2.  In the Sun

Conductors: Always allow the flow of electric current, and they have a high number of free electrons.
Semiconductors: Allow the flow of electric current only under certain conditions, and they have low no. of free electrons.

Intrinsic Semiconductors are pure and no impurities are added to them.
Extrinsic Semiconductors are impure due to the presence of doping of tetravalent impurities

metals are conductors they conduct electricity
semiconductors conduct electicity partially

Semiconductors - there is a gap of 1eV between the conduction band and the valence band

Intrinsic Semiconductor - does not contain any impurity
Extrinsic Semiconductor - contains impurities]]> 2022-02-01 03:29:17 UTC https://padlet.com/dsonarekha/Bookmarks/wish/2022585300 Ananya Patil Rao - Semiconductors tropicalflower510 https://padlet.com/dsonarekha/Bookmarks/wish/2022587242 Metals have high conductivity and low resistivity. Electrons in valence band overflow into conduction band
Semiconductors have intermediate conductivity and resistivity. At absolute zero, no electron has energy to jump to valence band and hence it behaves as an insulator

But, when an atom loses a certain number of protons or electrons, they become ions. When an atom loses some electrons, the collective positive charges increases, giving it a positive chare, making it a positive ion. When an atom gains some electrons, it gains some negative charges as a whole, giving it a negative charge, making it a negative ion.]]> 2022-02-01 04:20:47 UTC https://padlet.com/dsonarekha/Bookmarks/wish/2022626328 Riya rupeshkumarsingh https://padlet.com/dsonarekha/Bookmarks/wish/2022626332 positive and negative charges ( + , - )]]> 2022-02-01 04:20:47 UTC https://padlet.com/dsonarekha/Bookmarks/wish/2022626332 Aniketh https://padlet.com/dsonarekha/Bookmarks/wish/2022627157 There are two charges, positive - (+) and negative - (-)

these charges are due to the loss or gain of electrons

loss of electrons makes the atom positive while the gain makes it negative]]> 2022-02-01 04:21:50 UTC https://padlet.com/dsonarekha/Bookmarks/wish/2022627157 Mihika https://padlet.com/dsonarekha/Bookmarks/wish/2022627388 Positive and negative charges]]> 2022-02-01 04:22:10 UTC https://padlet.com/dsonarekha/Bookmarks/wish/2022627388 Soham https://padlet.com/dsonarekha/Bookmarks/wish/2022627396 Positive+
