What is element No 76?

What is element No 76?

Osmium is a chemical element with symbol Os and atomic number 76. Classified as a transition metal, Osmium is a solid at room temperature.

What type of substance is tungsten?

tungsten (W), also called wolfram, chemical element, an exceptionally strong refractory metal of Group 6 (VIb) of the periodic table, used in steels to increase hardness and strength and in lamp filaments.

What element has an atomic mass of 76?

Osmium
The elements of the periodic table sorted by atomic mass

What can break osmium?

Osmium is dissolved by acids or by aqua regia only after long periods of exposure to the liquids. When heated, the metal combines with oxygen to form osmium tetroxide (OsO4). Osmium tetroxide is very toxic and the only important commercial compound of osmium.

What is cesium used for?

Caesium is a soft, gold-coloured metal that is quickly attacked by air and reacts explosively in water. The most common use for caesium compounds is as a drilling fluid. They are also used to make special optical glass, as a catalyst promoter, in vacuum tubes and in radiation monitoring equipment.

How many electrons the element with atomic number of 76 has?

Osmium Atomic and Orbital Properties Osmium atoms have 76 electrons and the electronic shell structure is [2, 8, 18, 32, 14, 2] with Atomic Term Symbol (Quantum Numbers) 5D4.

Is tungsten stronger than diamond?

Tungsten metal is rated at about a nine on the Mohs scale of hardness. A diamond, which is the hardest substance on earth and the only thing that can scratch tungsten, is rated at a 10.

What does osmium smell like?

Osmium tetroxide has a characteristic, unpleasant, irritating odour similar to that of chlorine and ozone with a touch of garlic.

Is osmium stronger than diamond?

Researchers from us-based Lawrence Livermore National Laboratory (llnl) have discovered that osmium, a metal, is harder than diamond. It withstands compression better than any other material.

Can osmium be melted?

Physical properties They are also among the highest of all elements. Osmium is unworkable as a metal. It cannot be melted and shaped like most metals.

What happens if you eat cesium?

HIGHLIGHTS: Exposure to stable or radioactive cesium occurs from ingesting contaminated food or drinking water or breathing contaminated air. High levels of radioactive cesium in or near your body can cause nausea, vomiting, diarrhea, bleeding, coma, and even death.

How do we use cesium in everyday life?

Cesium is used to help drill oil and make vacuum tubes. The most common everyday use for cesium is with the GPS on your cell phone. Cesium clocks is the more accurate term for atomic clocks, since cesium is used in these clocks.

What is the name of an element with 190 neutrons and protons and 76 electrons?

Osmium-190 is composed of 76 protons, 114 neutrons, and 76 electrons. Osmium-192 is composed of 76 protons, 116 neutrons, and 76 electrons.

Is Rh a metal?

rhodium (Rh), chemical element, one of the platinum metals of Groups 8–10 (VIIIb), Periods 5 and 6, of the periodic table, predominantly used as an alloying agent to harden platinum. Rhodium is a precious, silver-white metal, with a high reflectivity for light.

Are diamonds bulletproof?

Diamond Armor is certified bulletproof by NATO standards, waterproof thanks to nano-technology sealing and has an EMPA air conditioning system in-built to keep the wearer cool.

Can gold stop a bullet?

Gold Flex is lighter than woven Kevlar, Twaron and other Ballistic material. According to the manufacturer, Gold Flex offers superior bulletproof protection.

Is osmium safe to touch?

Osmium tetroxide, OsO4, is highly toxic. Concentrations in air as low as 10-7 g m-3 can cause lung congestion, skin damage, and severe eye damage. The oxide, in particular, should only ever be handled by a properly qualified chemist.

Is osmium rarer than gold?

Funnily enough, Os is considered as a platinum group metal. Additionally it is much rarer than gold, about 1000 times.

Is osmium bulletproof?

Osmium is not likely to make a good armor because of its weight. Its tensile strength is 1000 MPa (which sounds good), but with the density of 22.5 g/cm3, its Specific strength is only 44.4 kN·m/kg, which is lower than steel, titanium or any of the special bullet-protecting materials.
