Chemical Symbol: When I think of a chemical symbol, I think of a letter used to describe an element. I have prior knowledge of this term from my chemistry class and learning about the periodic table of elements, but when I think of a chemical symbol there are a few things I think of in relation to my nursing practice. Sodium or Na is number eleven on the periodic table of elements. In nursing, almost every time I work, I hang an IV bag of 0.9% normal saline to keep saline levels in a normal range. In the neuro ICU where I work, we hang a lot of concentrated sodium known as 3% sodium, which helps to decrease brain swelling. In everyday life, we are surrounded by chemical symbols. Currently, I’m wearing a gold necklace. Up until this discussion board, I really didn’t think anything of my necklace. But now as I’m writing this discussion board, it occurred to me that I’m wearing a chemical symbol around my neck every day! When I drink a latte, it contains milk. One of the vitamins in milk is calcium, which is number twenty on the periodic table. People describe chemical symbols by their full name, instead of their symbol. Potassium instead of K+ and Na instead of sodium. However, when I’m at work writing notes down, I do use the chemical symbols to symbolize the different elements we use at work, such as Na for sodium. Chemists define chemical symbols as a notion of one or two letters representing a chemical element. When we explain matter at the microscopic level, we need to know which element we are talking about. We can label this either by the chemical symbol from the periodic table or by the full element name. Everyday people may use this term, but generally people don’t think of the periodic table of elements, or chemistry when they’re using the term. Most people don’t think of the chemical symbol when talking about the element, but the full name of the element. Some similarities of a chemical symbol include stating the full name of the element, such as magnesium. Magnesium is used in everyday language and chemists can use the full name of this element to describe it. During this course, I need to remember what some of the symbols can mean, it’s not necessarily always the first two letters of the word, such as Mg for magnesium. This would just be a refresher for me since I have taken chemistry in the past. Also, when talking about the elements, I need to remember the periodic table of elements.
Mass: When I think of mass, my nursing brain automatically things of weight. In nursing, a lot of medications are dosed according to weight, so it’s always important to ensure we are getting an accurate dosing weight. When I took chemistry, mass was extremely important for our experiments. For everyday people, they relate mass to weight; how heavy something is. When we say dumbbells are 10lbs, we think of the weight of the dumbbells, but we don’t always think of the mass of the object. Another way mass is described in everyday life is by large something is. A different word for this would be massive, like there is a massive storm predicted. To chemists, mass is defined as a a measure of the amount of matter that an object contains. At the microscopic level, mass contains protons, neutrons and electrons in the nucleus not seen to the naked eye. There is a huge different between mass in everyday terms and mass in chemistry world. Most people don’t use the word mass, they use the word weight in relation to talking about an object. And the word mass in everyday terms can translate to something large which might not always be the case in chemistry. Some similarities include the definition which loosely translates to the weight of something. For the purpose of this course, I’m going to have to turn off my nursing brain when I think of mass/weight and strictly think of mass in relation to chemistry and knowing how to properly use this term.
