Is it the power of material evidence that wins, not the authority of experts that
kvasek [131]

Yes, it is the power of material evidence that wins.

  • Evidence used to support or refute a scientific theory or hypothesis is known as material evidence.
  • Evidence is also used by scientists in various contexts, such as when they apply ideas to real-world issues.
  • Whether a person accepts the data as proof depends on their presumptions or views regarding how observations relate to a theory.
  • A creative hypothesis is developed by a scientist and may be refuted by testing it against evidence or established truths.
  • Evidence can refute a hypothesis by demonstrating facts that are at odds with it. In contrast, the presence of evidence does not preclude the possibility of future, undiscovered evidence supporting the idea.

Therefore, it is the power of material evidence that wins, not the authority of experts that

proves an answer in Science.

scZoUnD [109]
Leading up to this, calcium gave up 2 valence electrons and thus was denoted as a cation. These 2 electrons were transferred to bromine, which received an overall negative charge because of the addition of 2 valence electrons in its valence shell, and thus formed a negatively charged ion, an anion.

Both formed an ionic bond, due to the electrostatic charge of attraction between the 2 oppositely charged ions. If many ions of Ca and Br are present and numerous ionic bonds have formed it will undergo an arrangement which is that of an ionic lattice, type of structure.
