1. A 1s electron in a B atom has a smaller sized Zeff than a 1s electron in a Be atom.

You are watching: Classify each statement about effective nuclear charge

Zeff = Z – S

the 1s electron will have actually the very same shielding constant (S) to one more 1s electron

Z of B = 5Z of Be = 4Zeff of B > Zeff of Be

Statement → FALSE

2. Effective nuclear charge does not depend on the variety of electrons current in an atom.

Zeff = Z – S

the complete shielding (S) an electron feels depends on its area and also the variety of electrons prior to it

Statement → FALSE

3. Across a duration, as Zeff increases, atomic dimension increases.

Problem Details

Classify each statement around effective nuclear charge, Zeff, as true or false.

1. A 1s electron in a B atom has actually a smaller Zeff than a 1s electron in a Be atom.

2. Effective nuclear charge does not depfinish on the variety of electrons present in an atom.

3. Across a period, as Zeff rises, atomic size boosts.

4. Effective nuclear charge rises from left to right throughout a period on the regular table.

5. In a Be atom, 1s electron has a greater Zeff than a 2s electron.

6. Electrons in an s orbital are more reliable than those in various other orbitals at shielding various other elctrons from nuclear charge.
