Which sample has maximum density?
The maximum density of water is at 4°C as there are two opposite effects that are in balance.
Why do metals have low density?
Since alkali metals have a large atomic size and low atomic weight, they have low density.
What are the top 10 densest metals?
The 10 Densest Metals:
- Osmium 22.6 g/cm^3. Similar to Iridium, osmium is a hard-brittle transition metal that looks bluish-white.
- Iridium 22.4 g/cm^3.
- Platinum 21.45 g/cm^3.
- Neptunium 20.2 g/cm^3.
- Plutonium 19.84 g/cm^3.
- Tungsten 19.35 g/cm^3.
- Gold 19.32 g/cm^3.
- Uranium 18.95 g/cm^3.

What is the softest metal?
Cesium
Which element is known as the softest heavy 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 is the softest material on earth?
Talc
Which element is known as the softest heavy metal?
Lead
Is silver the softest metal?
In their pure forms, gold and silver happen to be very soft metals—soft enough that you should be able to mark them with your teeth. According to the Mohs hardness scale—which relates pairs of materials according to which one will scratch the other first—gold scores a 2.5 and silver, which is harder, a 2.7.
Is gold a soft metal?
Although it is very strong, gold is the most malleable of all metals. Pure gold is too soft to withstand the stresses of everyday wear, so it is combined with different alloys to give it strength and durability. Even though 24kt is pure gold, it is extremely soft and not recommended for jewelry.
Which one of the following is the softest?
Which one of the following is the softest?
- Aluminium.
- Sodium.
- Lithium.
- Iron.
Is Lithium the softest metal?
Lithium is the softest metal in the periodic table.
Which alkali metal is the softest?
Potassium
Is iron the softest metal?
In its pure form iron is a fairly soft, grayish metal. It is very reactive and will readily corrode or rust. It is malleable and a decent conductor of electricity and heat. Iron is the most naturally magnetic of the elements.
Where can iron be found in nature?
Iron is found distributed in the soil in low concentrations and is found dissolved in groundwaters and the ocean to a limited extent. It is rarely found uncombined in nature except in meteorites, but iron ores and minerals are abundant and widely distributed.
Where is Iron most commonly found?
Iron is the fourth most abundant element, by mass, in the Earth’s crust. The core of the Earth is thought to be largely composed of iron with nickel and sulfur. The most common iron-containing ore is haematite, but iron is found widely distributed in other minerals such as magnetite and taconite.
Is iron found pure in nature?
Source: Iron is not found free in nature but is found in iron ores such as hematite (Fe2O3), magnetite (Fe3O4) and taconite. Commercially, iron is produced in a furnace at temperatures of about 2000 oC by the reduction of hematite or magnetite with carbon.
