Explanation

Bromine is the only non-metal that remains in liquid form at room temperature.

It is a reddish-brown liquid with a strong odor and is highly reactive.

Explanation

The ability of metals to be drawn into thin wires is known as ductility.

This property allows metals to be stretched without breaking.

This making them useful in various applications.

Explanation

Steel is the most elastic material

Because it returns to its original shape more effectively after being deformed than the other materials listed.

Explanation

Copper, gold, and silver are named coinage metals.

Because they have historically been used to mint coins.

Due to their malleability and resistance to corrosion.

Explanation

The hardest substance in the world is diamond.

Its hardness is due to the strong covalent bonding between its carbon atoms.

This making it the most resistant to scratching.

Category: Native minerals

Cleavage: 111 (perfect in four directions)

Crystal class: Hexoctahedral (m3m); H-M symbol: (4/m 3 2/m)

Crystal habit: Octahedral

Crystal system: Cubic

Dana classification: 1.3.6.1

Density: 3.5–3.53 g/cm3 3500–3530 kg/m3

Explanation

Nuclear power plants primarily use a specific type of uranium 235 for nuclear fission

because its atoms are easily split apart.

*******

Uranium's most stable isotope, uranium-238,

has a half-life of about 4,468,000,000 years.

Uranium-238 is not fissile, but is a fertile isotope,

because after neutron activation it can produce plutonium-239, another fissile isotope.

Explanation

Lead is commonly used in lead-acid batteries, which are widely used in automotive applications and for backup power systems.

Lead-acid batteries are known for their reliability and relatively low cost. 

Explanation

Sodium hypochlorite (NaClO), usually as a 3–6% solution in water

It is usually called "liquid bleach" or just "bleach"

Sodium hypochlorite acts as a powerful disinfectant and stain remover, making it effective for various cleaning and sanitizing purposes.

Explanation

A closely wound cylindrical coil of insulated wire is called Solenoid.

Solenoid is a cylindrical coil of wire acting as a magnet when carrying electric current.
