Explanation:
its hard to explain unless we know what the question fully asks..
(2) three fewer valence electrons is your answer.
Answer:
d) An atom of arsenic has one more valence electron and more electron shells than an atom of silicon, so the conductivity increases because the arsenic atom loses the electron.
Explanation:
This is an example of a n-type semiconductor. The additional electron introduced to the 'grid' of silicon atoms causes an increase in the conductivity of the silicon. This additional electron is introduced as arsenic loses its extra electron.
Hi there!
A mole is a type of unit measurement for an amount of a substance like in your cast, salt.
One mole of salt will be the equivalent to 58 grams
Hope this helped!~
Answer: it would be cation, 2+
Explanation: electrons are negatively charged by 1. So if you get rid of 2 electrons it would be positive and cation is used to represent positive ions.
