PLEASE ANSWER ASAP- In the solid state, how does Water compare to Neon and Argon? Why do you think they act differently?
alekssr [168]
Neon and Argon are known as the noble gases. This means that there inert and don’t typically react. The noble gases have full outer shells and therefore satisfy the octet rule. Hydrogen, on the other hand, must lose an electron to become stable. That is why it reacts.

Recall all the atomic models you described in task 1. Think about the results each model would predict for Rutherford’s gold foi
spin [16.1K]

Bohr's

Explanation:

Experimental evidence of Rutherford best supports the Bohr's model of the atom.

Rutherford performed the gold foil experiment in which he bombarded thin gold foil with alpha particles. He found that most of the particles passed through with just few bouncing back.

With this knowledge, he proposed the nuclear model of the atom. The model suggests that an atom is made up of a positively charge dense center and a large space outside where electrons revolves.

  • The Bohr's model of the atom was based on quantum mechanics proposed by Planck.
  • He assumed the Rutherford's model and suggested that the extranuclear space is made up of electrons in spherical orbits around the nucleus.
