When was pantothenic acid isolated?
It was first isolated in the liver in 1933.
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 the number for electrons on hydrogen's first energy level?
Hydrogen's electron configuration is 1s1. It has only one electron. It is located in the first energy level.
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 is energy released on adding an electron to an isolated gas phase atom?
The energy released on adding an electron to an isolated gas phase atom is called electron affinity. It represents the willingness of an atom to accept an additional electron. The process can release energy if the atom's electron affinity is negative, indicating that the atom is stable after gaining an electron.
When was cholera first isolated?
Robert Koch was the person who first isolated cholera in 1883
What year was helium isolated?
It was first isolated in 1895 by William Ramsay.
What was the first virus to be isolated?
The first virus to be isolated and identified was the tobacco mosaic virus in 1892 by Russian scientist Dmitri Ivanovsky.
When was pantothenic acid isolated?
It was first isolated in the liver in 1933.
When was the element neon isolated?
Neon was first isolated in 1898 byWilliam Ramsay & Morris Travers.
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)
When was the H5N1 virus first isolated?
The highly pathogenic H5N1 virus was first isolated in terns in South Africa in 1961, and then in Hong Kong in 1997.
What is a non example of an electron cloud?
A non-example of an electron cloud would be a single isolated electron traveling in a vacuum. In this case, there would be no cloud formation or distribution of multiple electrons around a nucleus.
What is meant by isolated gaseous atom and why this term is used in case of ionization energy?
ionization enthalpy means the energy required to remove an electron from isolated gaseous atom in its ground state . the isolated gaseous state is the state in which no other force of attraction acting on an atom form other atom . so that, we get the exact energy required to romove or add an electron to an atom. and here ground state is used to say that electron are stable and are not exited .. so , the ionization enthalpy is the energy required to remove an electron from gaseous atom which is free from other atom in that state in which electrons are stable. by shashank
Who has the credit of discovering first electron?
J. J. Thompson was given credit for discovering the first electron.
When was fibrinogen first isolated from horse plasma?
Scientists first isolated fibrinogen from horse plasma in 1876. However, the theories about the existence of the protein had been around for decades before.
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.
