The fact that most alpha particles went straight through the foil is evidence for the atom being mostly empty space. A small number of alpha particles being deflected at large angles suggested that there is a concentration of positive charge in the atom.
Best Answer:<span> </span><span>Bromate ion is BrO₃⁻.
In each hypobromite ion, there are 2 oxygen atom less than bromated ion.
Therefore, hypobromite ion is BrO⁻.
...... The answer is : a. BrO⁻

The answer is; B
Initially, the earth’s atmosphere was mainly filled with carbon dioxide and methane. However, with the evolution of photosynthetic organisms, the composition of the atmosphere changed to be mainly oxygen. This geological time is referred to as the great oxygenation event. The high oxygen levels resulted in oxidation of most the upper lithosphere.
The answer is; B
During this time, the organism on earth began to evolve and live on land. Therefore these geologic events are marked by fossilized of dead primitive organisms such as archaebacteria within the early rocks
