Atoms of arsenic (As) are often added to silicon (Si) in a process called doping to change the conductivity of the silicon. How

IRINA_888 [86]

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.

The melting point of the metal potassium is 63.5c, while that of titanium is 1660c. what explanation can be given for this great

kiruha [24]

The melting point of potassium = $63.5^{0}C$

Melting point of titanium = $1660^{0}C$

Titanium has a stronger metallic bonding compared to potassium. Titanium being a transition metal has greater number of valence electrons (4 valence electrons) contributing to the valence electron sea compared to potassium which has only one valence electron. The atomic size of Titanium much lower than that of potassium, so the bonding between Titanium atoms is stronger than that of potassium. Hence, the melting point of Titanium is much higher than that of potassium.
