Question

question 9 of 10
how is the name of each element in the periodic table represented?
a. letters are given to represent each element based on when it was discovered.
b. letters are assigned to each element by the scientist who discovered it.
c. one or two letters are used to represent the name of each element.
d. the first two letters of the elements name are used for the table.

Explanation:

In the periodic table, elements are represented by one or two - letter symbols. For example, hydrogen is represented as H (one - letter symbol) and oxygen as O (one - letter symbol), while elements like calcium are represented as Ca (two - letter symbol). The symbols are not based on the discovery time (option A is wrong), not assigned solely by the discovering scientist (option B is wrong as there are international naming conventions), and not always the first two letters of the element's name (e.g., tungsten is W from its Latin name Wolfram).

Answer:

C. One or two letters are used to represent the name of each element.
