Answer:
The correct answer is option C
Explanation:
According to Heisenberg's principle "At the instant of time when the position is determined, that is, at the instant when the photon is scattered by the electron, the electron undergoes a discontinuous change in momentum. This change is the greater the smaller the wavelength of the light employed, i.e., the more exact the determination of the position. At the instant at which the position of the electron is known, its momentum therefore can be known only up to magnitudes which correspond to that discontinuous change; thus, the more precisely the position is determined, the less precisely the momentum is known".
Hence, this principle made scientists to realize that electrons could not be located in defined orbits which a contradictory of Bohr's model.
Answer:

Answer:
each element is designated by its <u>Chemical Symbol </u>which is usually from the first letters of the elements name
Explanation:
It would be C) atoms of the opposite charges. iconic bonds are formed by the attraction of two atoms of the opposite charge.
Hope this helps :)
can you please make this the brainiest answer it would really help me. thank you :)
The three factors determine the chemical properties of an element:
<span><span>The number and arrangement of electrons in an atom
</span><span>The number of valence electrons
