What is it that atoms of materials that conduct electricity best tend to be held together by?
Atoms of materials that conduct electricity best tend to be held together by metallic bonds. This is the attraction between positively charged nuclei in metal atoms and the delocalized electrons in the metal.
Does metal conduct heat readily?
Metal does indeed conduct heat readily. Metal also conducts electricity. The conductive properties of metal are due to the free electrons in metal atoms that allow for mobile charge.
A scientist conducted an experiment to determine how acids affect a newly discovered metal The scientist was careful to record the steps of her experiment as well as her observations and results?
Study Island Answer.... Report her results to the scientific community.
How are particles arranged in a solid metal?
like this ::::::::::::: ::::::::::::: ::::::::::::: though a little closer. It depends on the metal, but atoms in a pure solid are tightly-packed into a crystalline structure. The shape of the crystal is dependent upon the atom.
How does lubricating machinery-such as the chain on your bike reduce friction?
The surface tension between the metal on your chain pieces is high. The surface tension is low on lubricants like oil or graphite so putting them between moving surfaces provides a opposing surface for both materials that has a low friction.
What made the metal shiny again?
Metallic bonding is quite strong and gives rise to the metal cations(atoms) to be packed in a regularly shaped pattern. The closely packed rows or atoms organised in rows allows light to reflect on its surface. Thus, it is shiny
The shiny surface of metals have most to do with?
The looseness of electrons in metal atoms.
Why is metal conductive and how does its atomic structure contribute to its ability to conduct electricity?
Metal is conductive because its atomic structure allows for the movement of electrons. In metals, atoms are arranged in a regular pattern, with outer electrons that are free to move between atoms. This "sea of electrons" allows for the easy flow of electricity through the metal, making it a good conductor.
What happens to metal when it's heated?
When metal is heated, its atomic structure allows the atoms to vibrate more rapidly, causing the metal to expand. If heated to a high enough temperature, the metal can eventually melt and turn into a liquid. Additionally, heating can cause the metal to change color due to oxidation reactions on its surface.
Do constituents atom in the metal can move?
Yes, the constituents atoms in a metal can move. In metals, the atoms are arranged in a crystal lattice structure that allows them to move and slide past each other, giving metals their characteristic ability to be malleable and ductile.
When metal atoms combine chemically with atoms of other elements what do they usually do?
Metal atoms usually lose electrons to form positive ions when they combine chemically with atoms of other elements. This allows them to achieve a more stable electron configuration by attaining a full outer shell.
Corrosion involves atoms at the surface of a metal losing electrons and changing to metal ions state the name of this kind of reaction?
The corrosion of metals involves a redox reaction. In an oxidation-reduction or redox reaction, metals lose electrons to oxygen to form a ionic compound from the metal ions and an ion of the oxide.
When electromagnetic radiation strikes the surface of a metal electrons are ejected from the metal's surface what is the description?
This phenomenon is known as the photoelectric effect. When electromagnetic radiation, such as light, strikes a metal's surface, it can transfer energy to the electrons in the metal. If the energy of the incoming photons is sufficient to overcome the metal's work function, the electrons are ejected from the surface. This effect demonstrates the particle-like behavior of light and supports the concept of quantized energy levels in atoms.
What type of bond allows medal to be flattened and shaped?
Metallic bond allows metal atoms to be flattened and shaped because the electrons are delocalized and free to move throughout the metal lattice, allowing the metal to be easily deformed without breaking the bond.
When electroplating silver or iron what is oxidized?
In the electroplating process, during the oxidation reaction, silver atoms are oxidized to Ag+ ions for silver plating, and iron atoms are oxidized to Fe2+ ions for iron plating. This allows the metal ions to be deposited onto the object being plated.
Why can you see you're reflection in polished metal?
You can see your reflection in polished metal because the metal surface is very smooth and acts like a mirror, reflecting light in a way that allows you to see yourself. The smoothness of the surface allows light to bounce off and create a clear image, similar to how you see your reflection in a regular mirror.
Is a shiny plate of metal said to be a mirror?
Yes, a shiny plate of metal can be considered a mirror if its surface is smooth enough to reflect light clearly. Mirrors typically have a reflective surface that allows them to produce a clear image, and polished metal can achieve this quality. However, the effectiveness of the metal as a mirror depends on its finish and the quality of the surface.
