Using principles of atomic structure, explain why the atomic radius of Te is less than the ionic radius of Te2− . Photoelectron spectroscopy data for the 1s sublevel of Te and the 1s sublevel of O are represented below. In terms of Coulomb's law and atomic structure, explain why the peak for O is positioned so far to the right of the peak for Te .
Answer:
See explanation
Explanation:
Let us recall that a negative ion is formed by addition of electrons to an atom. When electrons are added to the atom, greater interelectronic repulsion increases the size of the Te^2− hence it is greater in size than Te atom. Therefore, the ionic radius of Te^2− is greater than the atomic radius of Te.
In the second question, oxygen is positioned so far to the right because it has a far smaller nuclear charge compared to Te. Hence in the PES spectrum, the 1s sublevel of oxygen lies far to the right of that of Te.
Using principles of atomic structure, the reason why the atomic radius of Te is less than the ionic radius of Te²− is because of the Electrostatic force of repulsion between the negatively charged electrons of Te²- thereby causing the ion to be bigger than the neutral atom.
We must remember that negative ions are formed as a result of the addition of electrons to an atom.On this note, the electrostatic force of repulsion between the negatively charged electrons of Te²- ion becomes greater. Hence, the Te atomic radius is less than the ionic radius of the Te²- ion.By considering the second scenario, the element oxygen is positioned so far on the right because it has a very much smaller nuclear charge compared to Te.
As a result, in the PES spectrum, the 1s sublevel of oxygen lies far to the right of the 1s sublevel of Te.

What is the value for AG at 100 K if AH = 27 kJ/mol and AS = 0.09 kJ/mol.K)?
O A. AG = 2700 kJ/mol
B. AG = -36 kJ/mol
C. AG = 0 kJ/mol
D. AG = 18 kJ/mol
The value for ΔG = 18 kJ/mol
Further explanationGiven
ΔH = 27 kJ/mol and ΔS = 0.09 kJ/mol.K
T = 100 K
Required
the value for ΔG
Solution
The spontaneous process of a reaction is based on 2 factors :
enthalpy change ΔH decreases and entropy change ΔS increasesΔG=ΔH-T.ΔS

According to the text, which amino acid(s) contains a side chain..
a. in which molecules form covalent disulfide bridges with each other?
b. that is hydrophobic?
c. that forms hydrogen bonds?
d. that is basic?
Answer:
(b) that is hydrophobic
Explanation:
e.g, alanine
Cause, Alanine possess hydrophobic side chain and the most appropriate answer is (d) part......
Alanine is an aliphatic amino acid, because the side-chain connected to the α-carbon atom is a methyl group (-CH3), alanine is the simplest α-amino acid after glycine. The methyl side-chain of alanine is non-reactive and is therefore hardly ever directly involved in protein function..

What happens when molten material travels along the underside of the crust?
Answer:
Explanation:
The earth is comprised of denser materials such as iron and nickel and other siderophile elements in the core and silicate materials in the mantle. The temperature at the core of the earth is extremely high that generates a force, that allows the molten materials (magma) to rise up from the bottom of the mantle towards the crust, in the form of convection currents. This upward movement of magma forces the lithospheric plates to move.
Thus, magma rises from the bottom of the mantle towards the crust.
