Hydron, tritium, deuterium
Salt is an ionic compound consisting of a metal and a non metal.
Neon is a noble gas and thus non-metallic.
Diorite is not an element it is a rock type made up of several minerals. Therefore the term metallic or non-metallic can not be applied to it.
The number of electrons to be gained or lost is what differientiates metallic and non-metallic elements on the periodic table at a subatomic level.
Chromite is non - metallic
Salt is an ionic compound consisting of a metal and a non metal.
Non-metallic
It is a mixture - partially metallic and partially non-metallic
it must be a compound of a polyatomic cation (i think ammonium might be the only one) and any polyatomic anion that contains no metals (sulfate, chlorate, carbonate, etc). Some examples would be (NH4)2SO4, (NH4)2CO3, etc.
Sodium and magnesium are both ionic elements. Sodium forms a +1 cation, and magnesium forms a +2 cation when they lose electrons, resulting in the formation of ionic compounds when they react with non-metallic elements.
Neon is a noble gas and thus non-metallic.
Nitrogen is a non-metal.
The two main types of luster are metallic and non-metallic. Metallic luster refers to the shine of metals, while non-metallic luster includes categories like vitreous (glassy), pearly, greasy, and earthy.
A sharpened pencil lead is non-metallic. It is typically made of graphite, which is a non-metallic element.
Halite is a non-metallic mineral. It has a glassy or vitreous luster and typically appears transparent or translucent.
The metal become a cation.
fossils are not metallic minerals. marbles are non metallic minerals.
