i. In a multi-electron atom, the positively charged nucleus attracts the negatively charged electrons around it, and there is mutual repulsion between the negatively charged extranuclear electrons. ii. The repulsion by...

i. Effective nuclear charge (Zeff): In multielectron atom, the net nuclear charge actually experienced by an electron is called the effective nuclear charge (Zeff). ii. Screening effect (or shielding effect): In multi-electron...

i. Across a period: As we move across a period, atomic number increases by one and thus, actual nuclear charge (Z) increases by +1 at a time. However, the valence shell remains...

D) Breaking glass
