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
