sodium has weak metallic bonding in it. delocalised electrons are not located over a single atom but over a number of atoms. the weak bonding results in the softness of the metal. test your knowledge on sodium q 5 put your understanding of this concept to test by answering a few mcqs. ...
What are bromine's melting and boiling points? What is the melting point of graphene? Does stereochemistry affect melting point? What is the melting point of mercury? What is the melting point of helium? What is the melting point of californium in Fahrenheit?
the temperature coefficient of resistance is small, and it has good comprehensive mechanical properties. Therefore, as a non-ferrous metal, tungsten has very high strength and hardness. Due to this characteristic, tungsten carbide with high hardness and strong wear resistance is widely used in cuttin...
The bulk properties of astatine are not known with certainty. Many of them have been estimated based on the element's position on the periodic table as a heavier analog of iodine, and a member of the halogens (the group of elements including fluorine, chlorine, bromine, and iodine). ...
Its non-metallic form is less reactive but easily dissolves when heated with strong oxidizing acids and alkalis. Arsenic is a steel-gray, brittle solid with low thermal and electrical conductivity. There are some forms of elemental arsenic are metal-like and is best classified as a non-metal....
Question 3: Write a short note on the chemical properties of selenium. Answer: Selenium is a fairly reactive element. Selenium easily combines with hydrogen, fluorine, chlorine, and bromine. It reacts with nitric and sulfuric acids. Selenium also easily combines with a number of metals to form...
