Why does silicon have a larger atomic radius than carbon?
Size. As expected silicon is larger than carbon due to the presence of a second shell: i.e., C = 1s2 2s2 2p2 while Si = 1s2 2s2 2p6 3s2 3p2. A comparison of the relative sizes of carbon and silicon are given in Table. Atomic, covalent, and van der Waals radii of carbon and silicon.
Is a carbon atom bigger than a silicon atom?
Like carbon, it can share those electrons with other silicon atoms. Because silicon atoms are about one and a half times larger in diameter that carbon atoms, however, the atoms can not pack as tightly and therefore can not to bond into long -Si-Si-Si-Si-chains that allow as much access as do carbon chains.
Will silicon have a larger or smaller atomic radius than carbon?
Answer: In silicon, the electrons spread into the 3rd energy level, whereas in carbon, it is only to the 2nd energy level. This difference occurs because of carbon in the 2nd period, but silicon in the 3rd. Silicon atom is larger than the carbon atom.
Is germanium bigger than carbon?
c. Germanium has a greater atomic radius because it is in period 4 and thus has 4 energy levels (while carbon is in period 2 and only has 2 energy levels).
Why carbon has more density than silicon?
The catenation bonds of silicon are very weak. C-C bond is much stronger than Si-Si bond ; thus silicon bonds break easily. Hence compounds of Carbon are much more stable than Silicon.
Which has a larger atomic radius?
francium
Atomic radii vary in a predictable way across the periodic table. As can be seen in the figures below, the atomic radius increases from top to bottom in a group, and decreases from left to right across a period. Thus, helium is the smallest element, and francium is the largest.
Is germanium bigger than silicon?
Tin is a metal with a high conductivity. Silicon and germanium are similar to each other and have an intermediate conductivity. They are called semiconductors….Electrical Conductivity.
Element | Conductivity (S/m) |
---|---|
carbon | 0.001 |
silicon | 1 x 103 |
germanium | 2 x 103 |
tin | 9.1 x 106 |
Is silicon denser than carbon?
Silicon dioxide (which is also known as silicates) is a monosaccharide made up of one hydrogen atom with two electrons. In a compound of carbon and oxygen, silicon is substituted for carbon with the same value of density as silicon dioxide. 2.33g/cm3 is the density of silicon contant.
How to compare silicon and carbon?
Compare Silicon and Carbon on the basis of their properties, attributes and periodic table facts. Compare elements on more than 90 properties. All the elements of similar categories show a lot of similarities and differences in their chemical, atomic, physical properties and uses.
What is the periodic table of silicon?
Silicon – Periodic Table. Silicon is a 14. chemical element in the periodic table of elements. It has 14 protons and 14 electrons in the atomic structure. The chemical symbol for Silicon is Si.
How many protons and electrons does silicon have?
Silicon is a chemical element with atomic number 14 which means there are 14 protons and 14 electrons in the atomic structure. The chemical symbol for Silicon is Si. Silicon is a hard and brittle crystalline solid with a blue-grey metallic lustre, it is a tetravalent metalloid and semiconductor.
What is the standard atomic weight of silicon (Si)?
Standard atomic weight A r, std (Si) [28.084, 28.086] conventional: 28.085: Silicon in the periodic table
