Which element does not exist as atomic state?
Noble gases, such as neon, argon, krypton, xenon, and radon, typically exist as atomic states due to their full valence electron shells, making them chemically inert. However, elements like phosphorus can exist in various molecular forms, such as P4, rather than as individual atoms. Thus, while many elements can exist in atomic states, phosphorus is an example of an element that does not exist in that form under standard conditions.
Which gas is nonatomic at room temperature and pressure?
Except Nobel gases all other gases are molecular. The Nobel Gases, Family or Group 18 are atomic.
What has the author Lothar Frommhold written?
Lothar Frommhold has written: 'Collision-induced absorption in gases' -- subject(s): Absorption and adsorption, Gases, Infrared radiation, Molecular spectra 'Collision-induced Absorption in Gases (Cambridge Monographs on Atomic, Molecular and Chemical Physics)'
Why oxygen nitrogen exist in molecular state?
Oxygen and nitrogen are diatomic molecules, meaning they exist as molecules consisting of two atoms of the same element bonded together. Oxygen forms O2 molecules while nitrogen forms N2 molecules due to the stability achieved through electron sharing in the covalent bonds between the atoms. This molecular form allows them to exist in a gaseous state at room temperature and pressure.
Why noble gases do not exist as molecules?
They have completely filled valence electrons, hence are stable, chemically inert. So they exist as mono atomic species and not as molecules
Do noble gases have low densities?
Yes, noble gases have low densities because they are all gases at room temperature and pressure. These gases have low molecular weights and exist as single atoms rather than molecules, contributing to their low density properties.
What are the gases found in the thermosphere?
Oxygen-20%Nitrogen-80%Helium-1%
Which of the naturally occurring elements on earth exist as gases at room temperature?
At room temperature, the naturally occurring elements that exist as gases include hydrogen (H), nitrogen (N), oxygen (O), fluorine (F), neon (Ne), chlorine (Cl), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). These elements are typically found in the gaseous state due to their low molecular weights and the nature of their atomic structures. Most of these gases play crucial roles in various atmospheric and biological processes.
What is the percent of gases in the mesosphere?
The mesosphere is primarily composed of molecular nitrogen (N2) and atomic oxygen (O). These gases make up the vast majority of the mesosphere, with trace amounts of other gases such as carbon dioxide (CO2), ozone (O3), and water vapor (H2O).
Can a gas exist at -273K?
The lowest possible temperature is -273.15 C which equated to '0'K. Therefore, temperature -273K cannot exist. No -ve K temperatures exist.
What ionosphere gases make up this region?
The ionosphere is composed mostly of atomic oxygen, molecular oxygen, and nitrogen gases. These gases become ionized by solar radiation, creating charged particles that affect radio wave propagation and other communication signals in the Earth's atmosphere.
Amine exist as liquids or solid at room temperature?
Mostly true, though methylamine and ethylamine are both gases at room temperature.The dividing line between liquids and solids at room temperature of 1-aminoalkanes is about 1-aminododecane, which melts at 27-29 degrees Celsius.
