Answer:The correct answer is an electron.

Explanation:

Beta decay : In this process, a neutron is converted into a proton and an electron. In this decay, the atomic number is increased by 1 unit.

General representation of beta decay :

_Z^A\textrm{X}\rightarrow _{Z+1}^{A}Y+_{-1}^0e

Where as:

Alpha decay : When a larger nuclei decays into smaller nuclei by releasing alpha particle. In this process, the mass number and atomic number is reduced by 4 and 2 units respectively.

General representation of alpha decay :

_Z^A\textrm{X}\rightarrow _{Z-2}^{A-4}Y+_2^4\alpha

Gamma decay : In this process, the unstable nuclei transformed into stable nuclei by releasing gamma rays. In this process, the mass number remains same.

General representation of gamma decay :

_Z^A\textrm{X}^*\rightarrow _Z^A\textrm{X}+_0^0\gamma.

To be considered a source of water pollution, the source must include a chemical
forsale [732]

To be considered a source of water pollution, the source must include a chemical is false.

<u>Explanation: </u>

The water pollution may be caused either by chemicals or waste materials that doesn’t contain chemicals such as domestic wastes, organic compounds, heavy metals etc. The life on Earth mostly relies on water and air, and if these two gets polluted; the results will be dangerous.

Around 70% of the planet is covered with water and the present state of its purity is a matter of a serious thought. Looking over various pollutants, only chemical wastes are not responsible to pollute the water.

Instead, there is range of elements from plastic scraps to chemical wastes that comes from either the non-point sources or the point sources. There are organic waste materials, heavy metals, volcanic eruptions, Tsunamis, earthquakes, etc. are also responsible to contaminate water and affect the amphibians as well as humans.
