1. Nonmetals tend to ___ electrons to form ions of ___ charge. A. lose, negative B. lose, positive C. gain, positive D. gain, negative Nonmetals : Nonmetalsare the chemical species that do not possess metallic characteristics. This i...
These elements tend to have a low boiling point, melting point, and density. They are also unable to conduct electricity due to the low energy gap between the valence bond and conduction band which allows the outermost electrons to be somehow delocalized. Answer and Explanation...
Nonmetals form anions because they tend to gain electrons. On the other hand, metals form cations because they give up electrons. Why do nonmetals typically form anions? Since nonmetals have five, six, or seven electrons in their valence shells, it takes less energy to gain the necessary el...

–Metals tend to have low ionization energies and form (+) ions. –Nonmetals have high electron affinities and tend to form (-) ions. –Compounds of metals and nonmetals tend to be ionic substances. –Compounds of nonmetals are molecular substances. ...
Texas, for instance, is being slowly destroyed by an invasive speciesin the form of feral hogs, which have even started showing up in urban areas to wreak havoc, proving that invasive species aren't only destructive to natural environments. Meanwhile, the most ecologically diverse state in the...
The melting point of an element is when it converts from solid form to a liquid. Metals, which are physically flexible elements that can conduct heat and electricity, tend to be solid at room temperature due to their relatively high melting points. Nonmetals, which are physically weak and po...

They tend to lose electrons very easily and form positively charged ions. This allows metals to form compounds with other elements very easily. Metals corrode easily. They are damaged by oxidation like rust or tarnish Almost all metal combine with oxygen to form metal oxide Metals like lead, ...
Why do nonmetals tend to form negative ions? Why do ionic bonds form between metals and nonmetals? How do metals form ionic compounds with nonmetals? Why do metals conduct electricity? Give an answer in terms of electrons. How are metals different from nonmetals? Do nonmetals gain or lose...
