What element has the larger first ionization energy cesium or potassium?
Cesium has a larger first ionization energy compared to potassium. This is because cesium is located further down the periodic table in the alkali metal group, meaning it has a larger atomic radius and a lower effective nuclear charge, both of which make it easier to remove an electron from potassium than from cesium.
Which is the highest energy orbital for a silicon atom?
3p is the highest "occupied" orbital of an "unexcited" neutral Silicon atom.
Why does silicon has higher boiling point than phosphorus?
phosphorus has weak inter molecular forces(vander waals) between molecules,where as silicon has giant structure,so it has strong bonds .....takes more energy to break bonds,so higher bp and mp
How many outer levels does Cesium have?
One electron in outermost energy level.
What is the flame color of cesium?
The flame color of cesium is typically described as a sky-blue or violet color. When cesium is burned, the electrons in the cesium atoms get excited and emit energy in the form of light, producing the characteristic flame color.
Does potassium has a higher ionization energy than cesium?
No, cesium has a lower ionization energy than potassium. This is because cesium has a larger atomic size and a weaker attraction between the nucleus and the outermost electron compared to potassium.
What is the chemical name for SiS2?
the answer is cesium silicon fluoride Cs= cesium (on periodic table), Si= silicon (periodic table) and F= fluorine (periodic table) but F is a negative so, Fluorine turns to Fluoride..."ide" means negatively charged.
Which atom lithium or cesium needs more energy to become an ion?
Cesium needs more energy to become an ion than lithium because cesium has a higher ionization energy due to its larger atomic size and greater distance of valence electrons from the nucleus. This makes it more difficult to remove electrons from cesium compared to lithium.
What element has the larger first ionization energy cesium or potassium?
Cesium has a larger first ionization energy compared to potassium. This is because cesium is located further down the periodic table in the alkali metal group, meaning it has a larger atomic radius and a lower effective nuclear charge, both of which make it easier to remove an electron from potassium than from cesium.
Which is the highest energy orbital for a silicon atom?
3p is the highest "occupied" orbital of an "unexcited" neutral Silicon atom.
How many electrons does Cesium have in its outer energy level?
Cesium, or Cs, has 1 valence electron.
Why cesium requires little energy to release its one elecron of outermost shell?
The distance between the nucleus an this electron is higher.
What is difference between silicon and germanium semiconductors?
Silicon has a higher operating temperature and greater thermal stability compared to germanium. Silicon has a larger bandgap energy which makes it better suited for high-power applications. Germanium has a higher electron mobility which can result in faster transistors, but it is less commonly used in modern semiconductor devices.
Why cut in voltage of silicon is more than that of germanium?
Silicon has a larger band gap energy than germanium, resulting in a higher cut-in voltage for silicon diodes compared to germanium diodes. The larger band gap in silicon means that it requires more energy for electrons to be excited into the conduction band, resulting in a higher cut-in voltage.
Why does silicon dioxide have a higher melting point than silicon tetra chloride?
Silicon dioxide has a higher melting point than silicon tetrachloride because silicon dioxide forms a network solid structure with strong covalent bonds, requiring more energy to break compared to the weaker forces holding silicon tetrachloride molecules together. Additionally, silicon dioxide molecules are larger and have a higher molecular weight, contributing to a stronger intermolecular forces between the molecules.
How many energy shells does silicon have in it?
Silicon has 3 energy shells.
Why is the first ionization energy of aluminium is less than the first ionisation energy of silicon?
Al has atomic number 13, and silicon has atomic number 14. The extra electron that silicon has is in a 3p orbital. In simple terms the extra charge on the silicon nucleus contracts the electron shell, this increases the energy to remove an electron and also decreases the atomic radius. Al, first ionization energy 577.5 kJ/mol, atomic radius 125pm Si, first ionization energy 786.3 kJ/mol, atomic radius 110pm
