# Effective Charge on Valence Electrons of Sb

• BugzBunny
In summary, the effective charge experienced by the valence electrons of Sb can be determined using Slater's expression, which includes the nuclear charge (Z) and the number of s and p electrons in the same shell (a), in the shell one deeper (b), and the remaining electrons (c). The electron configuration for Sb is [1s2] [2s2 2p6] [3s2 3p6] [3d10] [4s2 4p6] [4d10] [5s2 5p3], and using the given values, the effective charge is calculated to be 6.3. However, there is ambiguity in the problem's formulation and course

## Homework Statement

Given Slater's expression for effective charge below, determine the effective charge experienced by the valence electrons of Sb.

## Homework Equations

Zeff = Z - 0.35a - 0.85b - c
Where
Z= the nuclear charge; a= the number of s and p electrons in the same shell; b= the number of s and p electrons in the shell one deeper; c= the remaining electrons

## The Attempt at a Solution

I have grouped the electron configuration as such:
[1s2] [2s2 2p6] [3s2 3p6] [3d10] [4s2 4p6] [4d10] [5s2 5p3]

Zeff = 51 - 0.35(4) - 0.85(18) - 28 = 6.3

Is this the correct interpretation? My course notes and the problem's formulation are ambiguous so that the 4d electrons could be construed as a factor of b (× 0.85) or of c (× 1).

## What is the effective charge on valence electrons of Sb?

The effective charge on valence electrons of Sb refers to the net positive charge experienced by the valence electrons of antimony (Sb) in a particular chemical environment. It takes into account the nuclear charge of the atom, the shielding effect of inner electrons, and the effective nuclear charge experienced by the valence electrons.

## How is the effective charge on valence electrons of Sb calculated?

The effective charge on valence electrons of Sb is calculated using the equation Zeff = Z - S, where Z is the nuclear charge (number of protons in the nucleus) and S is the shielding constant, which takes into account the repulsion between the valence electrons and inner electrons.

## What factors affect the effective charge on valence electrons of Sb?

The effective charge on valence electrons of Sb is affected by the nuclear charge (Z), the shielding effect of inner electrons, and the distance between the valence electrons and the nucleus. It may also be influenced by the electron configuration and bonding situation of the atom.

## Why is the effective charge on valence electrons of Sb important?

The effective charge on valence electrons of Sb is important because it determines the chemical and physical properties of the element. It affects the atomic size, ionization energy, and reactivity of antimony, and therefore plays a crucial role in its interactions with other elements and compounds.

## How does the effective charge on valence electrons of Sb compare to other elements?

The effective charge on valence electrons of Sb is similar to other elements in the same group on the periodic table, such as nitrogen, phosphorus, and bismuth. However, it may differ from other elements in the same period due to variations in nuclear charge and shielding effects. It is also dependent on the specific chemical environment of the atom.
