What class of element includes all of the elements that are gases at room temperature?
All the members of the noble gases family (group 18 of the periodic table) are gases at room temperature.
Which element will condense when cooled at room temperature from 100 Celsius?
Hydrogen, helium, nitrogen, oxygen, fluorine, neon, chlorine, argon, bromine, krypton, xenon and radon are all gases at 100 deg C. Only Bromine will condense if cooled to room temperature.
Are halogens all gases?
Bromine (Br2) and Iodine (I2) are liquids at room temperature and pressure
Is Mercury a liquid or a gas or a solid?
Mercury is a metal element. It can be all 3 stats depending on the temperature. At room temperature it is a liquid.
What is the only metallic element that is not a solid at room temperature?
A) Fe b) Hg c) Pb d) Au
What class of element includes all of the elements that are gases at room temperature?
All the members of the noble gases family (group 18 of the periodic table) are gases at room temperature.
Is a element a gas at room temperature?
The only gaseous METAL element at room teperature is mercury. Lucky for us oxygen is also gaseous at room temperature.
What twelve gas elements form at room temperature?
All of the noble gases (group 18) are gases at room temperature. In addition, fluorine, chlorine, oxygen, nitrogen, and hydrogen are gases at room temperature.
Is it true that some metalloids are gases at room temperature?
No. All metalloids are solid at room temperature.
Are nitrogen hydrogen oxygen and carbon all gases at room temperature?
Carbon is a solid; oxygen, nitrogen and hydrogen are gases at room temperature.
Which elements are all gases at room temperature group 1a?
The noble gases
Where do you find elements that are gases at room temperature on the table?
Near the top right. The Periodic Trend for boiling point is increasing from top right to bottom left. (Note: lower the boiling point, the more likely the element is gas at room temperature.) Elements such as Nitrogen, Oxygen, Helium, and Neon are all gases at room temperature.
Which element does NOT exist as a diatomic gas at room temperature and atmospheric pressure?
All group 18 elements (the noble gases) exist as monatormic gases at room temperature and standard pressure. All other elements form diatomic gases, if they exist as gas under the specified conditions. Among the listed elements there is only one noble gas: Argon
What is xenon at room temperature?
Xenon is an inert gas. Like all the inert gases, it is a gas at room temperature.
Are some metalloids gases at room temerature?
No. All metalloids are solid at room temperature.
What haiogen is a liquid at room temperature?
None of them are Fluorine, Chlorine and Bromine are all gases at room temperature. Iodine and Astatine are both solid at room temperature.
Why non-metals gaseous at room temperature?
The atoms of non-metals are covalently bonded in a molecule. These molecules are joint by weak intermolecular forces of attraction which are easily overcame. Hence the boiling point is low and usually below room temperature so at room temperature, they are gaseous.
