Which electron would be most easily removed from its path around the nucleus?
Wiki User
∙ 14y ago
Nucleus exerts a force on every electron revolving around it. This force is inversely proportional to the distance between the nucleus and the electron. Therefore the electrons in outermost orbit (or shell) have the least nucleic forceacting upon them in comparison to the inner electrons. Therefore they are the most easily removable electrons.
They are called valence electrons.

What particle can be removed from an atom easily?
Electron.
Does high value of electron affinity for an atom means that it will gain electron easily?
Yes, that is part of the definition of electron affinity.
Explain what electric forces between oppositely charged electrons and protons have to do with chemical reactions?
When metals react, they lose electronsto become stable and sometimes form a compound.Now, electrons are negatively charged, and the nucleus, due to the presence of protons, is positively charged.As the atom of the metalgets bigger in size, the valency shell, which holds the valency electron, becomes farther away from the nucleus.The attraction between the valency electron (on the last shell) and the nucleus decreases, so the atom of this type of metal is considered to be reactive as the electron becomes easily lost due to weak forces pulling it towards the nucleus.
Explain why alkali metals are extremely reactive?
This is because they only have on valance electron. This makes it easier to react with other elements and more often also.
Are valence electrons held loosely by the atom?
Assuming you are talking about the electrons in their shells (not the displaced ones):It depends on the distance of those electrons from the nucleus. For example electron in the outer shell of potassium (K) is further away form the nucleus than electron in the outer shell of sodium (Na).It means that potassium can lose this electron in outer shell easier than sodium does, and therefore is more reactive than sodium.
An electron loosely bound to its nucleus is called?
an electron loosely bound to its nucleus is called a free electron.
Why first ionization increases?
First ionization increases because in an atom when we remove first electron of the atom it can be removed easily while as we move to second electron it can't be remove easily because second electron is more near to nucleus and it faces more force of attraction than first one.
What particle can be removed from an atom easily?
Electron.
What is the valance electron of lithium atom that is easily remove to form a lithium with a charge of 1?
the valence electron of lithium that is easily removed is the 1s2 electron
Why is it easier to remove an electron from bromine then it is to remove an electron from fluorine?
The reason why fluorine has a higher ionization energy level than oxygen is because it is closer to the nucleus than is oxygen, therefore, it will take more energy to pull electrons from the nucleus.
Why would an increase in atomic radius make it easier to lose an outer electron?
It's because as atomic radius increases, so do the number of electron shells. The full electron shells closer to the nucleus act like a barrier or shield that reduces the pulling force exerted by the Nucleus on the outer electron. Since the nucleus's pulling force is reduced, an electron on the outer shell can escape much more easily.
Why does valence electron give up outermost energy easily?
The force of attraction between the atom's nucleus and its valence electrons are the least. Hence valence electrons are lost easily.
Choose the element that will most easily lose an electron?
Alkaline Earths will most easily lose an electron. This is because the have a smaller alkali radii than alkali metals causing them to not be as tightly bound to the nucleus. This makes the more readily lose their electrons.
Why 1st ionization energy of Li is lower than that of Hydrogen?
1st ionization energy is the energy to remove one electron from a neutral atom. 2nd ionization energy is the energy to remove an electron from a positively charged ion. When this is done there is a stronger attraction for electrons in the ion than in the neutral atom because there is one less electron to 'interfere' with the electron being removed.
Alkali metals are extremely reactive because?
because they have one valence electron that is easily removed to form a positive ion.
What parts did you identify?
The cell wall, nucleus, vacuoles, mitochondria, endoplasmic reticulum, Golgi apparatus, and ribosomes are easily visible in this transmission electron micrograph.
Is the valence electron farthest or closest to the nucleus?
No. By definition, valence electrons are the furthest electrons from the nucleus in the atom. They are the electrons most easily removed from (or added to) the atom to create ions. A loophole to this answer might be to say that hydrogen and helium only have 1 and 2 electrons respectively so their valence electrons are close. That's a matter of perspective, as no electrons are really "close" to the nucleus to begin with. A typical comparison is to imagine a grape seed in the middle of a football stadium. The grape seed represents the nucleus, and an electron would be a speck of dust on the outside of the stadium.
