Who am I ? (Round 2)

      I'm a metal that's soft and low,

In your hand, I'll start to flow.

With a melting point that's quite a show,

I'm used in mirrors that truly glow.

Who am I?

Answer explanation

Gallium is a metal that is soft and can melt in your hand, as it has a melting point of about 29.76 °C (85.57 °F). It is often used in mirrors and other reflective coatings due to its ability to form a reflective surface when applied as a thin film.

I'm noble and rare, in the air I reside,

With a glowing white light, I cannot hide.

In jewellery and labs, I reign supreme.

Resistant to tarnish, a noble might,

Who am I?

Answer explanation

Platinum is a precious and rare metal with a silvery gleam. It is highly valued in jewelry for its beauty and resistance to tarnish, making it a noble metal. Additionally, platinum is widely used in laboratory equipment and industrial applications due to its excellent resistance to corrosion and high melting point.

I'm a metal of power, radioactive might,

In bombs and reactors, I cause quite a fright.

Named for a distant god, I shine with decay,

Handle with care, my half-life holds sway.

Who am I?

Answer explanation

Plutonium is a powerful, radioactive metal used in nuclear reactors and atomic bombs, which makes it both feared and respected. It is named after Pluto, the distant Roman god of the underworld. Plutonium undergoes radioactive decay and must be handled with great care due to its hazardous nature and significant half-life.

      I'm a metal, heavy but safe, and you see,

In cosmetics and medicine, I help thee.

When I cool, I show colors, quite the art,

With steps and hues, I set myself apart.

Who am I ?

Answer explanation

Bismuth is a heavy metal that is safe for use in cosmetics and medicine. It is known for its colorful, iridescent oxide surface when it cools, displaying a spectrum of colors. Bismuth compounds are used in products like Pepto-Bismol and in various cosmetics, setting it apart with its unique properties and applications.

    I'm a metal, rare and gray,

In jet engines, I come to play.

With platinum I often pair, High melting point beyond compare.

Who am I?

Answer explanation

Rhenium is a rare, gray metal used in jet engines and gas turbines due to its high melting point and excellent heat-resistant properties. It is often alloyed with platinum for use in catalytic converters and other high-performance applications.

      In history's dark tales, I play a grim part,

A metalloid element, both science and art.

In pigments and poisons, my presence is found,

In groundwater, sometimes, I quietly abound.

Who am I ?

Answer explanation

Arsenic is a metalloid element that has played a dark role in history due to its toxic properties. It has been used historically in poisons and pigments. Arsenic contamination can also occur in groundwater, posing serious health risks. Despite its toxicity, arsenic compounds have also been used in various industrial and artistic applications.

     I'm rare and elusive, you might say I'm shy,

 In the halogen group, I quietly lie.

Radioactive and fleeting, hard to hold tight,

In cancer treatment, I help in the fight.

Who am I?

Answer explanation

Astatine is a rare and radioactive halogen element. It is one of the least abundant elements in the Earth's crust and is typically found in trace amounts due to its radioactive decay. Astatine is highly reactive and unstable, making it difficult to study and isolate in pure form. Despite its rarity and fleeting nature, astatine isotopes have been used in scientific research and potentially in cancer treatment due to their radioactive properties.
