What is it called when electrons in the inner energy levels block the attraction between the nucleus and the valence electrons?
nuclear shielding
Why is the ionisation energy of fluorine higher than iodine?
The best modern answer would involve quantum chemistry, but an easier to understand explanation is that the outermost electrons in fluorine are much closer to the nucleus that provides the attraction to hold the electrons and nucleus together as an atom than are the outermost electrons in iodine. This is sometimes called the "screening effect" of inner shell electrons that weakens the attraction between the nucleus and the outer shell electrons in large atoms such as iodine.
What is the energy called that attracts the electrons to the nucleus of an atom?
binding energy The attraction force of the positively charged protons in the nucleus binds (holds secure) the negatively charged electrons near the nucleus.
Why cesium has a lower first ionization energy then rubidium?
Caesium has more electron levels than rubidium, because the electrons are further away the attraction between the outer electrons and protons in the nucleus is less. But that's not just the answer. There is also a thing called electron shielding, the negative charges, of the electrons in the energy levels closer to the nucleus, sort of repel the outer electrons so they can't get closer to the nucleus. Since the electrons are further away and have the attraction from the positively charged nucleus reduced, it takes less energy to break the attraction for caesium than rubidium.
What is electron shielding?
•The shielding effect describes the decrease in attraction between an electron and the nucleus in any atom with more than one electron shell. •It is also referred to as the screening effect or atomic shielding. •Shielding electrons are the electrons in the energy levels between the nucleus and the valence electrons. They are called "shielding" electrons because they "shield" the valence electrons from the force of attraction exerted by the positive charge in the nucleus. Also, it has trends in the Periodic Table
The attraction of the nucleus for the outer electrons in large atoms is lessened as a result of?
Its all called electron shielding.
What causes an electron to jump from Atom to atom?
An electromagnetic force attraction between opposite charges pulls atoms together, either between electrons and nuclei, or as the result of a dipole attraction.
What force of attraction between a positively charged metal ion and the electrons in a metal called?
The Force
When atoms share electrons the electrical attraction of an atom for the shared electrons is called the atoms?
Electronegativity is the attraction of an atom for the shared pairs of electrons.
What is the Layer of electrons outside the nucleus?
the layer of electrons surrounding the nucleus of an atom is called "shells"
What particles might be found in shells around a nucleus?
The particles found in the area surrounding the nucleus are called electrons. Electrons are attracted to the protons in the nucleus, but are repelled from other electrons. This is why they can be found orbiting the nucleus.
What are the electron farthest from the nucleus called?
Electrons farthest from nucleus are valence electrons. They are present in outermost orbit.
