Sulphur is a non-metal because it is consistent with three physical properties listed for non-metals. It isa poor conductor of heat and electricity, because electrons are not free to move. Can sodium conduct electricity? Solid sodium is good conductors of electricityas in sodium there is no ba...
What chemical bond forms when given different atoms: (1) bromine and hydrogen and (2) ammonia and calcium fluoride? Explain how you arrived at the answers. Why are metals good conductors, both of heat and electricity? Why do hot molecules move faster than cold molecules? In co2 laser, the...
For a substance to conduct electricity, it needs charged particles that are free to flow when a voltage (potential difference) is applied. The charged particles are usually electrons, but free ions can also conduct electricity...
Why do metals conduct electricity? Give an answer in terms of electrons. Why can transition metals form bonds with more than one ion? Why do delocalized electrons allow metals to conduct heat and electricity? Why is water tetrahedral? Why do ionization energy and electronegativity have the same ...
