Question

what is titanium ?give example of metalloid.​

Answer 1

Answer:

silvery-gray light strong metallic element with atomic number 22 obtained from ilmenite and rutile and used especially in alloys, refractory materials, pigments, and medical and dental devices — see Chemical Elements Table.

Explanation:

Metalloid

• Chemical element.
• Boron.
• Semiconductor.
• Arsenic.

• Selenium.
• Antimony.
• Germanium.

Answer 2

Titanium:-

Titanium(Ti) is a metal light, silvery-grey ,chemical element.Its atomic number is is 22 and atomic weight is 47.9.It belongs to group - 4.

Properties:-

• Strong, lustrous, corrosion-resistant
• Pure titanium is not soluble in water but soluble in concentrated acids.
• It forms a passive but  a protective oxide coating as a corrosion resistance when exposed to elevated temperatures in air but at room temperatures it resists tarnishing.

• Main oxidation state is 4+.
• 3+ and 2+ are less stable.

Metalloid:-

A chemical element that has properties that are intermediate to that of a typical metal and a typical non-metal is known as a Metalloid.

Examples:

• Boron
• Arsenic
• Germanium
• Silicon
• Antimony
• Tellurium

Some properties:-

✦ Metalloids are good semi-conductors.

✦ Their reactivity depends on the properties of elements they react with.

✦When they are mixed with metals,they form alloys.

✦They can form glasses.
