Definition of electron affinity?
The energy change that occurs when an electron is added to a neutral atom. This is usually exothermic. Noble Gases are excluded from this. Equation: X(element)+e-(electron)---------> X-1+ energy
Which element in the alkali metals most easily loses electrons and why?
This is francium because having a very lower electronegativity can loss easily an electron.
What conclusion can be drawn from the statement that an element has low electron affinity low electronegativity and a low ionization energy?
The conclusion that can be drawn from an element having low electron affinity, low electronegativity, and low ionization energy is that it is likely to be a metal, particularly an alkali or alkaline earth metal. Such elements tend to easily lose electrons rather than gain them, indicating a preference for forming positive ions rather than participating in covalent bonding. This behavior suggests that they are less reactive in forming compounds and have a weaker attraction for electrons compared to nonmetals.
What are the trends and exceptions to the trends in electron affinity?
Down the group electron affinity decreases Across a period electron affinity increases. However, it should be noted that chlorine is having higher electron affinity than flourine due to the small size of fluorine atom)
What is compound having transfer of electron of a metal element and a non metal element?
buwisit
What is the element that have few valence electron and give them easily?
First of all this is a lot more than just one element. All the alkali metals are like this, all having one valence electron. They are Hydrogen, Lithium, Sodium, Potassium, Rubidium, Cesium, and Francium. Yes they have elements named after countries.
Having an affinity for water?
Hydrophobic means to have an affinity for water.
The term hydrophilic means?
Hydrophilic means loving water, or having a close affinity to it.
What if you add one electron to the element having 9 protons and 10 neutrons?
By adding one electron to an element with 9 protons and 10 neutrons, you would create a negatively charged ion. The electron would occupy an orbital in the electron cloud, resulting in the element being one electron short of achieving a stable electron configuration. This ion would have a charge of -1 due to the extra electron.
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)
If an element is missing one electron... is it a positive ion negative ion different element or different isotope?
If an element is missing one electron, which is defined as having a negative charge, then the element is a positively charged ion. If an element gains an extra electron, it will have a negative charge and be a negative ion. An element with an equal number of positively charged protons and negatively charged electrons is considered to be a neutral element (in other words, no charge). By the way, no charge for this answer!
Why oxygen is having two electron affinity?
First EA is usually exothermic as energy is released when the nucleus attarcts an electron is larger than the energy taken in to overcome their inter-electronic repulsion. Second EA is always endothermic since electron is added to a negative ion. Energy is needed to overcome the repulsion between the two negatively charged species.
