A substance is present in the gaseous state at room temperature. Which of the following best explains the probable position of t
he substance in the periodic table? It is between groups 1 to 12 because it is a metal.
It is between groups 13 to 18 because it is a metal.
It is between groups 1 to 12 because it is a non-metal.
It is between groups 13 to 18 because it is a non-metal.
<u>Answer:</u> The correct answer is it is between groups 13 to 18 because it is a non-metal.
<u>Explanation:</u>
The elements in the periodic table is classified as metals and non-metals.
Metals are the elements which loose electrons. They are present from group 1 to group 12 of the periodic table. They are generally solid at room temperatures. For Example: Sodium, Calcium etc...
Non-metals are the elements which gain electrons. They are present from group 13 to group 18 of the periodic table. They are generally gases at room temperatures. For Example: Fluorine, Oxygen etc..
Hence, the correct answer is it is between groups 13 to 18 because it is a non-metal.
