The main classifications of matter include the categories element and compound, either of which may also be called a substance (which is a less specific term), and mixture, of which there are also many sub-categories.Definition of a (Chemical) Mixture:...
When calculating electronegativity of a compound, do you subtract all the electronegativity? For example, BeCl_2, is it Be-CL or Be-Cl-Cl? Which has a larger ionic radius: Ca(2+) or Ga(3+)? Rank the following ionic compounds in order of increasing melting points: CaO, KF,...
TheIMC is the abbreviation of Inter-Metallic Compoundin the electronic manufacturing industry. The IMC usually grows between the solder alloy and Cu or Ni substrate for thePrinted Circuit Board Assembly (PCBA). The IMC is neither a pure metal element nor alloy (Some expert think IMC is a kind...
What metallic element is found in limestone? What do all sulfide minerals have in common? What is the chemical formula for calcium bicarbonate? What is calcium bicarbonate found in? Which mineral among the following does not have a metallic luster? a. Pyrite b. Galena c. Graphite d. Dolomite...
Superconductor is an element, inter-metallic alloy, or a compound that conducts electricity without resistance below a certain temperature.Once set in motion, electrical current will flow forever in a closed loop of a superconducting material.
The net electrical charge of an ionic compound is zero. The unequal number of ions in a compound introduces the electric charge. The number of... Learn more about this topic: Ionic Compound | Formation, Properties & Examples from Chapter 5/ Lesson 3 ...
Compound that consists of at least two metallic elements which combines to give a new phase of same properties, composition and crystal structure of parent metallic elements is called intermetallic compound. Thus, from the given Cu-Zn phase diagram, the intermetallic compounds present are . Is Ceme...

Compound Exhibits properties different from its constituent elements. Sodium chloride is edible and crystalline, unlike either of its gaseous or metallic elements. 5 Alloy A substance made by melting two or more elements together, at least one of them a metal. Brass is an alloy of copper and ...
Metal hydrides are metals which have been bonded to hydrogen to form a new compound. Any hydrogen compound that is bonded to anothermetal elementcan effectively be called a metal hydride. Generally, the bond is covalent in nature, but some hydrides are formed from ionic bonds. The hydrogen has...
