No. Very few theories are completely accepted or rejected; most theories go through several iterations of modification and adjustment. Even the most ridiculous theory has at least SOME element of validity, and the best theories aren't 100% perfect.
The basic element of physics is energy. Energy is the ability to do work or produce change in a system. It is a fundamental concept that underlies many principles and theories in physics.
yes, because this barriers are essential in communicating, it is an obstacles in communication concerning language of people involved, the environment and those of immediate situation can obstruct the flow of meaning and cause communication breakdown.
Fact supported theories and not guesses, but reliable accounts of the real world. Most theories accepted by scientists have been repeatedly tested by experiments and thus can be used to make predictions, which are then most likely to be true
No, because the phrase "endangered element" is nonsense.

Do you mean "What element # is nitrogen?" because the answer to that is 7.
According to Google, that element is called :Einsteinium (Es, 99) - Albert Einstein.
