Which of the following does not form diatomic molecules?
Which of the following does not form diatomic molecules?
Argon
How do you know if a gas is monatomic or diatomic?
In a monatomic (mono-: one) gas, since it only has one molecule, the ways for it have energy will be less than a diatomic gas (di-: two) since a diatomic gas has more ways to have energy (Hence, diatomic gas has a 5/2 factor while a monatomic gas has a 3/2).
Why Sulphur does not exist as diatomic in nature?
Sulphur has a atomic number of 16. The first shell has 2 electrons, second shell has 8 electrons and valence shell has 6 electrons. It has a valency of 2, thus can form two bonds with other atoms. So, the covalent bonds break and Sulphur can not form a diatomic molecule at room temperature.
Why oxygen is gas and Sulphur is solid?
The intermolecular forces in oxygen are weak van der Waals forces, which causes it to exist as gas. On the other hand, sulphur does not form strong S=S double bonds hence exists as a puckered structure held together by strong covalent bonds and exists as a polyatomic molecule. So, it exists as a solid.
Why does S8 exist?
It is because of its size. S8 has puckered ring structure where each sulphur atom is bonded with two other atoms forming a ring. In S8 the bond angle between two bonds of one sulphur atom is relatively small and they can withstand because of larger size of sulphur atom which makes repulsion between them weaker.
Which form of Sulphur is paramagnetic?
In the vapor phase sulphur exists as S2 molecule and S2 molecule has two unpaired electrons in the antibonding 3p orbital and hence exhibits paramagnetism.
Is chlorine paramagnetic or diamagnetic?
Magnetic Type of the elements
| Hydrogen | Diamagnetic | Niobium |
|---|---|---|
| Chlorine | Diamagnetic | Lanthanum |
| Argon | Diamagnetic | Cerium |
| Potassium | Paramagnetic | Praseodymium |
| Calcium | Paramagnetic | Neodymium |
How do you draw an Aufbau diagram?
The following steps detail how to draw an Aufbau diagram:
- Determine the number of electrons that the atom has.
- Fill the s orbital in the first energy level (the 1s orbital) with the first two electrons.
- Fill the s orbital in the second energy level (the 2s orbital) with the second two electrons.
