What is the significance of isolated gaseous atom while defining the ionization enthalpy?
An isolated gaseous atom is used as a reference point for defining ionization enthalpy because it represents a system where the electron being removed is not influenced by any external factors. This allows for a precise measurement of the energy required to remove an electron from the atom, known as the ionization enthalpy.

What is meant by isolated gaseous atom and why this term is used in case of ionization energy?
An isolated gaseous atom refers to an atom that is not bonded to any other atoms and is in a gaseous state. This term is used in the context of ionization energy because when an atom is in this state, it requires a specific amount of energy to remove an electron from it, which is known as the ionization energy. The energy needed to remove the electron is a measure of how tightly the electron is bound to the atom.
Who isolated sulfur?
Sulfur was isolated by Antoine Lavoisier and Joseph Gay-Lussac in 1777.
What rocks are copper isolated from?
Copper is primarily isolated from copper ores such as chalcopyrite, bornite, and chalcocite. These ores are typically found in igneous and sedimentary rocks, as well as in hydrothermal veins. Copper can also be found in some metamorphic rocks.
Who discovered phosphorus?
Johann Brandt discovered phosphorus in 1669. He isolated the element from human urine.
Who first isolated fluorine?
Fluorine was first isolated by Henri Moissan in 1886 through the electrolysis of a mixture of potassium fluoride and hydrogen fluoride.

What is electron gen enthalpy?
Electron Gain Enthalpy is the amount of Energy released when an isolated gaseous atom accepts an electron to become a monovalent gaseous anion.For Example:Atom(gas) +Electron ---->Anion(gas) +Energy(Electron Gain Enthalpy)
What is clinical significance of staphylococci isolated from sputum specimens?
Staphylococci isolated from sputum specimens can indicate a possible respiratory infection, particularly if accompanied by clinical symptoms such as cough, fever, and shortness of breath. Further assessment, such as antibiotic susceptibility testing and correlation with clinical findings, is needed to determine the significance and appropriate treatment of the infection.
When was DNA found?
DNA was discovered in 1869 by Friedrich Miescher, a Swiss biochemist, who first isolated it from cells. Its significance in heredity and genetic information was not fully understood until later in the 20th century.
What is first ionization enegy?
The first ionization energy is the energy required to remove the outermost (most loosely held) electron from a neutral atom in its gaseous state. It is a measure of how strongly an atom holds onto its electrons, with higher ionization energies indicating a stronger hold.
What are the significance of the cat on The cat in the rain?
The cat in "Cat in the Rain" symbolizes the main character's desire for a sense of connection and companionship in her lonely, isolated marriage. The cat represents her longing for emotional fulfillment and affection that is lacking in her relationship with her husband.
What does the weather statement isolated tornadoes possible mean?
This means that there is a chance of tornadoes occurring in a few isolated areas. It suggests that tornadoes may form sporadically and not affect a wide area. Residents in the affected areas should stay alert and be prepared to take necessary safety precautions.
What is an adjective for the word isolated?
The adjective for "isolated" is "lonely" or "secluded."

Sentence with the word of isolated?
A sentence with the word isolated. We live in an isolated community in the hills near New Plymouth. The violence in town was just an isolated incident.
Which alkali metal is most reactive with oxygen?
Francium is an alkaline metal, which means that its one electron is easily given away, making it highly reactive. Because the atom is so large, there is a shielding effect between the protons in the nucleus, and the valence electron. This blocks the attractive forces, and the other layers of electrons work to repel the valence electron, decreasing the ionization energy even further. The low ionization energy is what makes francium so reactive, that none of it can be isolated effectively.
How do you make a sentence with isolated?
He was an introvert person so he liked to be isolated. This is a sentence containing the word isolated.
