The electrostatic force between a valence electron and the nucleus in silicon is ___________ than that in carbon. (stronger or weaker)
Due to this difference in force, the atomic radius of silicon is ____________ than that of carbon. (larger or smaller)
Homework Answers
electronic configuration of carbon=[He] 2s2 2p2
electronic configuration of silicon=[Ne] 3s2 3p2
it can be seen that in silicon valence electrons are more far away from nucleus than in carbon and in case of silicon shielding by inner electrons will be high.
The electrostatic force between a valence electron and the nucleus in silicon is __weaker_________ than that in carbon.
Due to this difference in force, the atomic radius of silicon is __larger__________ than that of carbon.
atomic radius of carbon=70 picometer
atomic radius of silicon=210 picometer
thank you

Effective Nuclear Charge and Periodic Trends Coulombs Law describes the interaction between two charges and varies by the magnitude of these charges and inversely with the distance between them. ? ∝ ?1?2/? For atoms, we’ll label the charges as the nuclear charge and electron charge. ? ∝ ?????????/? As you go up in atomic number (Z), the number of protons in the nucleus increases, making the charge on the nucleus increase, so that in general. ???? = ? ∙ (+1)...

Multiple Choice: Please select the best answer and dick "submit." How does the electrostatic force compare with the strong nuclear force in the nucleus of an atom? The electrostatic force is weaker and acts over longer distances. The electrostatic force is stronger and is only repulsive. The electrostatic force is weaker and is only attractive. The electrostatic force is stronger and acts over shorter distances.

The gap between valence and conduction bands in silicon is 1.12 eV. A nickel nucleus in an excited state emits a photon with wavelength 5.87x10-4 nm. How many electrons can be excited from the top of the valence band to the bottom of the conduction band by the absorption of this gamma ray? Provide your answer in mega electrons (mega x106).
Question 4 (1 point) Do you predict 52- or Ca2+ to have a smaller ionic radius?...
Question 4 (1 point) Do you predict 52- or Ca2+ to have a smaller ionic radius? Why? Ca2+ is smaller because it has only two valence electrons whereas S2- has six. OCa2+ is smaller because its nucleus has a larger positive charge which exerts a stronger force than the nucleus of S2- on the same number of electrons. Os2- is smaller because it contains fewer electrons than Ca2+ and therefore has a smaller electron cloud. OS2- is smaller because it...

22. Select the correct statements below. L. An atom of chlorine is larger than sulfur because the addition of an electron increases the repulsions without an increase in attraction for the nucleus resulting in less screening. An atom of oxygen is smaller than an atom of carbon because the distance of the valence electrons remains the same while the attraction for the nucleus increases with increasing number of protons. III. An atom of potassium is smaller than an atom of...
