Why are metals good conductors of electric current? a. They possess high concentrations of protons. b. They possess low concentrations of protons. c. They possess high concentrations of free electrons Explain why nuclei that contain more than 82 protons are radioactive. ...
Why are ionic solids poor conductors of electricity? Why do nonmetals tend to form negative ions? Why do elements lose electrons? Suggest how 'metallic bonding' explains the properties of metals. Why can transition metals form bonds with more than one ion? Explain a model for m...
Metals:Metals are considered opaque substances that have the property of high malleability as well conductivity. Metals are elements that can form cations very easily in order to form metallic bonds. Some examples of metals are sodium and magnesium....
Why are there no double bonds in BeCl2? Why does I_2 have a higher boiling point than F_2? Why does the boiling point decrease with a decrease in pressure? Why do some metals conduct heat better than others? What causes their difference in heat conductivity?
The heavier elements are those elements whose atomic number or the number of proton in their nucleus are greater than 92. However, the lighter element is those less than 92. Usually, the heavier elements are unstable because of high internal energy due to nuclear forces, consequently, the ...
