Dissociation: When sodium chloride (NaCl) dissolves in water, it dissociates into sodium ions (Na+) and chloride ions (Cl-).
Dispersion: Light passing through a prism disperses into different colors due to the varying refractive index of each color - this is known as dispersion.
Ionization: When an electron is removed from a neutral hydrogen atom, it becomes an ionized hydrogen atom (H+).

Is it ionization energy is a periodic property?
Ionization energy generally increases across a period as a result of a higher nuclear charge, however there are some exceptions such as Boron which has a lower ionization energy than Beryllium (because it is in a P orbital), and Oxygen which has a lower ionization energy than nitrogen (Because ionization decreases the electron electron repulsion in its orbitals).
Does selenium have a low first ionization?
Selenium has a moderate first ionization energy, with a value of 941 kJ/mol. This means that it requires some energy to remove the outermost electron from a selenium atom.
The spread of something over a given study area is?
called dispersion, and it describes how a phenomenon or substance is distributed across that specific geographic region. Dispersion can vary in intensity, with some areas showing more concentrated distribution while others exhibit a more scattered pattern. Understanding dispersion is crucial in analyzing the spatial relationships and patterns of the phenomenon in question.
What is an example that illustrates a chemical property?
An example of a chemical property is reactivity, which refers to how a substance undergoes chemical reactions to form new substances. For instance, the ability of iron to rust when exposed to oxygen is a chemical property that showcases its reactivity.
Does a beam of light disperse through a hollow prism?
No, a beam of light does not disperse through a hollow prism because there is no medium present inside to refract or scatter the light. The light would pass through the prism without any change in direction or dispersion.
What are some examples of a colloid in science?
Some examples of colloids in science include milk (emulsion of fat droplets in water), fog (suspended water droplets in air), and whipped cream (dispersion of air bubbles in a liquid).
Are Arrhenius bases an electrolyte?
Yes, Arrhenius bases are electrolytes. When dissolved in water, Arrhenius bases dissociate into ions, allowing them to conduct electricity.
What is the difference between ionization radiation and radiation?
Ionizaton is the process in which molecular compounds dissolve in water. Dissociation is the process in which positive and negative ions of an ionic solid mix with the solvent to form a solution. Hope This Helped!! ~Starcoach25(:
Explain why you would or would not expect significant ionization in the flame?
Ions may not form in a flame because the high temperature typically leads to the dissociation of molecules into atoms. At such high temperatures, most atoms are in the gaseous state, where they are unlikely to form ions. However, in some cases, particularly with metals, ionization can occur due to the presence of high-energy photons or collisions with other particles leading to the formation of ions.
What is represented by H2O H plus plus OH?
The representation H2O H plus plus OH signifies the dissociation of water molecules into hydronium ions (H+) and hydroxide ions (OH-) in aqueous solution. This is the auto-ionization of water where some water molecules act as both acids (donating H+ ions) and bases (accepting H+ ions). The concentration of H+ and OH- ions in pure water is equal at 10^-7 M.
Is H2O l ionization?
The term "H2O l ionization" likely refers to the ionization of water molecules in liquid form. Water molecules can ionize into H+ and OH- ions, creating an equilibrium between H2O, H+, and OH- ions in liquid water. This ionization is a fundamental property of water and is responsible for its ability to conduct electricity to some extent.
An oil film on the surface of water shows continously changing colours?
what phenomenon are their colours dependent on?-scattering, diffraction, interference, dispersion,etc. please also give some other examples from day to day life of these phenomena .
What intermolecular force is CH3I?
CH3I exhibits dipole-dipole interactions due to the presence of a polar covalent bond between carbon and iodine. Additionally, it may also experience some weak dispersion forces.
Does CH3NH2 have London dispersion?
Yes, CH3NH2, also known as methylamine, can exhibit London dispersion forces. London dispersion forces are present in all molecules to some extent, as they are caused by temporary fluctuations in electron density that induce weak attraction between molecules.
What is the separation of a compound into its constituent ions?
This process is known as dissociation. It involves breaking apart a compound into its individual ions, which are positively or negatively charged particles that are formed when the compound dissolves in a solvent. This dissociation allows the ions to move freely in solution and carry out various chemical reactions.
What are the whiskers of a box plot?
They are some measure of the dispersion or range of numbers in the set of data.
Is it ionization energy is a periodic property?
Ionization energy generally increases across a period as a result of a higher nuclear charge, however there are some exceptions such as Boron which has a lower ionization energy than Beryllium (because it is in a P orbital), and Oxygen which has a lower ionization energy than nitrogen (Because ionization decreases the electron electron repulsion in its orbitals).
