Magnesium » reactions of elements - Periodic table

Once ignited, magnesium metal burns in air with a characteristic blinding bright white flame to give a mixture of white magnesium oxide, MgO, and magnesium nitride, Mg 3 N 2. Magnesium oxide is more normally made by heating magnesium carbonate. Calcium, immediately below magnesium in the periodic table is more reactive with air than magnesium.

Health effects of metals in drinking water

Non-corroding pluing materials, such as plastic or polyvinyl chloride (PVC) may be used if old pipes must be replaced. Metal concentrations in tap water are highest after water has rested in the pluing system for a long time. Before drinking each morning, run your cold water several minutes to flush metals which have accumulated overnight.

Is iron a metal or non metal and why? | Yahoo Answers

Dec 14, 2008· yes it is a metal because it has few valence electrons (on the left side of the periodic table) and in elemental form (the iron metal) it exists as metallically bonded (the electrons flow around freely). Also it forms ionic bonds with non metals like with oxygen (iron oxide)

7.6: Metals, Nonmetals, and Metalloids - Chemistry LibreTexts

Alkali metals are always 1 + (lose the electron in s subshell) Alkaline earth metals are always 2 + (lose both electrons in s subshell) Transition metal ions do not follow an obvious pattern, 2 + is common, and 1 + and 3 + are also observed; Compounds of metals with non-metals tend to be ionic in nature.

Reactivites of Metals

Some metals react with water to form hydroxides and hydrogen gas. However, some metals do not react with water but steam to form metal oxides and hydrogen gas. metal + water metal hydroxide + hydrogen gas. metal + steam metal oxide + hydrogen gas

Reactivity series - Wikipedia

In chemistry, a reactivity series (or activity series) is an empirical, calculated, and structurally analytical progression of a series of metals, arranged by their "reactivity" from highest to lowest. It is used to summarize information about the reactions of metals with acids and water, double displacement reactions and the extraction of metals from their ores.

Like most metals it has a close-packed crystalline structure, and forms a ion in aqueous solution. The reason why, in a few cases, aluminium is referred to as a metalloid, from the article: It has some properties that are unusual for a metal; taken together, these are sometimes used as a basis to classify aluminium as a metalloid.
