The reason why the sodium, magnesium , aluminium and silicon are able to conduct electricity( presence of flowing of electrons) where as the the rest of element found in period 3 such as phosphorus, sulphur , clorine and argon( The presence of individual molecules prevents any possibility of electrons flowing) are not able able to conduct the electricity due to the concept of electron flowingIm doubt of this because i don''t fully understand the concept of electron flowing can anyone explain this for me? and one more thng is that what does it trying to tell us with the meaning of simple molecules?( such as phosphorus, sulphur.) if so, what does the magnesium, sodium belongs to? do we call them giant molecules? i really need help with this peopleand also the covalent bond and metallic bond.what is the different from them since all the elements are actually formed with sharing of neigbouring valence electrons? thanks!
don't shut it off, let the thermostat cycle the compressor and keep the fan running to circulate the air.
These symptoms are related directly to poor room insulationInsulate your ceiling space, and install a whirlybird to drop some of the heat in the attic.
