Demonstrations - Sodium + Chlorine

Sodium + Chlorine: Pass the Salt, Please . Sodium is a silver-colored metal which is soft enough to cut with a knife. It is an extremely reactive metal, and is always found naturally in ionic compounds, not in its pure metallic form. Pure sodium metal reacts violently (and sometimes explosively) with water, producing sodium hydroxide, hydrogen

Calcium metal reacts with water -

May 13, 2015· Calcium metal is second group alkaline earth metal. when it reacts with water it produces Hydrogen gas and Calcium hydroxide.

Aluminum:

The metal reacts violently with water, releasing hydrogen and usually igniting it. Throwing it in water sometimes causes liquid sodium to be expelled from the water due to the reaction and sprays around a wide area. It quickly reacts with air, requiring it to be stored in mineral oil or under argon.

Group 2 The Alkaline Earth Metals - Mr. Kent''s Chemistry

Chemically calcium is reactive and moderately soft for a metal (though harder than lead, it can be cut with a knife with difficulty). It is a silvery metallic element that must be extracted by electrolysis from a fused salt like calcium chloride.[1] Once produced, it rapidly forms a grey-white oxide and nitride coating when exposed to air.

Chemistry for Kids: Elements - Potassium

Characteristics and Properties Under standard conditions potassium is a soft silvery-white metal. It is so soft that it can be easily cut with a knife. When cut, the exposed metal tarnishes quickly and …

How to Defeat Calcium Scaling in Your Swimming Pool

Aug 22, 2017· Calcium scaling is an unsightly white to white-grey stain that forms on pool sides when a pool’s calcium levels and pH are ialanced. Although it may be difficult to do, calcium scales can be removed -- and preventative steps can be taken to keep them from reforming.

a element in group 1 on periodic table, very reactive & are only found in compounds, so shiny & soft they can easily be cut, like sodium & potassium, loses 1e- so it''s +1 alkaline earth metal an element in group 2 on periodic table, fairly hard, grey-white, good conductor, react by losing electrons, like magnesium & calcium, loses 2e- so it''s +2

Reactions of Main Group Elements with Water - Chemistry

Group 1: Alkali Metals. A common characteristic of most Alkali Metals is their ability to displace H 2 (g) from water. This is represented by their large, negative electrode potentials. In this event, the Group 1 metal is oxidized to its metal ion and water is reduced to form hydrogen gas and hydroxide ions.

Elements | Wyzant Resources

Potassium metal is a very soft metal that very quickly becomes tarnished in the air. The tarnishing can be slowed by storing the metal under kerosene. Potassium is a Group 1 element, an alkali metal. It reacts violently in water, burning with a bright blue-white flame. Not only are potassium ions not poisonous, but they are required by living

Sodium, Chemical Element - reaction, water, uses, elements

Physical properties Sodium is a silvery-white metal with a waxy appearance. It is soft enough to be cut with a knife. The surface is bright and shiny when first cut, but quickly becomes dull as sodium reacts with oxygen in the air. A thin film of sodium oxide (Na 2 O) forms that hides the metal itself.

Calcium - Wikipedia

Calcium is a chemical element with the syol Ca and atomic nuer 20. As an alkaline earth metal, calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to air.Its physical and chemical properties are most similar to its heavier homologues strontium and barium.It is the fifth most abundant element in Earth''s crust and the third most abundant metal, after iron and

18.1 Periodicity – Chemistry - opentextbc.ca

Group 2: The Alkaline Earth Metals. The alkaline earth metals (beryllium, magnesium, calcium, strontium, barium, and radium) constitute group 2 of the periodic table. The name alkaline metal comes from the fact that the oxides of the heavier meers of the group react …

Common Uses of Barium | Owlion

Barium is an interesting metal, with an interesting history, and an odd array of uses. While it is one of the most common elements found in the earth''s crust, your odds of finding it in elemental form on a morning stroll are exactly zero. It is a highly reactive metal which oxidizes quickly in air, creating barium carbonate, and barium peroxide.

Potassium Facts

Potassium is the second least dense metal after lithium. Potassium is a soft metal and can very easily by sliced. Argon or another suitable oil is used to store pure potassium, otherwise it will tarnish quickly. Potassium usually burns in a reaction with water. It reacts with the hydrogen in the

Tarnish - Wikipedia

It often appears as a dull, gray or black film or coating over metal. Tarnish is a surface phenomenon that is self-limiting, unlike rust. Only the top few layers of the metal react, and the layer of tarnish seals and protects the underlying layers from reacting.
