While going down in the group of non-metals (14, 15, 16 and 17) the electronegative character of non-metals decreases. Typical example is of group 15 elements. The elements nitrogen (2nd period) and phosphorus (3rd period) are non-metals and their oxides are acidic in nature. The element...
Non-metals also react with oxygen to make oxides. Oxides of non-metals are acidic in nature.Example: Sulphur reacts with oxygen when it is burnt. It forms sulphur dioxide.S + O2→ SO2When sulphur dioxide is dissolved in water, it forms sulphurous acid....
Explain why metal oxides tend to be basic if the oxidation number of the metal is low and acidic if the oxidation number of the metal is high. Explain why metals conduct electricity. Why is iron more reactive than copper? Why do metals tend to be malleable?
While research regarding the detrimental effects of cooking with aluminum is inconclusive, there are concerns over aluminum leaching into food when in contact with acidic foods (tomatoes, vinegar), though leaching is not a concern for aluminum-based cookware that is coated or treated (anodized). It...
Non-metals are natural elements which do not have metallic properties. Often, they are available in the solid or gaseous state. In this type of elements, bromine is an exception as it exists in liquid state. They are good insulators of electricity and heat, non-lustrous (iodine is an excep...
In general, current Mg-air batteries are primary batteries based on either alkaline or acidic aqueous electrolytes with relatively few studies37,51,53,93,94,97, 98, 99, 100 concerning the possibility of electrically rechargeable Mg-air batteries based on non-aqueous electrolytes due to difficulties...
More encouragingly, these graphene-based catalysts show favorable HER activity in a wide range of pH values, in contrast to traditional metallic and nanostructured MoS2 electrocatalysts, which are active under either acidic or basic conditions. To design high-performance electrocatalysts for HER, Jiao ...
Metal oxides have remained in the spotlight for researchers working in areas such as chemistry, physics, and polymer sciences. Metal oxides can inhibit the nanosized structural geometry exhibiting metallic, semiconductor, or insulating characteristics. These metal-based nanoparticles are exceptionally mobile...
Lanthanide intermediate alloys, also known as master alloys, have metal characteristics and are composed of mixed lanthanide metals or a single lanthanide metal and non-ferrous metals, such as aluminium, magnesium, copper, zinc, and titanium. The basic use of lanthanide intermediate alloys is as ad...
Prepared Ch-Mn3O4NPs are catalytic in nature in the acidic media (for experiment Sodium acetate buffer of pH 4.2 is used). It catalyzes oxidizing reaction to produce H2O2from glucose and·OH from H2O2along with oxidizing another substrate in the system, similarly as it happens for the GOD-...
