Hydrogen is a part of the reactivity series of metals because like metals it also loses electrons to form a positive ion. To learn more about this concept and other related concepts, such as the electrochemical series, register with BYJU’S and download the mobile application on your smartphone...
are very likely to form ionic compounds after reacting with nonmetals like oxygen, fluorine, and sulfur that have high electronegativities. This results in a melt and boiling point higher than the norm because of the strong ionic bonds which exist between the smaller ions and what is often an...
positive bacteria, including pathogenic and drug-resistant ones, has been shown for several distinct transient metal and metal oxide NPs. Therefore, NPs may be used in biomedicine to treat periodontal problems and in nanotechnology to inhibit the development of microorganisms. Instead of using harmful...
Metals tend to form cations, while nonmetals tend to form anions. In the ionic bonding, the metal element always loses electrons and becomes a positive ion. True False Atoms form ions by losing or gaining electrons. True or false? True or false? Alkali metals tend to fo...
Among the metals Cr, Fe, Al, Ca, which has a greater tendency to form a metal oxide? Metals: Metals are the elements that can be found on the left side of the periodic table. The metals are separated from the nonmetals by the metalloids. The metals usually lose el...
