Simple molecular or Giant Covalent? - The Student Room
H2-simple molecular H20-simple molecular (now NaCl is a giant structure (forms a huge lattice) but it's ionic). Can't think of any giant covalent but diamond and graphite. [look up: simple molecular, giant covalent, ionic and metallic structures. Some things also just exits as single atoms like noble gases (with vander waals forces between atoms)].
What the difference between simple molecules and giant structures
You should google for pictures of these substances and you will see why they are called giant structure; many atoms are linked together to form a lattice (instead of 2, 3, 4,... atoms for simple molecules). Giant covalent structures usually have higher boiling, melting point due to their strong, extensive bonding.
How do you know if something is simple molecular or giant …
2020年11月23日 · simple molecular substances as the name implies are made up of small molecules, they are mostly covalent in nature and will have low melting and boiling points, this means that they will be gases and liquids at room temperature or solids like …
Simple Molecular or Giant Covalent? - The Student Room
How do you go about determining the structure of lattices with just the molecular formula? Eg. SiO2, initially I thought it would be O=Si=O giving it a simple molecular lattice, however, I found that it's Si with 4 single bonds to Oxygen as opposed to 2 double bonds with oxygen and that confused me because I thought it would then be SiO4?
Help with two exam question F321 - The Student Room
2023年11月13日 · Simple molecular is covalent. So like CO2 is simple molecule the molecule floats around as simple molecules of CO2 gas. Whereas diamond or graphite or silicon dioxide is giant macromolecular. Still covalent bonding but each atom is bonded to another in a giant structure. Whereas simple molecular the only forces of interaction are intermolecular ...

2021年3月21日 · Bromine-simple molecular lattice structure or simple covalent lattice structure Melting point depends on the induced dipole dipole forces between the molecules. The forces are weak and so easily overcome the increased kinetic energy hence has a low melting point Bromine has no mobile ions or delocalised electrons so is fixed in position so ...
Simple molecular and giant lattice structures question
Giant lattice is the same as giant ionic isn't it? Ionic/lattice is with metals bonded to non-metals like NaCl. Covalent's between non-metals and non-metals. I think only Carbon and Silicon do giant molecular (for AS levels anyway), otherwise it will be simple molecular. Hope that's right!
Do simple molecular covalent substances dissolve in water, and …
Correct it is a simple molecular structure because it doesnt conduct electricity and low melting and boiling point. Why do you think it might not or will dissolve. well it all depends on the polarity of the molecule is there anymore information or you could talk about intermolecular force (although im not sure if you do this for GCSE. Hmm use ...
What is the difference between a Giant Ionic Structure & Giant …
The word lattice just refers to the regular arrangement of ions in the structure... Simple covalent = discrete (small) molecules not formally attached to one another. Giant covalent = all the atoms in the structure bonded by formal covalent bonds. Effectively the entire structure is one molecule. Metallic bonding = bonding found in a metal. A ...
Chemistry AQA C2, difference between giant covalent, giant ionic …
This is a simple covalent molecule, as it is only small. Giant Covalent Lattice The bonding happens in the exact same way as oxygen, but this time let's look at carbon. Carbon has four electrons in its outer shell so wants to share an electron with four other carbon atoms to make a full shell of 8 electrons.
