The elements in group 18 _____.

are highly reactive
are gases at room temperature
usually do not react with other elements

are nonmetals

Answer 1

are gases at room temperature

usually do not react with other elements

are in a group called the noble gases

are nonmetals

Step-by-step explanation:

The elements in group 18 or group O are the inert elements. They have completely outermost shell and are not reactive. Every atom reacts with another in order to be like the noble gases.

• All of the elements here are gaseous.
• They do not readily react with other elements.
• They are called noble gases, inert gases, or group O elements.

It should be noted that group 17 elements are very reactive compared to the group O elements.
