In terms of atomic structure, explain why the electron affinity of fluorine is lower than aluminum. How does the atomic radius of F- compare to the atomic radius of neon? Explain. Why, in terms of atomic structure, is the radius of a Na atom larger than the r...
In terms of atomic structure, explain why the ionization energy is not the same between the strontium ion and bromide ion even though they are isoelectronic. What is ionization energy and how is it determined? The first five successive ionisa...
NCERT solutions for CBSE and other state boards is a key requirement for students. Doubtnut helps with homework, doubts and solutions to all the questions. It has helped students get under AIR 100 in NEET & IIT JEE. Get PDF and video solutions of IIT-JEE Mains & Advanced previous year pap...
Seeing that picture would have delighted Rutherford, Thomson, and the other pioneers of atomic science. Now, scientists are even starting to see inside atoms. Thanks to the development of really powerful electron microscopes, we can peer deep inside things at their internal atomic structure. In ...
A computer turns this information into a map of the specimen that shows up its detailed atomic structure. One big drawback of ordinary electron microscopes is that they produce amazing detail using high-energy beams of electrons, which tend to damage the objects they're imaging. STMs avoid ...
Hin and his colleagues measured the abundances of two isotopes of magnesium — Mg-24 and Mg-25 — in a variety of chondrites, Earth rocks and Mars meteorites. Isotopes are versions of an element that differ in the number of neutrons in their atomic nuclei; Mg-25 has one more neutron tha...
There are many theories of what the “Dark Energy” is, and the IKBFU scientists presented their own theory. “The so-called Casimir effect (named after the Dutch physicist Hendrik Casimir), which consists in the fact that two metal plates placed in a vacuum are attracted to each other, ...
(PPA) α-amylases are summarized in Fig.2in terms of average reaction free energy profiles, each from ~300 independent simulations at 25 °C. It can immediately be seen that the two enzymes lower the activation barrier by ~10 kcal mol−1compared with the reference reaction in ...
It might be caused by the loose structure of FAs increased the dissociation between FA molecules after depletion of vinculin. Presenting results that support the amount of vinculin is essential for FA formation and stabilization. FA molecules binding to F-actin is critical in recruitment of actin ...
In terms of structure and bonding explain why water is a liquid and hydrogen sulfide is a gas at room temperature?Temperature and Pressure Standards:Room temperature is a standard temperature used in chemistry and is equal to 25 Celsius degrees. It is ...
