FAQs

Does nuclear fission power involve significantly greater risks than most other forms of power generation? ›

The use of nuclear energy for electricity generation can be considered extremely safe. Every year several hundred people die in coal mines to provide this widely used fuel for electricity. There are also significant health and environmental effects arising from fossil fuel use.

Oxidation–reduction (redox) reactions involve the transfer of electrons between chemical species. Oxidation results in the loss of electrons or the increase of the oxidation state by a molecule.

The list of metals arranged by their relative ease of oxidation is called an activity series. Thus, option A is correct. In this context, when we refer to the ease of oxidation, we mean how easily a metal can lose electrons and form positive ions in a chemical reaction.

All nuclear power plants use nuclear fission, and most nuclear power plants use uranium atoms. During nuclear fission, a neutron collides with a uranium atom and splits it, releasing a large amount of energy in the form of heat and radiation. More neutrons are also released when a uranium atom splits.

Which of the following is a major advantage of nuclear-fission-based power plants? The amount of energy per kilogram of fuel is greater than any other fuel source.

When a substance loses hydrogen or gains oxygen, the substance is said to be oxidised. When a substance loses oxygen or gains hydrogen, the substance is said to be reduced.

Oxidation is the loss of electrons by an atom, ion, or molecule. The atom, ion, or molecule that is oxidized will become more positively charged. Oxidation may also involve the addition of oxygen or the loss of hydrogen.

An oxidation reaction strips an electron from an atom in a compound, and the addition of this electron to another compound is a reduction reaction.

In some metals such as steel, the corrosion products formed are very visible and loose. Everyone has observed the red color of iron oxide (rust) seen on improperly protected steel products. The red rust formed is generally scaly and loose and easily falls away exposing more and more basis material to the environment.

The order of some common metals in the electromotive series, starting with the most easily oxidized, is: lithium, potassium, calcium, sodium, magnesium, aluminum, zinc, chromium, iron, cobalt, nickel, lead, hydrogen, copper, mercury, silver, platinum, gold.

What is the easiest element to oxidize? ›

Answer and Explanation: Aluminum is the easiest to oxidize due to its position on the periodic table as it has 3 valence electrons. It will give up electrons easier than the other atoms in order to become more stable.

A chemical reaction that involves the transfer of an electron is classified as an oxidation-reduction reaction. Oxidation is the process of losing an electrons, while reduction is the process of gaining them. Any chemical that causes another chemical to lose electrons (become oxidized) is called an oxidizing agent.

The loss of electrons is oxidation, whereas the gain of electrons is reduction. Consider the charges: when an element gets electrons, its charge is lowered (one acronym to remember the difference is LEO = Lose Electron Oxidation and GER = Gain Electron Reduction).

The process of loss of an electron in known as oxidation and the process of gain of an electron is known as reduction. An oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two species.

The most common reducing agents are metals, for they tend to lose electrons in their reactions with nonmetals.
