The trend of effective nuclear charge down a group in the Periodic Table generally decreases.
What else can I help you with?
Why does the effective nuclear charge decrease as you move down a group in the periodic table?
The effective nuclear charge decreases as you move down a group in the periodic table because the number of electron shells increases, leading to greater shielding of the outer electrons from the positive charge of the nucleus.
How does the effective nuclear charge change as you move down a group in the periodic table?
As you move down a group in the periodic table, the effective nuclear charge generally decreases. This is because the number of energy levels or shells increases, leading to more shielding of the outer electrons from the positive charge of the nucleus.
How does the nuclear charge change as you move down a group in the periodic table?
The nuclear charge decreases as you move down a group in the periodic table.
In going down a group in the periodic table what effect does electron shielding generally have on the effective nuclear charge acting on the outermost electron in an atom?
Electron shielding increases down a group in the periodic table, as more electron shells are added. This reduces the effective nuclear charge experienced by the outermost electron, making it easier for that electron to be removed or participate in chemical reactions.
Why does the effective nuclear charge increase when moving down the first group on the periodic table?
The effective nuclear charge increases when moving down the first group due to the increase in the number of electron shells or energy levels. While the number of protons in the nucleus also increases, the shielding effect from inner electron shells is not sufficient to counterbalance the increased positive charge from the nucleus, resulting in a stronger attraction for the outer electrons.

Does Zeff increase as you move down a group in the periodic table?
Yes, Zeff (effective nuclear charge) generally increases as you move down a group in the periodic table due to the increase in the number of energy levels and electrons, which leads to greater shielding effects.
How does Electronegativity trend across the periodic table?
Electronegativity generally increases from left to right across a period and decreases down a group in the periodic table. This trend occurs because elements on the right side of the periodic table have a greater ability to attract electrons due to increased nuclear charge and effective nuclear charge.
How does atomic radius vary in group and in period on periodic table?
Down a period the atomic radius increases as the number of shells (or energy levels) increases. Across a period the atomic radius decreases as the effective nuclear charge increases.
Would a metal in group 13 in the periodic table be more or less than a metal in group 1?
It would be less reactive because the effective nuclear charge of the alkali-metals is lower than that of group 13. The result is that the valence electron is easier to attract/ionize to form bonds.
What pattern in atomic size occurs in the periodic table?
In the periodic table, the atomic size increases with every period due to addition of an extra shell. The atomic size decreases with every group since no. of electrons and protons are increased with every group across a period leading to extra electrostatic force of attraction between electrons and the nucleus and thus shrinking the size of the atom.
What causes the trend in electronegativity among elements in the periodic table?
The trend in electronegativity among elements in the periodic table is caused by the attraction of an atom for electrons in a chemical bond. Electronegativity increases from left to right across a period and decreases down a group due to changes in atomic size and effective nuclear charge.
What change takes place as you move down in group 17 of periodic table in electron gain enthalpy?
on moving down the group the atomic size as well as nuclear charge inreases.But the effect of increase in atomic size is much more pronounced than that of nuclear charge and thus the additional electrons feels less attraction consequently electron gain enthalpy becomes less negative on going down the group
