Dec 27, 2015· 1 Answer1. Active Oldest Votes. -1. The electronic configuration of Ca is 1 s X 2 2 s X 2 2 p X 6 3 s X 2 3 p X 6 4 s X 2. It has a total 4 Energy levels. The outermost energy level has 2 electrons called valance electrons. As, Calcium is metal and it can easy donate two electrons and becomes ion (Ca+2). Now, this ion is stable.
Non-metals are the elements in groups 14-16 of the periodic table. Non-metals are not able to conduct electricity or heat very well. As opposed to metals, non-metallic elements are very brittle, and cannot be rolled into wires or pounded into sheets. The non-metals exist in two of the three states of matter at room temperature: gases (such as

Selenium is a chemical element with the syol Se and atomic nuer 34. It is a nonmetal (more rarely considered a metalloid) with properties that are intermediate between the elements above and below in the periodic table, sulfur and tellurium, and also has similarities to arsenic.It rarely occurs in its elemental state or as pure ore compounds in the Earth''s crust.
over 14,500 citations and orders to metal/nonmetal operators related to workplace examinations, including 81 issued for fatal and non-fatal accidents. • If implemented, this nuer is expected to increase, along with Section 110 special investigations against company “agents.” 17
Calcium is also an Alkaline Earth Metal and is found in chalk, limestone, gypsum and anhydrite. Magnesium is the eighth most abundant element in the Earth''s crust, while calcium is the fifth. The metals of Group 2 are harder and denser than sodium and potassium, and have higher melting points.
Metal, Nonmetal, or Metalloid? Objective: Explore the physical and chemical properties of eight elements with the goal of classifying them as metals, nonmetals, or metalloids. Background: Physical Properties: – properties that can be observed without changing the identity of a substance
The most difficult to classify are the metal/non-metal mineral coinations. These minerals, which coine metals such as iron with the very non -metallic elements of carbon, nitrogen, phosphorous and silicon are quite unique and quite rare. They are . Organic, Inorganic, Metallic & Non-Metallic Minerals

Calcium metal in air, corroded. 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 ).
An ion (/ ˈ aɪ ɒ n,-ən /) is a particle, atom or molecule with a net electrical charge.. The charge of the electron is considered negative by convention. The negative charge of an ion is equal and opposite to charged proton(s) considered positive by convention. The net charge of an ion is non-zero due to its total nuer of electrons being unequal to its total nuer of protons.

Metalloids have properties of both metals and non-metals. Some of the metalloids, such as silicon and germanium, are useful in semi-conductors. This property makes metalloids useful in electronic components. Some allotropes of elements show more pronounced metal, metalloid or non-metal behaviour than others.
