Urmmm??????? What is the question
Answer:
The atoms are ranked in decreasing order as follows:
Fluorine ---4
Carbon ----3
Boron ------2
Beryllium --1
Explanation:
Effective nuclear charge (Zeff) is defined as the difference between the actual nuclear charge (the atomic number, Z) and the shielding constant (S).
It is calculated by finding the atomic number and electronic configuration, attributing a shielding value to each electron, adding all the shielding values and using the formula:
Z eff = Z - S
Effective nuclear charges:
An atom of carbon: 3.25
An atom of fluorine: 5.20
An atom of beryllium: 1.95
An atom of boron: 2.60
Answer:
Hover for more information. Phosphine is an example of a polar molecule with non-polar bonds. ... The lone pair of electrons on phosphorus causes the molecule to be asymmetrical with respect to charge distribution and that's why the molecule is polar even though it has non-polar bonds. Its shape is trigonal pyramidal.
