i) The atomic nuer of calcium is 20. Its electronic configuration is 2,8,8,2. The valency of calcium is +2. Hence it is a metal belong to the group 2. ii) The radius of calcium is smaller than potassium because both elements lie in the third period of the periodic table. Potassium lies to the left of calcium in the period, and atomic size decreases, going left to right due to increase in the

General physical and chemical properties of chemical elements defines elements as non-metal. Every element in the periodic table can be termed either a metal or a nonmetal. (A few elements with intermediate properties are referred to as metalloids). Non-metals cannot be hammered or beaten into thin sheets without breaking. Non-metals break into pieces when hammered or stretched.
25/02/2020· The nonmetals or non-metals are a group of elements loed on the right side of the periodic table (except for hydrogen, which is on the top left). These elements are distinctive in that they typically have low melting and boiling points, don''t conduct heat or electricity very well, and tend to have high ionization energies and electronegativity values.
Ytterbium is a chemical element with the syol Yb and atomic nuer 70. It is the fourteenth and penultimate element in the lanthanide series, which is the basis of the relative stability of its +2 oxidation state.However, like the other lanthanides, its most common oxidation state is +3, as in its oxide, halides, and other compounds.In aqueous solution, like compounds of other late

If you are trying to learn to distinguish between metals and non-metals, a list and their uses is a good way to break them down and help memorize the difference between the two. The good news is that most elements are metals. A useful way to approach the study of elements is to distinguish whether they are metal or non-metal.
