So the metal which is soft is sodium and the non metal which is hard is diamond. Sodium is metal and is soft in nature because in its valence shell it has one electron present and the atomic size of it is large due to which it also does not have strong chemical bonding so it is soft.
Which is very soft metal?
Caesium is considered to be the softest metal, and Lead is considered one of the softest metals. Answer 3: Mercury at room temperature is liquid (molten). Gallium is liquid at body temperature, while solid (if soft) at room temperature.
What are the 2 soft metals?
Soft metals are those which can be cut and easy to dent, work, or cut without shattering, malleable. Sodium metal is soft enough to be cut with a knife. Potassium is also a soft metal.
What metal is soft and shiny?
Group 1A (or IA) of the periodic table are the alkali metals: hydrogen (H), lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). These are (except for hydrogen) soft, shiny, low-melting, highly reactive metals, which tarnish when exposed to air.
Which is the most softest metal?
Cesium is a rare, silver-white, shiny metal with brilliant blue spectral lines; the element’s name comes from “caesius,” a Latin word meaning “sky blue.” It is the softest metal, with a consistency of wax at room temperature.
Which metal is soft and easily cut with knife?
Sodium is silver white color metal with malleable and ductile property. It is the metal that can easily be cut with a knife. It is a good conductor of heat and electricity.
Which two metal are soft and can be easily cut with a knife?
sodium and potassium can be cut with a knife.
Which two metals are soft and can be cut with a knife?
Answer: Sodium Sodium metal is soft enough to be cut with a knife. Potassium is also a soft metal.
What is the softest metal list?
Cesium is considered the softest metal, Lead is also considered among the softest metals.
Which metal is the lightest metal in the world?
Magnesium: The Lightest Structural Metal Magnesium is the lightest structural metal and abundantly available in the earth’s crust and seawater. Magnesium is the third most commonly used structural metal, following steel and aluminum.
Is Aluminium a soft metal?
Pure aluminum (99.996 percent) is quite soft and weak; commercial aluminum (99 to 99.6 percent pure) with small amounts of silicon and iron is hard and strong. Ductile and highly malleable, aluminum can be drawn into wire or rolled into thin foil. The metal is only about one-third as dense as iron or copper.
What is the weakest type of metal?
Mercury is a liquid at room temperature. It has the weakest metallic bonding of all, as indicated by its bonding energy (61 kJ/mol) and melting point (−39 °C) which, together, are the lowest of all the metallic elements.
Which is the hardest metal in the world?
The Hardest Metals in the World Tungsten (1960–2450 MPa) Tungsten is one of the hardest metals you will find in nature. Iridium (1670 MPa) Steel. Osmium (3920–4000 MPa) Chromium (687-6500 MPa) Titanium (716 to 2770 MPa).
What metal is softer than gold?
Despite being more durable, platinum is a softer metal than gold. This means it will get scratched a little easier than gold would.
Which metal Cannot be cut easily with a knife?
No metal can be cut with a knife except Sodium (Na) and Potassium (K). Well, for the question, Chromium is the hardest metal.
Which is the hardest non metal?
Diamond Diamond Graphite Transparent and colourless Opaque and black Hard Soft.
Which non metal is stored in water?
Hence, Non – metal which is stored in water is Phosphorous.
Which metal is found in liquid state?
Mercury is the only liquid metal found at normal temperatures.
Which is the only non-metal found in liquid state?
Bromine is the only non-metal that is in liquid at room temperature.
Which non-metal is present in fertilizers?
Therefore, the answer is – option (c) – Phosphorus is a non-metal which is used for the manufacture of fertilizers.
Which metal do we use in day to day life?
Nickel, cobalt, and chromium are often found in everyday consumer objects, such as jewelry, clothing, leather, technological devices, household items, and other daily-use objects [1]. Gold, palladium, mercury, copper, aluminum, titanium, iron, platinum, tin, zinc are also occasionally found in these items.
Which two metals can be cut with knife explain why?
Answer: Sodium and potassium is the two metals which can be cut with knife.
Is paper a metal or non metal?
Paper can neither be metal nor a non-metal. A paper is a compound of cellulose obtained from trees. As we all know that metals, non-metals and metalloids are all elements of the periodic table.
Which is the hardest and softest metal?
Silver is the correct answer. Note: * Caesium is the softest metal with the Mohs hardness of 0.2. * Always remember, the hardness of gold, silver, aluminium, zinc, lanthanum, cerium, jet is in between 2.5-3 and that of platinum is 3.5 (according to Mohs hardness).
What is the softest material?
According to the Mohs scale, talc, also known as soapstone, is the softest mineral; it is composed of a stack of weakly connected sheets that tend to slip apart under pressure. When it comes to metals, scientists try to measure hardness in absolute terms.
Is CU a soft metal?
Copper is a chemical element with the symbol Cu (from Latin: cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity.
What is the lightest but strongest metal?
New Magnesium based alloy as World’s strongest and lightest metal to change the world. Researchers from North Carolina State University have developed a material using magnesium which is light like aluminum, but as strong as titanium alloys. This material has the highest strength-to-weight ratio known to mankind.
What is the most heaviest metal in the world?
Osmium is one of the heaviest materials on earth, weighing twice as much as lead per teaspoon. Osmium is a chemical element in the platinum group metals; it’s often used as alloys in electrical contacts and fountain pen nibs.
What is the lightest thing in the world?
Aerographene. Aerographene, also known as graphene aerogel, is believed to be the world’s lightest material with a density of just 0.16 milligram per cubic centimeter. Zhejiang University researchers developed the material, which is approximately 7.5 times less dense than air.
Is aluminium stronger than steel?
Aluminum is about one-third the weight of steel, meaning parts can be made thicker and stronger while still reducing weight in vehicles and other applications. Depending on the alloy and processing technique used, pound for pound aluminum can be forged to be just as strong if not stronger than some steel.
Why is aluminum a soft metal?
The few electrons are available for metallic bonding in aluminium metal are a probably cause for it being soft with a low melting point and low electrical resistivity.
Is Aluminum the lightest metal?
The first seven metals in the periodic table are lithium, beryllium, sodium, magnesium, aluminium, potassium and calcium, known collectively as the “lightest metals”.
