What terms describe a substance that has a low melting point and poor electrical conductivity?
covalent and molecular
Do elements that have high electric conductivity also have high thermal conductivity?
Not necessarily. While there is some correlation between electrical and thermal conductivity in metals, there are exceptions. For example, diamond is a good thermal insulator despite being a good electrical insulator. Additionally, materials like ceramics can have low electrical conductivity but high thermal conductivity.
What is titanium chemical bonding?
Titanium chemical bonding primarily involves metallic bonding, where titanium atoms share a "sea" of delocalized electrons, allowing for conductivity and malleability. Additionally, titanium can form covalent bonds with nonmetals, such as oxygen and nitrogen, resulting in titanium oxides and nitrides. These compounds exhibit different properties and are used in various applications, including aerospace and medical devices. Overall, titanium's unique bonding characteristics contribute to its strength, low density, and resistance to corrosion.
What are the typical physical properties of substances that have metallic ionic and covalent bonds?
Metallic: melting point @ 63, boiling point @ 760, properties: soft, silvery, solid, and conductor as a solid. Covalent: melting point @ -101, boiling point @ -34.6, properties: greenish yellow gas and not a good conductor.
What is a characteristic of a covalent solid?
A characteristic of a covalent solid is that it consists of atoms or molecules held together by covalent bonds. These solids typically have high melting and boiling points due to the strong bonds between the atoms or molecules. Covalent solids are typically hard and have low conductivity of electricity and heat.
Is metal low conductivity?
No, metals have high conductivity but has low resistivity.
If glass is covalently bonded are the electrons free to move and how is this related to the electrical conductivity of glass?
In glass, the electrons are not free to move due to the covalent bonds holding the atoms together. This lack of free-moving electrons leads to glass being an insulator with low electrical conductivity.
Is the flammibillity and conductivity high or low for tin?
its a high flammibillity and low conductivity
What are similarities between ionic covalent and metallic bonds?
They are certainly not covalent in the sense of having localised 2 electron pair bonds. They have features in common with both ionic and delocalised covalent bonds.One very simple model describes metals as positive ions in a sea of electrons and while this rationalises the electrical conductivity of metals it does not explain why the metals generally have high melting points.The force that holds the lattice together is not a simple electrostatic force as in an ideal ionic lattice. In most metals some of the bonding derives from some covalent bonding between metal atoms allied with delocalised bonds occupied by free electrons. These delocalised bonds can be thought of as having superficial resemblance to the delocalised bonds in graphite.Read more: How_are_metallic_bonds_and_ionic_bonds_similar
Atoms of metallic elements can form ionic bonds but they are not very good at forming covalent bonds. Why?
they have a great tendency to lose electrons
Does copper possess high or low thermal conductivity?
Copper has a high thermal conductivity, not low. This is a good generalization of any metal, although they vary in conductivity.
Why might metallic bonding be weak compared to ionic and convalent bonding?
Metallic bonding is weaker than ionic and covalent bonding because metallic bonds are formed between delocalized electrons and metal ions, which have relatively low electronegativity differences. In contrast, ionic bonds involve the transfer of electrons from one atom to another, leading to strong electrostatic attractions, while covalent bonds involve the sharing of electron pairs between atoms, resulting in the formation of strong directional bonds.
