Q. Explain about Electron-Dot Structures?
Write an electron-dot structure for a impartial atom of arsenic an element used in semiconductor materials because of its electron configuration. Start by writing the electron configuration of arsenic. Utilize noblegas notation to emphasize the arrangement of electrons in the highest principal energy level. Arsenic is in the fourth(4th) period of the periodic table so the preceding noble gas is argon. Therefore arsenic's electron configuration will begin with the symbol [Ar] Arsenic has 15 electrons more than argon.
By means of the energy sublevel diagram you can see that the nineteenth electron begins the fourth principal energy level. Subsequent to the 4s sublevel is filled with two electrons ten electrons fill the 3d sublevel which is somewhat higher in energy than the 4s sublevel. Following the 3d sublevel is filled the remaining three electrons will be in orbitals in the 4p sublevel. Therefore the electron configuration for arsenic is [Ar]4s23d104p3.
Prior to writing the electron-dot structure for arsenic note that arsenic's ten 3d electrons aren't in the highest principal energy level. Consequently they aren't regarded as valence electrons. Merely the 4s and 4p electrons are valence electrons; therefore the electron-dot structure of arsenic has five dots as follows.

Correct configuration of Fe +3 [26] is: (1) 1s 2 , 2s 2 , 2p 6, 3s 2, 3p 6 , 3d5 (2) 1s 2 , 2s 2, sp 6 , 3s 2 , 3p 6 , 3d 3 , 4s 2 (3) 1s 2 , 2s 2 , 2p
1-methylcyclohexene Because 1-methylcyclohexene has dissimilar numbers of alkyl branches at the carbons of its double bond, it gives dissimilar products in the two reactions.
When the principal quantum number(n= 3) , the possible values of azimuthal quantum number(l ) is: (1) 0, 1, 2, 3 (2) 0, 1, 2 (3) - 2, - 1, 0, 1, 2
diamond is covalent.yet it has high melting point.why?
What is Dielectric loss These losses occur because of electrons hopping from one lattice site to another in transition metal oxides.
