What are some of Calciums properties?
Physical properties Calcium is a fairly soft metal with a shiny silver surface when first cut. The surface quickly becomes dull as calcium reacts with oxygen to form a coating of white or gray calcium oxide. Calcium’s melting point is 850°C (1,560°F) and its boiling point is 1,440°C (2,620°F).

Chemical properties of beryllium – Health effects of beryllium – Environmental effects of beryllium Atomic number 4 Electronegativity according to Pauling 1.5 Density 1.86 g.cm – 3 Melting point 1280 °C Boiling point 2970 °C.
What are some chemical properties for calcium?
Calcium’s symbol is “Ca” and has an atomic number 20, with atomic weight 40.078amu. The chemical properties of calcium include its melting point, which is 839.0 +/- 2°C while its boiling point is 1484.0ºC with a valence of 2. This means that calcium needs more than 14 times of needed heat to boil water.
What are the properties of phosphorus?
Ordinary phosphorus is a waxy white solid. It is colorless and transparent in its pure form. Phosphorus is insoluble in water, but soluble in carbon disulfide. Phosphorus burns spontaneously in air to its pentoxide.
What is oxygen physical properties?
In normal conditions oxygen is a colourless, odourless and insipid gas; it condensates in a light blue liquid. Oxygen is part of a small group of gasses literally paramagnetic, and it’s the most paramagnetic of all. Liquid oxygen is also slightly paramagnetic.
What are Sodiums properties?
It’s a soft metal, reactive and with a low melting point, with a relative density of 0,97 at 20ºC (68ºF). From the commercial point of view, sodium is the most important of all the alkaline metals. Sodium reacts quickly with water, and also with snow and ice, to produce sodium hydroxide and hydrogen.
What are the properties and uses of beryllium?
Beryllium is a silvery-white metal. It is relatively soft and has a low density. Beryllium is used in alloys with copper or nickel to make gyroscopes, springs, electrical contacts, spot-welding electrodes and non-sparking tools. Mixing beryllium with these metals increases their electrical and thermal conductivity.
Is beryllium stronger than titanium?
The specific rigidity of beryllium is around six times greater than that of any other metal or alloy. Titanium, and it alloys. Magnesium and its alloys. Aluminium and its alloys.
What are 2 chemical properties of boron?
Chemical properties of boron – Health effects of boron – Environmental effects of boron Atomic number 5 Electronegativity according to Pauling 2.0 Density 2.3 g.cm – 3 at 20°C Melting point 2076 °C Boiling point 3927 °C.
What are 3 physical properties of calcium?
Physical Properties Properties Metric Imperial Density 1.54 g/cm 3 0.055 lb/in 3 Melting point 837-841 °C 1540-1550 °F Boiling point 1484°C 2703°F.
Is calcium a good conductor of electricity?
While calcium is a poorer conductor of electricity than copper or aluminium by volume, it is a better conductor by mass than both due to its very low density.
What are the chemical properties?
A chemical property is a characteristic of a particular substance that can be observed in a chemical reaction. Some major chemical properties include flammability, toxicity, heat of combustion, pH value, rate of radioactive decay, and chemical stability.
What are the dangers of phosphorus?
CHEMICAL DANGERS: Phosphorus spontaneously ignites on contact with air, producing toxic fumes (phosphorus oxides). Phosphorus reacts violently with oxidants, halogens, some metals, nitrites, sulfur, and many other compounds, causing a fire and explosion hazard.
What are 3 uses of phosphorus?
Today most of our phosphorus comes from phosphate rock that is mined around the world, and then converted to phosphoric acid. Fifty million tonnes are made every year and it has multiple uses. It is used to make fertilisers, animal feeds, rust removers, corrosion preventers, and even dishwasher tablets.
What is unique about phosphorus?
Phosphorus is a poor conductor of heat and electricity, except black phosphorus. All types of phosphorus are solid at room temperature. The white form (sometimes called yellow phosphorus) resembles wax, the red and violet forms are noncrystalline solids, while the black allotrope resembles graphite in pencil lead.
What are 4 physical properties of oxygen?
Oxygen is a colorless, odorless, tasteless gas. It changes from a gas to a liquid at a temperature of -182.96°C (-297.33°F). The liquid formed has a slightly bluish color to it. Liquid oxygen can then be solidified or frozen at a temperature of -218.4°C (-361.2°F).
Does oxygen have chemical properties?
Chemical Properties of Oxygen At standard temperature and pressure (STP), two atoms of the element bind to form dioxygen, a colorless, odorless, tasteless diatomic gas with the formula O2. Oxygen is a strong oxidizing agent and has the second-highest electronegativity of all reactive elements, second only to fluorine.
What are the physical and chemical properties of hydrogen?
At standard temperature and pressure, hydrogen is a nontoxic, nonmetallic, odorless, tasteless, colorless, and highly combustible diatomic gas with the molecular formula H2. Hydrogen is also prevalent on Earth in the form of chemical compounds such as hydrocarbons and water.
What are Sodiums uses?
Sodium is used as a heat exchanger in some nuclear reactors, and as a reagent in the chemicals industry. But sodium salts have more uses than the metal itself. The most common compound of sodium is sodium chloride (common salt). It is added to food and used to de-ice roads in winter.
What is the chemical symbol of chlorine?
Cl
What is a chemical property of salt?
Salt is a chemical compound with a number of interesting properties: Crystals or white crystalline powder. Transparent and colourless in crystalline form – rather like ice. Crystallises in the isometric system, usually in the form of cubes.
What are some physical properties of beryllium?
Beryllium is a steel gray and hard metal that is brittle at room temperature and has a close-packed hexagonal crystal structure. It has exceptional stiffness (Young’s modulus 287 GPa) and a melting point of 1287 C. The modulus of elasticity of beryllium is approximately 50% greater than that of steel.
What makes beryllium unique?
Uniquely strong and light, beryllium is used to make cell phones, missiles and aircrafts. Steel gray in color, beryllium’s modulus of elasticity is about one-third greater than steel. Beryllium is nonmagnetic and resistant to concentrated nitric acid.
What are the advantages of beryllium?
Beryllium contributes hardness, strength, high electrical and thermal conductivity, and resistance to corrosion, wear, and fatigue. For example, BeCu springs “bounce back” to their original shape again and again.
