How does the arrangement of the outer electrons in an atom determine how the atom bonds to others and forms materials?
Atoms react to attain completely filled outermost orbit.they can form ions,lose,gain or share electrons...if it requires less electron sharing then it will form single bond. Eg:H+H->H2 They will share one electrons. Oxygen requires two electrons for complete outer shell so it will share two electrons with other oxygen atom.thus they will have 4electrons in total.

What force determines chemical properties?
The arrangement of electrons in atoms determines their chemical properties. Specifically, the number of electrons in an atom's outermost energy level (valence electrons) and how easily those electrons can be gained, lost, or shared with other atoms dictate the chemical behavior of an element.
Why are some materials more conductive than others?
Materials with more free electrons are more conductive because these electrons can move freely in response to an electric field. In contrast, materials with fewer free electrons or tightly bound electrons impede the flow of electric current, making them less conductive. Additionally, factors such as crystal structure, impurities, and temperature can also influence a material's conductivity.
In a covalently bonded molecule the number of electrons that an atom shares with others is usually equal to the number of electrons?
In a covalently bonded molecule, the number of electrons that an atom shares with others is typically equal to the number of electrons needed to achieve a stable octet (or duet for hydrogen). This sharing allows each atom to satisfy the octet rule, resulting in a more stable molecular structure.
How do the valence electrons tell about the reactions of different elements?
Not sure if I understand your question correctly, but some elements are more electronegative than others, so they draw in electrons better than others. For example, in NaCl, chlorine (Cl) is much more electronegative than sodium (Na) so it simply takes the sodium's extra valence electron.
Which of the following would not have the same number of valence electrons as the others boron aluminum gallium selenium?
Selenium would not have the same number of valence electrons as the others. Boron, aluminum, and gallium all have 3 valence electrons, while selenium has 6 valence electrons.
Why do some materials conduct light and others do not?
Materials conduct light when they allow it to pass through without absorption or scattering, such as in transparent materials like glass or water. In contrast, materials that do not conduct light either absorb or reflect it, such as in opaque materials like wood or metal. The electronic structure and molecular arrangement of a material determine its transparency to light.
Do some materials hold onto electrons more tightly than others when charging by rubbing to occur?
Yes, some materials hold onto electrons more tightly than others. This property is known as electron affinity, and materials with higher electron affinities tend to hold onto electrons more strongly when charged by rubbing. Materials like rubber or wool have higher electron affinities compared to materials like silk or glass.

Why are some materials attracted to magnets and others not?
Ferro magnetic materials (those attracted to magnets) have a special arrangement of their electrons which makes them susceptible to magnetic fields. Materials without this special electron structure are not affected my magnets or electric fields in the same way.
What makes some liquids have a greater surface tension than others?
The surface tension is primarily due to the arrangement of electrons of the molecules that comprise the liquid.
Why are some materials stronger than others?
Some materials are stronger than others due to their atomic structure and bonding. Materials with strong atomic bonds, such as metals, tend to be stronger than materials with weaker bonds, such as plastics. Additionally, the arrangement of atoms and the presence of defects in the material can also affect its strength.
Why do some materials conduct and others don't?
Materials conduct electricity based on their atomic structure and the availability of free electrons. Conductors, like metals, have a high density of free electrons that can move easily through the material, allowing electric current to flow. In contrast, insulators, such as rubber or glass, have tightly bound electrons that do not move freely, preventing electrical conduction. The differences in electron mobility and bonding determine a material's ability to conduct electricity.

Materials with more free electrons are more conductive because these electrons can move freely in response to an electric field. In contrast, materials with fewer free electrons or tightly bound electrons impede the flow of electric current, making them less conductive.

Why do some materials have more resistance than others?
Materials with more resistance have a higher resistivity, which is a measure of how strongly a material impedes the flow of electric current. Factors such as the material's atomic structure, temperature, and impurities can affect its resistivity. Materials like metals tend to have low resistivity due to their abundance of free electrons, while insulating materials have higher resistivity as they inhibit the movement of electrons.
Why do certain materials carry a current while others cannot?
Materials conduct electricity when their electrons are able to move freely. In conductors like metals, electrons are loosely bound and can move easily with the application of a voltage, allowing electric current to flow. Insulators, on the other hand, have tightly bound electrons that do not move easily, making them poor conductors of electricity.
Are all metals magnetic materials?
Most metals are NOT magnetic; Iron, Steel (Contains Iron in it), Nickel and Cobalt are the only magnetic materials. Nearly ALL metals are electrical conductors, however, so don't get it mixed up. Last edited (re-written) by 09pwang.
