Concept explainers
Fill in the names beside the symbols of the following elements commonly found in living matter.
To fill: The names beside the symbol of the given element that are commonly found in living matter.
Introduction: In the simplest level of organization, the human body consists of various chemical structures. The substances that cannot be broken down into simpler substances by ordinary chemical reactions are called elements. Every element has its own chemical symbol.
Answer to Problem 1IQ
Tabular representation: The names of the symbol of the given element are in Table 1.
Table 1: Names of the symbol of the given element
Ca -Calcium | Na- Sodium |
P- Phosphorus | Cl- Chlorine |
K- Potassium | Mg- Magnesium |
S- Sulfur |
Explanation of Solution
Chemical elements are represented as symbols. In general, first one or two letters of element’s name are represented as a symbol of an element. For example, sulfur is represented as symbol “S” and calcium is represented as “Ca”. But few elements have symbols that have no relationship with their names. For example, potassium is represented by symbol “K” and sodium is represented as “Na”. For such cases, origin of the elements is used.
- Potassium- K- Latin name Kalium –means alkali
- Sodium- Na- Latin name for sodium carbonate- Natrium

- Visit this website (http://openstaxcollege.org/l/ptable) to view the periodic table. In the periodic table of the elements, elements in a single column have the same number of electrons that can participate in a chemical reaction. These electrons are known as valence electrons. For example, the elements in the first column all have a single valence electron—an electron that can be donated in a chemical reaction with another atom.

- Of the organic molecules listed below, which group has the greatest variety of three-dimensional shapes? fatty acids DNA phospholipids carbohydrates proteinsarrow_forwardThe triple point of an element is at 75 torr and 125°C. This means that liquid is more dense than solid cannot exist at 1 atmosphere pressure cannot have a vapor pressure less than 75 torr cannot exist above 125 degrees Celsius What is the electron geometry (or electron arrangement) around an atom in a molecule or ion which is surrounded by three lone pairs of electrons and two single bonds T-shaped see-saw trigonal planar trigonal bipyramidal linear A red blood cell placed in pure water will swell because water moves from a higer osmotic pressure to a lower osmotic pressure the osmotic pressure is greater in the cell than in the water the osmotic pressure is the same in the cell and the water the somotic pressure is greater in the water than in the cellarrow_forwardOxygen has 8 protons, 8 neutrons, and 8 electrons.
