Question

Why was a change in the bohr model of atom required? Due to which important development (s), concept of movement of an electron in an orbit was replaced by, the concept of probability of finding electron in an orbital? What is the name given to the changed model of atom?

Answer 1

The 1s orbital is spherically symmetrical, so the probability of finding a 1s electron at any given point depends only on its distance from the nucleus. The probability density is greatest at r = 0 (at the nucleus) and decreases steadily with increasing distance

Answer 2

Answer:

The solubility in the aqueous phase increases much more with temperature, as the solubility in the hydrophobic phase does.
