What else can I help you with?
How come it is that outer shell electrons participate in bonding and not the electrons that in other shells?
Inner shells of electrons are always full and cannot accept any additional electrons. Also, they can not generally lose electrons because the energy require to remove an electron from an inner shell is generally too high to be achieved in a chemical reaction.
Why are cation always smaller than the atoms from which they are formed?
Cations are positive ions formed by the loss of electrons. As cations have less number of electrons, the effective nuclear charge increases and as such,the remaining electrons are more tightly bound by the nucleus and there is a reduction in size. In most of the cases, the parent atom loses all the valence electrons in order to form a cation leading to the reduction of one shell(the valence shell).
What substance is more active Cu or Fe?
Yes iron is more reactive than copper because it is higher up on the activity series. There is more reasons to back this up such as outer electrons more tightly bound than others. Those who have less tightly bound electrons are more reactive. Hope this helps you. :D
How many number of electrons to fill the outer shell of carbon?
Carbon has four valence electrons, so it will need four more electrons to fill its outer shell.
What electrons are scattered in the most empty space around?
Electrons in the outermost shell (valence electrons) of an atom are the ones that are most likely to be scattered in the most empty space around the nucleus. This is because these electrons have higher energy levels and are further away from the nucleus, making them more loosely bound and more easily scattered.
Why are valence electrons used in bonding?
The valence electrons in the otermost shell of an atom are from an energy point of view the easiest to rmove or share with other atoms. The inner sheel alectrons are much more tightly bound. The important measure of this energy is the ionization energy.
What is an inner shell electron?
These are the electrons that are not the valence electrons and are also known as core electrons.See the Related Questions and Web Links to the left for more information about valence and core electrons.
Do conductors have more electrons than an insulator?
No, conductors do not have more electrons than insulators. In fact, conductors have loosely held electrons that are free to move, allowing the flow of electric current, while insulators have tightly bound electrons that do not flow easily.
An electron in an atom's outer shell is shielded from the nucleus by what?
An electron in an atom's outer shell is shielded from the nucleus by inner-shell electrons. These inner-shell electrons repel the outer electron, reducing the net attractive force from the nucleus. This shielding effect helps explain why outer-shell electrons are more loosely bound and easier to remove during chemical reactions.
How come it is that outer shell electrons participate in bonding and not the electrons that in other shells?
Inner shells of electrons are always full and cannot accept any additional electrons. Also, they can not generally lose electrons because the energy require to remove an electron from an inner shell is generally too high to be achieved in a chemical reaction.
Electrons farther from the nucleus are said to be of?
Electrons farther from the nucleus are said to be of higher energy levels or higher orbitals. This means they have more energy and are less tightly bound to the nucleus compared to electrons closer to the nucleus.
Why are cation always smaller than the atoms from which they are formed?
Cations are positive ions formed by the loss of electrons. As cations have less number of electrons, the effective nuclear charge increases and as such,the remaining electrons are more tightly bound by the nucleus and there is a reduction in size.

Why can't electricity pass through an insulator?
Insulators have tightly bound electrons that do not move freely. This prevents the flow of electric current since current is the movement of electrons. Unlike conductors that allow electrons to move easily, insulators block the flow of electricity.
What is valence shell of electrons?
Valence shell is outermost shell of an atom.It cannot hold more than 8 electrons.
How does the energy of core electrons compare with the energy of valence electrons?
The energy of the valence electrons is greater than the energy of the core electrons.
How many number of electrons to fill the outer shell of carbon?
Carbon has four valence electrons, so it will need four more electrons to fill its outer shell.
