What substances are a simple molecular a giant covalent or ionic or have another type of structure?
Substances can be classified based on their bonding and structure. Simple molecular substances, like water (H₂O) and carbon dioxide (CO₂), consist of small molecules held together by weak intermolecular forces. Giant covalent structures, such as diamond and graphite, feature a vast network of covalent bonds, resulting in high melting points and hardness. Ionic substances, like sodium chloride (NaCl), consist of positively and negatively charged ions held together by strong electrostatic forces in a lattice structure.

How can different substances be compared?
Different substances can be compared based on their physical and chemical properties, such as density, melting and boiling points, solubility, and reactivity. Additionally, their molecular structure, composition, and behavior under various conditions (like temperature and pressure) provide insight into their differences and similarities. Comparative studies often involve quantitative measurements or qualitative observations to assess how substances interact with one another or their environments.
Is the ability to combine with another substance physical?
Yes, the ability to combine with another substance is a physical property that depends on the chemical composition and structure of the substances involved. The physical properties of the substances, such as molecular size, polarity, and intermolecular forces, determine how easily they can combine with each other.
How does molecular structure make one sugar sweeter than another?
The molecular structure of sugars determines their sweetness. Sugars with simpler structures like glucose and fructose are sweeter than sugars with more complex structures. The ability of a sugar molecule to fit into sweet taste receptors on the tongue contributes to its sweetness level.
How to classify substances according to their chemical bonds?
Substances can be classified based on their chemical bonds as covalent, ionic, or metallic. Covalent bonds are formed through sharing of electrons between atoms, ionic bonds are formed through transfer of electrons from one atom to another, and metallic bonds involve a shared pool of electrons among all atoms in a metal.
Substances that are chemically bound together are?
Some substances that are covalently bonded are any alkanes, alkenes, and alkynes. Water is another substance that is covalently bonded, as is sugar. Carbon compounds generally contain covalent bonds.
What are the properties of simple covalent substances such as chlorine oxygen and water?
The properties of simple covalent substances such as chlorine, oxygen and water are that it has low melting and boiling points. This is because the weak intermolecular forces break down easily. Secondly, another property is the simple covalent substances are non-conductive therefore the substances with a simple molecular structure do not conduct electricity. This is because they do not have any free electrons or an overall electric charge.
Which formula represents a substance that contains covalent bonds?
A substance that contains covalent bonds can be represented by a molecular formula, such as H2O for water or CO2 for carbon dioxide. These formulas show the types and numbers of atoms in a molecule held together by shared pairs of electrons in covalent bonds.
What covalent structure has a layer that moves over another?
Graphite.
Why carbon monooxide is a molecular compound?
Carbon monoxide is a molecular compound because carbon and oxygen form a covalent bond with one another.
What kind of scientist studies hydrogen and oxygen and another basic substances?
A chemist would study hydrogen, oxygen, and other basic substances as part of their work in the field of chemistry. Chemists focus on the composition, structure, properties, and reactions of substances at the molecular and atomic levels.
Is CF2Cl2 a molecular or ionic compound?
No, CF2Cl2 is covalent as the the three elements in it (Carbon, Fluorine, and Chlorine) are all nonmetals. Nonmetals form covalent bonds with one another.
Is sulfur dioxide a molecular compound?
Yes. Sulfur and oxygen are both nonmetals. Nonmetals form covalent bonds with one another, and are therefore molecular compounds.
What type of structure does fluorine have?
Fluorine has a simple molecular structure where each fluorine atom is covalently bonded to another fluorine atom to form a diatomic molecule F2. Each fluorine atom contributes one electron to form a single covalent bond between the two atoms.
How is the term molecular properly defined?
Molecular is defined as something of, related to, or consisting of molecules. Another definition of molecular is something of or related to a basic form or structure.
What is 'like dissolves like'?
The chemistry principal of "like dissolves like," explains that polar substances will dissolve in each other. Similarly, a covalent will dissolve another covalent.
Molecular bonds have what kind of bonds?
"Bonds" do not "have" bonds, because they are bonds themselves. The questioner may have meant to ask, "Molecular compounds have what type of bonds?", and the answer to that question is "covalent bonds".
Is iodine has a giant covalent structure?
No, iodine does not have a giant covalent structure. Iodine exists as diatomic molecules (I2) held together by weak van der Waals forces. Each iodine atom forms covalent bonds with one another within the I2 molecule.
