Answer:
Biodiversity is the variety and variability of life on Earth. Biodiversity is typically a measure of variation at the genetic, species, and ecosystem level.
Explanation:
It should be increasing the rate of the forward reaction will cause a shift to the left because the external stress, which is the increase in rate, will cause the reaction to be unbalanced, and to reach equilibrium it needs to shift to the right.
Each shell contains a fixed number of electrons. The general formula of the number of electrons can be hold in n-th shell is 2n². 5th shell can hold 2x5² = 50 number of electrons.
1st shell contains 2 X 1²= 2 number of electrons, 2nd shell contains 2 X 2²=8 number of electrons, 3rd shell contains 2 X 3²=18 number of electrons, 4th shell contains 2 X 4²=32 number of electrons, 5th shell contains 2 X 5²=50 number of electrons and so on.

Answer:
What led him to change his outlook was because in his experiment, when he fired positively charged alpha particles at a piece of gold foil, he observed that some of the alpha particles were deflected to some degree, and some others bounced back directly toward him.
Explanation:
In his experiment, he fired positively charged alpha particles at a piece of gold foil.
Now, after doing that he observed that some of the alpha particles were deflected to some degree, and some others bounced back directly toward him.
After those observations, he felt that for the order of the alpha particles to have been deflected, they would possibly have been hit or come close to being hit by a positively charged particle in the atom. This made him to conclude that an atom consists mostly of empty space, with a very small and dense but positively charged nucleus at the center. And that this nucleus contains most of the mass of the atom, while the electrons orbit the nucleus.
