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
Calcium is a chemical element. Its syol on the periodic table (a list of all the elements) is Ca. Its atomic nuer is 20. (The atomic nuer says where Calcium sits in the periodic table.) It has 20 protons and 20 electrons (if is an atom, see ion). The most common isotopes are Ca-40 and Ca-44. Its mass nuer is about 40.08. Calcium is

Metal, Nonmetal, or Metalloid? Lab Background Elements have unique physical and chemical properties, which make them useful for specific purposes in our everyday world. All known elements can be classified as metals, nonmetals, or metalloids according to
The metal loses one or more electrons to become a ion, and the nonmetal gains one or more electrons to form an anion. The resulting substance is called a binary ionic compound. Binary ionic compounds contain a positive ion (ion), which is always written first in …
Metal is hard to pull apart (it has a high tensile strength) or smash (it has a high compressive strength). If you push on a long, thin piece of metal, it will bend, not break (it is elastic ). Except for cesium, copper, and gold, metals have a neutral, silvery color.
