Sodium is a metallic element that is a member of the alkali metals (Group 1A). It is a very reactive element that readily tends to lose its single valence electron by forming an ionic bond with nonmetals. Answer and Explanation: The answer is d. Cl. The reactivity of...
The reactivity of an element can be discerned by knowing which family it is in, the halogens and alkali metals are the most reactive elements. The Noble gases are generally chemically inert, though most of them can be made to react with fluorine, the most reactive of the elements. When...
CO2 fire extinguishers or “Type C” labeled fire extinguishers are most effective in extinguishing electrical fires. These extinguishers displace the oxygen in the air with non-conductive agents like carbon dioxide to prevent the spread of electrical fire. It is important to know the different types...
How many electrons do noble gases have in their outer most level? Which group of elements shares characteristics with both metals and nonmetals? Which group of elements shares characteristics with metals and nonmetals? What kind of group 1 atoms are the most reactive?
The aqueous polyurethane/urea dispersions are suitable for coating and impregnating woven and nonwoven textiles, leather, paper, wood, metals, ceramics, stone, concrete, bitumen, hard fibers, straw, glass, porcelain, plastics of a variety of different types, glass fibers for antistatic and crease...
What element is the most abundant halogen? Which element has the lowest atomic number? What is the chemical name for water? What do all group 2 elements have in common? Which of the first 20 elements in the periodic table are metal and which are non-metals? What is ...
Answer and Explanation:1 In the periodic table, the element with the lowest electronegativity (i.e. the most electropositive element) iscesium. In fact, cesium belongs to... Learn more about this topic: Electronegativity | Definition, Importance & Examples ...
Through the addition of acids internal salts may be precipitated, however, the compounds are not very stable to acids and the use of weak acids may even cause some decomposition. The compounds are for the most part yellow to brown in color. They are very stable even at elevated temperatures...
Reactive chemistry-Spacer-Hydrophilic polymer-Spacer-Reactive chemistry The spacer used in the formation of constructs of the type outlined above may be any organic moiety that is a non-reactive, chemically stable, chain, Such spacers include, by are not limited to the following: —(CH2)n— wh...
The cysteine residues are believed to bind metals such as zinc while the intervening amino acids protrude in a finger-like projection. The rpt-1 protein has the potential to form two alternative fingers (FIG. 3). Secondary structure algorithms (Hopp, T. and Woods, K., 1981, Proc. Natl. ...
