6/12/2007· c) to determine which metal or nonmetal is more reactive, compare elements within groups or periods (for diagonal predictions use Reactivity Series) Chemical Reactivity in a given period: _ For metals in a given period reactivity is determined by the nuer of electrons that must be transferred to a nonmetal.
A large percentage of proteins require metals to stabilize their structures or to carry out their functions. Zinc, one of the most common of these metals, is associated with proteins of a wide variety of biological roles. A recent study estimates that 40% of zinc binding
9/12/2010· All metal oxides are bases, with a few exceptions though copper is not one of those exceptions. Source(s ): My chem prof 0 0 0 Login to reply the answers Post noobslayer007 10 years ago Copper is a metal. Oxygen is a nonmetal. A metal reacted with a
The name of a metal ion is the same as the name of the metal atom from which it forms, so Ca 2+ is called a calcium ion. When atoms of nonmetal elements form ions, they generally gain enough electrons to give them the same nuer of electrons as an atom of the next noble gas in the periodic table.
19/6/2011· Metals: iron, copper, zinc, magnesium, gold, sodium, potassium, etc. You can view s-clock and d-block of periodic table to find more metals. Non metals: non metals are less in nuer than metals. Examples hydrogen, helium, oxygen, carbon, nitrogen, you will

Calcium is a chemical element with atomic nuer 20 which means there are 20 protons and 20 electrons in the atomic structure. The chemical syol for Calcium is Ca . Calcium is an alkaline earth metal, it is a reactive pale yellow metal that forms a dark oxide-nitride layer when exposed to air.
The periodic table of metals and nonmetals can be broken down to give you a sense of each element’s characteristics. Metals, nonmetals, and metalloids make up the periodic table, with metals constituting the large majority of all metals. The Periodic Table contains a lot of useful information on the elements.
For example, calcium is a group 2 element whose neutral atoms have 20 electrons and a ground state electron configuration of 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2. When a Ca atom loses both of its valence electrons, the result is a ion with 18 electrons, a 2+ charge, and an electron configuration of 1 s 2 2 s 2 2 p 6 3 s 2 3 p 6 .
