Apart from Silicon, the following elements are considered as semi-metal(metalloids) :-
- Boron
- Germanium
- Arsenic
- Antimony
- Tellurium
- Polonium
However, not all sources consider Polonium to be metalloid whereas some allotropes of elements like phosphorous, selenium etc. also show metalloidic behavior.
What else can I help you with?
Is a semi metal hard?
Their hardness will be less than that of metals but more than that of non metals. Hence the name, semi metals or metalloids.
What non metal has 4 valence electronsproperties similar to carbon and an atomic mass slightly less than phosphorus?
The non-metal that fits this description is silicon. Silicon is located below carbon in the periodic table, has 4 valence electrons, and its atomic mass is slightly less than phosphorus. Like carbon, silicon can form covalent bonds and exhibits similar properties in terms of bonding and structure.
Which element is a semi-conductor of electricity?
Most conductors conduct both heat and electricity well. A semiconductor is a conductor whose resistance is between that of a conductor and an insulator. An example of a semiconductor is silicon which is used in electronic appliances
Who has more protons neon or Silicon?
Silicon has 14. Germanium has 32. You figure it out.
Which the most abundant metal in the Earth crust?
Depends. What do you consider a metal?If you're an astronomer, it's oxygen. Chemists will laugh at you for saying this, but astronomers (well, some astronomers) divide the elements into "hydrogen, helium, and everything else, which for short we'll call 'metals'". On the cosmological scale, there's some justification for this, as hydrogen and helium are a lot more abundant in the universe as a whole than anything else.Even if we exclude oxygen as a clear non-metal (in chemical terms), the next most abundant element is silicon, and it's possible to get into all kinds of arguments over whether silicon is a "metal" or not.The next one after silicon is aluminium, and most people would agree that aluminium is a metal, though a few might quibble and say it's really a metalloid/semi-metal along with silicon.After that comes iron, which is the most abundant element in the crust where no one can reasonably make a case that it's anything but a metal.
Are there any pure forms of semi conductors other than germanium and silicon?
gaAs is semiconductor
Is silicon more reactive than sulfur?
Because Aluminum comes before Silicon in the dictionary
Is the element silicon ductile?
No, it is a semi conductor so it is not ductile.
Is sodium larger than silicone?
Sodium is smaller than silicon. Sodium is a metal, and silicon is a non-metal. In the periodic table, elements are arranged in order of increasing atomic number from left to right and top to bottom, so sodium, being to the left and below silicon, is smaller in size.
Is a semi metal hard?
Their hardness will be less than that of metals but more than that of non metals. Hence the name, semi metals or metalloids.
Is silicon brittle?
silicon is actually quite ductile as it is a metal
Does silicon react readily with other elements?
Silicon is a non-metal element that is not very reactive. It usually forms covalent bonds rather than ionic bonds with other elements. It reacts with oxygen at high temperatures to form silicon dioxide, but it does not readily react with most other elements at room temperature.
Does iron form more covalent bonding than silicon?
No. Since silicon is a non-metal, it has a greater tendency to engage in covalent bonding as compared to iron
Which is more metallic aluminum or silicon?
Aluminum, of course. Silicon is a metalloid while Aluminum is a metal.
What non metal has 4 valence electronsproperties similar to carbon and an atomic mass slightly less than phosphorus?
The non-metal that fits this description is silicon. Silicon is located below carbon in the periodic table, has 4 valence electrons, and its atomic mass is slightly less than phosphorus. Like carbon, silicon can form covalent bonds and exhibits similar properties in terms of bonding and structure.
Why is silicon a better semiconductor than germanium?
Silicon has a higher operating temperature and better thermal stability compared to germanium, making it more reliable for electronic devices. Additionally, silicon's oxide layer forms a better insulating material for integrated circuits, enhancing its performance. Silicon also has a wider bandgap than germanium, allowing for better control of electrical conduction.
Why is silicon similar to a non-metal?
Silicon is similar to a non-metal because it is a metalloid, which means it has properties of both metals and non-metals. Silicon has a half-filled outer electron shell, making it have some characteristics more similar to non-metals like carbon than typical metals. Additionally, silicon does not conduct electricity as well as metals do, further aligning it with non-metal properties.
