Question

why does silicon exists as a solid at room temperature while non-metals like chlorine exists as a gas?

Answer 1

Answer:

Metals have the potential to contain a lot of material, are malleable and ductile, and can carry heat and electricity. Non-metals lack the properties of metals, such as shine, hardness, fusibility, etc.

Explanation:

At room temperature, chlorine gas is a gas due to its high volatility and little covalent bonding, whereas silicon is solid with extensive covalent bonding, making it essentially a solid.

A covalent bond is a chemical bond between atoms that involves the exchange of electron pairs.

Covalent bonding is the stable balance of the attractive and repulsive forces between atoms when they share electrons, as opposed to shared pairs, or bonding pairs, which are the stable balance of the opposing forces.

Each atom in many molecules can attain the equivalent of a full valence shell thanks to the sharing of electrons, leading to a stable electronic state. In organic chemistry, covalent bonds are far more common than ionic ones.

Hence, silicon exists as a solid at room temperature due to its high volatility while non-metals like chlorine exists as a gas due to higher covalent bonding.

Answer 2

Answer:

Silicon does now no longer shape double bonds with oxygen. CO2 is fueloline however SiO2 is stable due to the fact the SiO2 is in large molecular shape however the CO2 is straightforward molecular shape. Due of this cause CO2 is fueloline however SiO2 is stable

Explanation:

Carbon dioxide is a colourless fueloline with a density this is round 60% that of dry air. A carbon atom is covalently doubly connected to 2 oxygen atoms to shape carbon dioxide. It is observed as a hint fueloline withinside the Earth's atmosphere.

Silicon dioxide, frequently called silica, is a silicon oxide with the chemical system SiO₂ this is observed in nature as quartz and in plenty of residing creatures.

Because of what are called "van der Waals forces" or "London forces," every molecule in CO₂ (O=C=O) is drawn to neighbouring molecules. Van der Waals forces are a susceptible sort of intermolecular interplay that draws brief and brought about dipoles.

Carbon dioxide melts at barely over -56.6 tiers Celsius due to the fact Van der Waals forces can be damaged with minimum energy.
