Why are noble metals difficult to oxidize?
Noble metals are by definition stable and thus in a low energy state. Oxidizing them would put them in a much higher energy state. Nature prefers low energy. That is one reason why water flows down hill. It is flowing to lower energy. So a noble metal is quite happy in that state and is difficult to oxidise. Platinum and gold are two such examples.

Why is it difficult to state exactly what energy is?
Defining energy precisely is difficult because it exists in various forms (kinetic, potential, thermal, etc.) and is the ability to do work or cause change. This versatility and abstract nature make it challenging to capture in a single, comprehensive definition. Additionally, energy has different manifestations across different fields of science, leading to nuanced definitions depending on the context.
Which form of energy is difficult to store?
tidal energy solar energy
What happens when an electron moves from a low energy state to a high energy state?
When an electron moves from a low energy state to a high energy state, it absorbs energy. This absorption of energy causes the electron to jump to a higher energy level or orbit further away from the nucleus. The electron is now in an excited state and can later release this energy in the form of light when it returns to a lower energy state.
Why the first ionization energy decrease greatly from helium to lithium?
It is difficult to remove electron from He than Li. LI easily loses electron and reach stable state.
Which state of energy has the most kinetic energy?
Gaseous State
What is the energy of the highest energy state?
water in a gaseous state
Which is the highest energy state?
The highest energy state is the excited state, where an atom or molecule has absorbed energy and its electrons are at higher energy levels than their ground state. This state is temporary and unstable, as the electrons will eventually return to their ground state and release the absorbed energy.
An atom in its lowest possible energy state is in what state?
The lowest energy state of an atom is known as the ground state. In this state, the electron is in its lowest energy orbital around the nucleus.
An atom is in an excited state when it has its lowest energy?
No, when an atom is in an excited state, its electrons have gained energy, and they proceed to lose it when they fall back into their normal energy levels
What is the lowest allowable energy state of an atom?
The lowest allowable energy state of an atom is called the ground state. In this state, the electron occupies the energy level closest to the nucleus, known as the 1s orbital in the case of hydrogen. The electron has the lowest energy and is most stable in the ground state.
