Oxygen therefore oxidizes metals to form salts in which the oxygen atoms are formally present as O 2-ions. Rust forms, for example, when iron reacts with oxygen in the presence of water to give a salt that formally contains the Fe 3+ and O 2- ions, with an average of three water molecules coordinated to each Fe 3+ ions in this solid.

Reactivity Series of Metals - Get the Chart, Significance …

In the reactivity series, as we move from bottom to top, the reactivity of metals increases. Metals present at the top of the series can lose electrons more readily to form positive ions and corrode or tarnish more readily. They require more energy to be separated from their ores, and become stronger reducing agents, while metals present at the bottom of the series are good oxidizing agent.

Using electron configurations, explain why the halogens …

Halogen react with alkali metals because of their valence electrons. Halogens are just one electron short of being a stable wanna be "noble gas" so they "take or borrow" an electron. alkali metals have one too many valence electrons to be a noble gas, so they "give

2016/1/26· The problem tells you that #"6 g"# of hydrogen gas, #"H"_2#, react with an unknown mass of oxygen gas, #"O"_2#, to form #"54 g"# of water. As you know, the law of mass conservation tells you that the in a chemical reaction the total mass of the reactants …

Reactions of the Group 2 elements with air or oxygen

2020/8/8· On the whole, the metals burn in oxygen to form a simple metal oxide. Beryllium is reluctant to burn unless it is in the form of dust or powder. Beryllium has a very strong (but very thin) layer of beryllium oxide on its surface, and this prevents any new oxygen getting at the underlying beryllium to react …

Oxygen, nitrogen and the rare gases - Essential Chemical …

Except for helium, which is mostly extracted from natural gas, oxygen, nitrogen and the other rare gases are extracted from the air that makes up Earth''s atmosphere. Unlike the sources of some chemicals there are therefore no concerns about the depletion of this resource and if a sample of air is used to produce one of the gases, there are no problems about venting the ''waste gases'' back into
