<h2>Answer:</h2>
<u>The right option is</u><u> (C) intermediate conductivity and a high melting point</u>
<h2>Explanation:</h2>
Metalloids usually look like metals but behave largely like nonmetals. Metalloids are shiny, brittle solids with intermediate good electrical conductivity. Their properties lie between metals and non metals. All metalloids exist as solids at room temperature and they have very high melting points. The physical properties of metalloids are more likely to be metallic, but their chemical properties tend to be non-metallic
A mole is equivalent to 6.02 x 10^23 molecules at STP. Use a conversion factor like the following.

Isoelectronic species are ions or elements that have equal number of electrons. From the root word, electron of the word isoelectronic. On the other hand, isotructural species are compounds with the same structures.Hope this answers the question.
An excited state refers to an atom with electrons at a higher energy level. More than necessary and a ground state is when all atom's electrons are in their lowest orbital possible
