Answer:
Invasive species, runoff pollution, and climate change.
Explanation:
Invasive species, such as Burmese pythons, threaten the Florida Everglades because they are not native to the natural habitat. Pythons eat the native animals, but they don't have any predators.
Pollution from nearby farms and roads enters the water and damages the ecosystem of the Everglades and Louisiana wetlands. Toxic chemicals lead to detrimental effects for both humans and wildlife.
Humans have drained swampy areas to allow for development. However, this has led to the Everglades drying up and even burning in recent years.
AuI3, or Gold Iodide.
Hope this helps! :)
Protons because each element has a different number. Example, Oxygen has 8, Nitrogen has 7, Carbon has 6, etc.
True. Modern theory of Atom is still using the proposed ideas of Dalton, Thomson and Rutherford.
Explanation:
- Dalton created his atom theory - He said that all matter is made up of atoms and atoms can’t be created nor destroyed or divided into tiny particles. In the same element, all atoms will be identical in size and mass but atoms in the one element will be different in size and mass from the atoms in the other elements. Atoms of different elements combined and forming compounds.
- Thomson found that inferred atoms and negative electrons also contains the negative particles. He also concluded that there was a mass of positively charged material. He explained this with the Raisins Bun model.
- Using Gold Foil Experiment Rutherford found the positively charged nucleus in the centre of every atom. When he was doing this experiment, the positive particles which he passed through the foil got reflected at the centre. This led Rutherford to conclude about the positively charged nucleus at the centre. And he also found about revolving electrons around the nucleus because, in his experiment, some of the positive particles got attracted near the centre.
Neon is an element because it is a pure atom
