Substances as we know them are not made up entirely of electrons. Electricity is composed of moving electrons, but it is not exactly a substance.
conductor
Heterogeneous
If an electric current doesn't pass easily through a substance, such a substance is said to be an INSULATOR.
Hydrogen Flouride
Heat moves easily through materials with delocalised electrons, that is electrons which are free to move through the substance. This happens in metals and graphite.
This mixture is called non homogeneous.
A substance that allows electrons to pass through easily is a transition metal. Transition metals organize forming a sea of delocalized electrons and metal cations, allowing electrons to pass through easily.
Yes they can be easily separated.
A substance that is good at reducing another atom
A conductor
compound. B. substance. C. heterogeneous. D. homogeneous.
yes all homogeneous are pure substance because all the part are the same throughout and they cannot be easily separated or broken down into simpler substance by physical means.
