Phosphorus is in group 15 meaning it have 5 valence electrons. This means that it needs 3 more electrons to create a full outer shell. As these three electrons are negatively charged it means that P is a 3- ion (it’s an anion [negatively charged ion])
Answer: 50.806 cm is the correct answer.
Explanation: First divide 6104.5 cm^2 by 22.3 cm.

*Note: When dividing units, subtract the exponents, and when multiplying units simply add the exponents.
Then continue by subtracting 324.55 cm - 273.74 cm.
This should give you an answer of 50.806 cm.

In a positively charged column, Asparate will travel the farthest followed by Threonine, Leucine and Lysine.
Answer:
Hi
The Fermi Level is a term used to describe the set of electron energy levels at a temperature of absolute zero. Fermi's energy concept is important for the understanding of the electrical and thermal properties of solids. Both electrical and thermal processes involve energy values of a small fraction of an electron-volt. In thermal equilibrium, the net current of both electrons and holes is zero.
