Answer:

11 Protons, 12 Neutrons, 11 Electrons.

Explanation:

The number of protons is the same as the atomic number for any element. Since protons and neutrons both weigh about 1amu, if we subtract 11 from 23, we can find the mass of the neutrons which is 12. Since we know that the atom is a neutral atom, there is no charge which tells us that the number of protons and electrons are the same.

What is the most likely result of the pollution of a fresh water resource?
Troyanec [42]

Answer:

Loss of biodiversity in the wetlands.

Explanation: Pollution can be defined as the emission of toxic, poisonous and harmful chemical substances which are capable of causing environmental degradation and contamination.

Nitrogen pollution enters Earth’s freshwater resources from a variety of human activities, including the use of fertilizers and pesticides in agriculture. This nitrogen pollution has a negative effect on plants and animals living in fresh water. Certain wetland plants, however, are able to purify the water and restore it to its non-polluted state.

Hence, what would most likely increase the negative effects of nitrogen pollution is a loss of biodiversity in the wetlands i.e the various species of animal and plants.
