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 else can I help you with?
What particle can be removed from an atom easily?
Electrons can be removed easily from an atom because they are the outermost particles and have the least amount of attraction to the nucleus compared to protons and neutrons.
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.
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.
Why the shielding effect of electron makes cation formation easy?
The shielding effect occurs when inner electrons partially block the attractive force between the nucleus and the outermost electrons. In cation formation, this reduced attraction allows the outer electrons to be removed more easily, as they experience less effective nuclear charge. Consequently, the energy required to ionize the atom decreases, facilitating the formation of cations. Thus, the shielding effect enhances the ease of cation formation by weakening the hold of the nucleus on its valence electrons.
Explain why alkali metals are extremely reactive?
Alkali metals are extremely reactive because they have one electron in their outermost energy level, which they readily lose to achieve a stable configuration. This loss of an electron results in the formation of a positively charged ion, making alkali metals highly reactive with substances that can gain an electron easily, such as water and halogens.
What particle can be removed from an atom easily?
Electrons can be removed easily from an atom because they are the outermost particles and have the least amount of attraction to the nucleus compared to protons and neutrons.
How can an electron be easily removed?
An electron can be easily removed by supplying it with enough energy to overcome the attraction of the nucleus, causing it to break free from the atom. This can be achieved through processes such as ionization, where an external source like a photon or electric field interacts with the electron, causing it to be ejected from the atom.
An electron loosely bound to its nucleus is called?
An electron that is loosely bound to its nucleus is called a free electron. These electrons are not tightly held by the nucleus and can be easily influenced by external forces, making them important in conducting electricity in materials.
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 is an core electron?
A core electron is an electron in an atom that is not easily removed or involved in chemical reactions. Core electrons occupy the inner energy levels of an atom and are tightly bound to the nucleus. They play a crucial role in determining the atom's chemical properties.
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 a lithium atom is in the 2s orbital. It is easily removed to form a lithium ion with a charge of +1 because lithium only has one valence electron, making it relatively easy to lose.
Which particle has the greatest chance of overcoming the electrostatic forces surrounding the nucleus of an atom?
An electron has the greatest chance of overcoming the electrostatic forces surrounding the nucleus of an atom. This is because electrons are much lighter and can be easily influenced by external forces, allowing them to move around the nucleus within the electron cloud.
What is the significance of electron configuration when determining the properties of an element?
The electron configuration of an element determines its chemical properties by indicating how its electrons are arranged in energy levels around the nucleus. This arrangement affects how easily an element can form bonds with other elements and participate in chemical reactions.
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.
Alkali metals are extremely reactive because?
because they have one valence electron that is easily removed to form a positive ion.
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.
Electrons of the 19th element?
The 19th element is potassium, which has the atomic symbol K. It has 19 electrons, including one valence electron that can be easily lost.
