Nuclear power produces more toxic mercury than coal-burning power plants do.

true or false?

True  

Explanation:

Nuclear power plant produces energy by fission or fusion reactions occurring in the nuclear reactor. The energy is harnessed by the heavy metal atom nuclei like uranium. The nuclear power plant produces radioactive wastes.  It does not produce toxic substances and greenhouse gases.

The coal is a fossil fuel, which when burned generates energy in the form of heat. But it also generates pollutant toxic and gases such as carbon dioxide, carbon monoxide, sulfur dioxide, toxic metals elements such as arsenic, mercury and cadmium.  

The quantity and concentration of a mercury released by the nuclear power plant is more than the coal burning plant. Also it is released in the form of radioactive wastes. Thus capable of causing direct hazardous damages such as deadly mutation in the genome. The mercury toxicity by coal power plant will result in gastrointestinal and respiratory diseases.

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.

the answer is the first option

explanation:

just googled it m8. not that hard
