The p sublevel has __three_orbitals that are _dunmbbell_-shaped.
The three orbitals of the p sublevel are oriented in three directions along the x, y and Z axis. The orbitals are called px, py and pz. Each p orbital can have a maximum of 2 electrons. Since there are three p orbitals, the p sublevel can have a maximum of 6 electrons.
1) period 2) the answer is D) I because they are in the same column 3) B)Ge because they are in the same column 4) A) Al because they are in the same column (share same characteristics) 5) D) they have the same number of valence electrons 6) D) nonmetals
The percent of histidine side chains would be deprotonated at pH 7.5 is 5.77 %.
<h3>What is pKa?</h3>
The term pKa refers to the negative logarithm of the acid dissociation constant (Ka). The pH is the negative logarithm of the hydrogen ion concentration.
Hence;
Ka = Antilog (-6) =
[H^+] = Antilog (-7.5) =
We now have to use the formula;
α =
α =
α = 5.77 %
Hence, the percent of histidine side chains would be deprotonated at pH 7.5 is 5.77 %.
