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.
Why are halogen poor conductor of both heat and electricity?
Halogens have 7 valence electrons (electrons in their last shell), this means that they require one more electron to become stable (Octet rule). Electricity and heat are conducted when atoms share electrons by bonding (ionic, covalent, and metallic). Metals are good conductors of heat and electricity because they have free moving electrons. Halogens tend to keep their electrons since they have a -1 charge. As one electron is gained for the halogen atoms (diatomic) become stable, it conducts electricity and heat. However, the conduction of heat and electricity is poor because it barely reacts (only one electron reacts). Compare this to any other element which has a higher charge as (+2, -2, +3, -3, etc.), then the other element will conduct heat and electricity better than a halogen. This is because more electrons are shared / reacted, more conduction of electricity and heat (Heat and electricity are sometimes the result of electron movement, or that electrons carry heat and electricity). Note: A special case is an alkali metal which also has one electron to donate, therefore it has a +1 charge. Alkali metals still conduct electricity and heat because they have free moving electrons (delocalized in a sea of electrons moving freely even without reacting). Basically, metals have their own structure where all the electrons move around freely conducting electricity (therefore its an amazing conductor).
Why does passing a current through a wire create a magnet?
That is, basically, the way ALL magnets are created - by moving electric charges. In the case of a permanent magnet, it is mainly the electrons orbiting their atoms that produce this effect. As to the "why", the Special Theory of Relativity provides an answer, but it is fairly complicated. The summary paragraph on Wikipedia (article "Magnetism") says: "As a consequence of Einstein's theory of special relativity, electricity and magnetism are fundamentally interlinked. Both magnetism lacking electricity, and electricity without magnetism, are inconsistent with special relativity, due to such effects as length contraction, time dilation, and the fact that the magnetic force is velocity-dependent. However, when both electricity and magnetism are taken into account, the resulting theory (electromagnetism) is fully consistent with special relativity. ..." The Wikipedia article "Classical electromagnetism and special relativity" provides a more detailed explanation about the relationship between electricity and magnetism, according to the Special Theory of Relativity - but the math is a bit too complicated for my liking.
How can you turn solar energy into electricity?
In two ways.Photovoltaic (PV) cells and panels convert energy from sunlight into a flow of electrons (electricity).Solar ovens and solar farms use mirrors to focus the sun's rays onto a central point. Concentrated Solar Power (CSP) stations typically heat a central tank of a medium (like molten salt) to more than 600° Celsius. This heat is used through steam to run electricity turbines, including overnight, as the heat is retained for many hours.PV Cells:Photons in sunlight hit the solar panel and are absorbed by semiconducting materials, such as silicon.Electrons (negatively charged) are knocked loose from their atoms, allowing them to flow through the material to produce electricity. Due to the special composition of solar cells, the electrons are only allowed to move in a single direction.The earth receives 170 pet watts of solar radiation. 30% is reflected into space and the rest is absorbed by the earth. Most of the solar radiation falls in the visible to near infrared region of electromagnetic spectrum with a small amount in the ultraviolet region.
What do nuclear weapons contain?
Everything an ordinary bomb or warhead would contain plus special nuclear materials. The important thing though is the arrangement of the various materials.
How is light absorbed and made into electricity?
light is absorbed by special cells known as photoelectric cells...... these cells are made uf certain materials that release electrons upon absorbing energy in the form of light...
Why some materials are magnets and some are not magnet?
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 do electrons do to the nucleus?
Electrons orbits around the nucleus, which have neutrons and protons. When there is an imbalance of protons and electrons, it creates a static electricity. What I am trying to say is, nothing really special happens.
Are there any non metal materials that conduct electricity?
I think there is one. The thing that is in pencils not lead it has a special name look it up.
What is it that metals have that allow them to form their special metallic bonds?
Metal atoms are bonded each other with metallic bonds. A special feature in metallic bonds is the existence of 'pool of electrons'. It is responsible for the conductivity of electricity and heat in metals.

How does copper and zinc conduct electricity?
All metals (copper included) form crystals that have the valance electrons in a free floating sea. They are not affiliate with any single atom and can move (fairly) freely between associated atoms. Shoving a charge in at one end of a wire therefore allows all the electrons to 'shove-over' and kick one out the other end.

Is all electricity made the same way?
No. Mostly electricity is made by induction in a coil of wire by moving a magnetic field across it, such as in generators at power stations and alternators in cars. Electricity can also be made by chemical action on plates of dissimilar metal, such as in batteries. Also electricity can be made by light photons, displacing electrons in special material, such as in photovoltaic cells Bending crystals can also produce electricity such as in piezo electric effect, used in lighters.
