Is krypton a solid liquid or gas at -10 degees centigrade?
Krypton can be a solid, a liquid or gas depending on temperature and pressure. In solid form, it is a white crystalline material. You might recall that krypton is a noble or inert gas, and it boils at about −157 °C, and melts at about -153 °C. We don't see solid krypton anywhere but in the laboratory.
Diatomic molecules at room temperature?
Hydrogen, Nitrogen, Oxygen, Chlorine and Fluorine are diatomic gases. Bromine is a diatomic liquid. Iodine is a diatomic solid. (at room temperature)
Many elements found in nature exist as?
The chemical substances found in the atmosphere exist as gases.
Giant organic molecule made of small molecules linked together?
No, it is one molecule.However some large organic molecules (i.e. polymers) are formed from small organic molecules (i.e. monomers) that bond together into long chains, forming one new large molecule. The small molecules no longer exist as individual molecules after bonding into the large molecule.
Which molecules are compounds?
Molecules are the combination of two or more atoms which may exist free in gaseous form or in solutions, the ionic compounds are not the molecular compounds because their one unit can not exists freely but as the crystal lattice.
What do surfactant allow to exist?
Surfactant molecules allow many things to exist. This would include alveoli in the lungs, and particles of colloidal dimensions, such as micelle.
Why these gases argon krypton exist as monoatomic molecules?
Argon and krypton are noble gases, which have full outer electron shells and exist as monoatomic molecules because they are chemically stable and do not form bonds with other atoms easily. This stability is due to their electron configuration, which makes them content with existing as individual atoms rather than forming bonds with other atoms to complete their electron shells.
Which molecules contain the fewest covalent bonds?
Noble gases such as helium, neon, argon, krypton, xenon, and radon contain the fewest covalent bonds because they exist as monatomic molecules, meaning they exist as single atoms rather than bonded pairs of atoms.
Why doesn't krypton exist as diatomic molecules?
Krypton does not exist as diatomic molecules because it is a noble gas with a full valence shell of electrons, making it stable in its monatomic form. Unlike other elements that form diatomic molecules to achieve a stable electron configuration, krypton does not need to share electrons with another atom to reach a stable state.
How many atoms are in a krypton molecule?
Krypton is in Group 8 of the Periodic table, along with other Noble Gases such as Helium and Neon. Group 8 are known as the Noble Gases as they have a full outer shell of electrons, and don't need to bond to other atoms to full up their electrons, so they exist as single gaseous atoms. So, how many atoms are there in a Krypton molecule? One (it's technically not a molecule, but an atom, you don't get Krypton molecules!)
Can atoms of krypton exist independently?
Yes: Atoms of krypton almost always do exist independently of chemical bonding to any other atoms.
What properties of water allow it to exist as a liquid in oceans and rivers?
Its molecules are in constant motion, allowing for evaporation and condensation.
Which element exists as monatomic molecules as stp?
The noble gases always exist in monatomic form: Helium, Neon, Argon, Krypton, Xenon, and Radon.
How is krypton comercially valuable?
It doesn't really exist si it's not.
What elements do not naturally occur as a diatomic molecules?
Some elements do not naturally occur as diatomic molecules, such as helium, neon, argon, krypton, and xenon. These elements exist as monatomic gases because they are stable in their single atom form due to having a full valence electron shell.
When Salt dissolves in water what forces or attractions exist to attract them together?
When salt dissolves in water, there are mainly two types of attractions present: ionic bonding and hydrogen bonding. The positively charged sodium ions (Na+) are attracted to the negative oxygen atoms in water molecules due to ionic bonding. Meanwhile, the negatively charged chloride ions (Cl-) are attracted to the positive hydrogen atoms in water molecules through hydrogen bonding. These attractions help break apart the salt crystal and allow it to dissolve in water.
Does oxygen exist as atoms or molecules?
molecules
