"Semi-metals" Meaning
Semi-metals, also known as metalloids or semimetals, are a small group of elements that exhibit some characteristics of metals and some characteristics of nonmetals.
Semi-metals are typically found on the border between metals and nonmetals in the periodic table, and they have properties that are intermediate between those of metals and nonmetals. They tend to be relatively brittle, have a dull appearance, and do not conduct electricity well.
There are six semi-metals in the periodic table:
1. Boron (B)
2. Silicon (Si)
3. Germanium (Ge)
4. Arsenic (As)
5. Antimony (Sb)
6. Tellurium (Te)
Some of the key characteristics of semi-metals include:
They are relatively brittle and lack the malleability of metals.
They have a dull appearance, unlike the shiny appearance of metals.
They do not conduct electricity well, although they are not as poor as nonmetals.
They have a high melting and boiling point, indicating high interatomic forces.
They exhibit some properties of metals, such as forming positive ions.
Overall, semi-metals play a vital role in the electrical and electronic industries, particularly in the production of semiconductors.
