Question

Define shielding and effective nuclear charge. What is the connection between the two?

Answer 1

Answer:

The relation between the shielding and effective nuclear charge is given as

$Z_{eff} = Z -S$

where s denote shielding

z_{eff} denote effective nuclear charge

Z - atomic number

Explanation:

shielding is referred to as the repulsion of an outermost electron to the pull of electron from valence shell.  Higher the electron in valence shell higher will be the shielding effects.  

Effective nuclear charge is the amount of net positive charge that valence electron has.

The relation between the shielding and the effective nuclear charge is given as  

$Z_{eff} = Z -S$

wheres denote shielding

z_{eff} denote effective nuclear charge  

Z - atomic number
