is calcium metal nonmetal or semimetal strength

Metallic bonding - Wikipedia

Metallic bonding is a type of chemical bonding that rises from the electrostatic attractive force between conduction electrons (in the form of an electron cloud of delocalized electrons) and positively charged metal ions. It may be described as the sharing of free electrons among a structure of positively charged ions ().Metallic bonding accounts for many physical properties of metals, such as

A metalloid or semimetal is a chemical element.Metalloids are elements that have the properties of both metal and non-metal elements.It might be shiny, but brittle. It might be dull, but conducts electricity. The most common semimetal is silicon.Silicon has electrical conductivity between metals and nonmetals. It is a semiconductor.

It is a metalloid (it has properties of a metal and a non-metal). It is a brittle and easily pulverized metalloid. Astatine may be a nonmetal or a metalloid. A third option is to include astatine both as a nonmetal and as a metalloid. As an alloy, this metalloid greatly increases lead''s hardness and mechanical strength.

The electrons in nonmetals are localized in covalent bonds, whereas in a metal, there is delocalization of the electrons throughout the solid. The noble gases are all monatomic, whereas the other nonmetal gases—hydrogen, nitrogen, oxygen, fluorine, and chlorine—normally exist as the diatomic molecules H 2, N 2, O 2, F 2, and Cl 2.

For this lab experiment, our new group, The Acids, tested sample elements A-G with the hopes in gaining enough knowledge to characterize each sample as a metal, a nonmetal, or a metalloid. To prepare for the simple, yet tedious procedure, we placed each of the seven elements on a piece of paper, and labeled them to prevent confusion.

This line has been called the amphoteric line, the metal-nonmetal line, the metalloid line, the semimetal line, or the staircase. It is also erroneously [citation needed] referred to as the Zintl border or the Zintl line. The last two terms instead refer to a vertical line sometimes drawn between groups 13 and 14.
