to models. Models help us illustrate the concept and formulate hypothesis. When models are used, the scientists are able to notice patterns and develop and revise representation that become a useful model, which makes their scientific knowledge stronger and helps them understand more about the nature of science. Models are a simplified representation. One of the biggest advantages of the model is, that it allows you to have a look at things which are too small such as atoms or too big such as the solar system.
Although, having many benefits, models have quite a number of disadvantages. Models sometimes oversimplify the process therefore leading to a misunderstanding. As models are supposed to be a simplified representation, they will not be complex, which means they will lack detail. For Example “our particle model explains many things about matter, it is not comprehensive — for example, it cannot predict why certain materials have different electrical properties. We could add further refinements that are outside the scope of this course to enable it to do so, but it would make our model so complicated that it would no longer be useful to us”
It's called 'static electricity,' and it happens when a few electrons get pulled off the atoms in your hair and onto your hat. That leaves your hair with not quite enough electrons. ... Positive charges repel each other, so your charged hairs repel each other and stand out from your head.
The Match of element to its name, atomic mass is as below
element symbol atomic mass or atomic number
Antimony Sb 51
sulfur S 32
Silicon Si 14
<u><em>Explanation</em></u>
From periodic table Antimony is a chemical element with symbol Sb and atomic number 51.
Sulfur on the other hand is a chemical element with symbol S and has a atomic mass of 32
silicon is an element with symbol Si and atomic number 14
