∙ 11y ago
Valence electrons are electrons on the outermost shell/orbitals. Sheilding electrons are inner electrons that block valence electrons from protons causing less attraction.

What does electron shielding most affects?
Electron shielding primarily affects the effective nuclear charge experienced by valence electrons in an atom. It reduces the attraction between the valence electrons and the nucleus, leading to a decrease in the ionization energy and atomic size of the atom. Additionally, electron shielding can influence the chemical reactivity of an element by affecting the ease with which valence electrons can participate in bonding.
What is the difference between potassium and aluminum?
potassium belongs to group 1 and has one valence electron. aluminium belongs to group 13 and has three valence electrons.
What is the difference between the Lewis model and the valence-shell electron pair repulsion (VSEPR) model?
VSEPR only shows the geometric shape of the element
What is the definition of VESPR Theory?
VSEPR theory stands for Valence Shell Electron Pair Repulsion theory. It is a model used to predict the geometry of molecules based on minimizing the repulsion between electron pairs in the valence shell of an atom. By considering the repulsions between electron pairs, VSEPR theory helps determine the shape of molecules.
How many valence electrons are in alkali metals?
Alkali metals have 1 valence electron.

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
What is the difference between a electron and a valence electron?
While electrons can be on any layer, a valence electron is an electron that is found in the outermost layer of an atom and that determines the atom's chemical properties.
What is the difference between potassium and aluminum?
potassium belongs to group 1 and has one valence electron. aluminium belongs to group 13 and has three valence electrons.
What is it called when electrons in the inner energy levels block the attraction between the nucleus and the valence electrons?
It is called shielding or screening effect. Inner electrons shield the valence electrons from the positive charge of the nucleus, reducing the attractive force between them.
Calculate Z eff for a valence electron in an oxygen atom?
The effective nuclear charge (Z_eff) experienced by a valence electron in an oxygen atom can be calculated by considering the number of protons in the nucleus minus the number of core electrons shielding the valence electron. For oxygen with 8 protons and 2 core electrons in the 1s orbital, the Z_eff for a valence electron in the 2s or 2p orbital would be approximately 6 (Z_eff = 8 - 2).
What factors affect an atoms electronegativity?
The main factors that affect an atom's electronegativity are its nuclear charge (more protons result in stronger electronegativity), the distance between the nucleus and valence electrons (closer electrons experience stronger attraction), and the shielding effect of inner electron shells (more shielding reduces electronegativity).
What is the difference between the Lewis model and the valence-shell electron pair repulsion (VSEPR) model?
VSEPR only shows the geometric shape of the element
What is the functions of valence electron?
Valence electrons are the ones that are used in bonding between atoms.love
What is the effective nuclear charge experienced by calcium's valence electrons?
The effective nuclear charge experienced by calcium's valence electrons is approximately +2, since calcium has 20 protons in its nucleus and 18 core electrons shielding the valence electrons from the full nuclear charge.
An electron in the outermost energy level of an atom is a?
valence electron, which is involved in the atom's chemical reactions and determines its chemical properties.
What is the number of valence electrons for Li and K?
Li has 1 valence electron, while K has 1 valence electron.
