Sodium is in group 1 of the periodic table and each atom includes 11 electrons. A single electron is located in the outer 3s shell, which is capable of holding 2 electrons. Since this is an unstable electron configuration, sodium often loses its outer 3s electron, producing a positively char...
Unstable leptons are leptons that can only exist for a short time and decay quickly. The only lepton that is stable in nature is the electron. Muons... Learn more about this topic: Fundamental Particles of an Atom | List & Types
What is an unstable lepton? How did Ernest Rutherford do the gold foil experiment? What was the Francesco Redi Experiment? What is a quantum qubit? What is a quark in an atom? What subatomic particle did Ernest Rutherford discover?
Protons and neutrons have approximately the same mass. However, one proton is about 1,835 times more massive than an electron. Atoms always have an equal number of protons and electrons, and the number of protons and neutrons is usually the same as well. Adding a proton to an atom makes ...
If an atom absorbs a photon of light with enough energy — say an ultraviolet photon from a hot star— this absorbed energy can cause an electron to transition to a higher energy level for a short time. This is an unstable situation, however, so the electron drops back down and as it ...
Carbon-14 is more unstable than carbon-12, so it's radioactive: it naturally disintegrates, giving off subatomic particles in the process, to turn itself into nitrogen. Carbon-12 and carbon-14 are called isotopes of carbon. An isotope is simply an atom with a different number of neutrons ...

This peculiarity is historically at the root of its success in describing energy quantization, which solved the black body spectrum and also the stability of the hydrogen atom. Nonetheless and paradoxically, quantum mechanics is a linear representation of the world, which hints at it being closely ...

Based on the position and stability of an object, equilibrium can be further categorized into three types: Stable, Unstable, and Neutral Equilibrium. Consider the following figure: Stable, Unstable, and Neutral Equilibrium of Objects Depending on the StabilityDynamic...
