Increases.

When reading the Periodic Table top to bottom, the number of electron energy levels increase. This is because each row in the periodic table corresponds to one electron energy level. The number of energy level corresponds to the period number of the element.

Does the first ionization energy increase or decrease from top to bottom in periodic table for the alkali metal family?
The first ionization energy generally decreases from top to bottom in the alkali metal family. This is due to the increase in atomic size and the shielding effect from inner electrons, which makes it easier to remove the outermost electron.
How does atomic radii increase or decrease in the table?
Atomic radii generally increase from top to bottom within a group (with more electron shells) and decrease from left to right across a period (due to increasing nuclear charge). This trend is influenced by the balance between the increasing positive nuclear charge and the increasing number of electron shells, which can shield the outer electrons from the nucleus.
Why Ionization potential decrease from top to bottom in s block element?
Ionization potential decreases from top to bottom in s-block elements because the atomic size increases, leading to a weaker attraction between the nucleus and the outermost electron. As a result, it becomes easier to remove an electron, requiring less energy, which leads to a decrease in ionization potential.
On the periodic table what are the periods?
Periods on the periodic table are the rows running horizontally from left to right. There are seven periods in total, each indicating the number of electron shells an element's atoms possess. As you move from the top to the bottom of a period, the electron shells increase by one.
Why the atomic radius increase in column of periodic table?
The atomic radius increases down a column in the periodic table because as you move from top to bottom, each element has an additional energy level or shell of electrons. This increase in electron shells results in a larger average distance between the nucleus and the outermost electrons, leading to a larger atomic radius.
Towards the bottom of the periodic table does the atomic mass increase or decrease?
Towards the bottom, atomic mass increases. Atomic number also increases.
Electron affinity tends to what?
Electron affinity tends to increase across a period from left to right on the periodic table, and decrease down a group. This is because elements on the right side of the periodic table have a higher effective nuclear charge, making it easier for them to attract an additional electron.

The first ionization energy generally decreases from top to bottom in the alkali metal family. This is due to the increase in atomic size and the shielding effect from inner electrons, which makes it easier to remove the outermost electron.

Periods on the periodic table are the rows running horizontally from left to right. There are seven periods in total, each indicating the number of electron shells an element's atoms possess. As you move from the top to the bottom of a period, the electron shells increase by one.
What are the acidity and basicity trends of the periodic table?
Acidity tends to increase from left to right across a period and decrease down a group on the periodic table. Basicity follows the opposite trend, increasing down a group and decreasing from left to right across a period.
As elements of group 1 of the periodic table are considered in order from top to bottom ionization of a element decreases this decrease is do to?
The decrease in ionization energy as we move down Group 1 of the periodic table is due to the increase in atomic size. With each successive element, the atomic radius increases, leading to a decrease in the effective nuclear charge experienced by the outermost electrons. As a result, it becomes easier to remove an electron, leading to lower ionization energies.
Which general trends first ionization energy and electronegativity values are demonstrated by group 15 elements as they are considered in order from top to bottom?
Their metallic properties increase and their atomic radii increase.This can be checked with the Reference Table S with the atomic radii and metallic properties. Easy, right?
Why the atomic radius increase in column of periodic table?
The atomic radius increases down a column in the periodic table because as you move from top to bottom, each element has an additional energy level or shell of electrons. This increase in electron shells results in a larger average distance between the nucleus and the outermost electrons, leading to a larger atomic radius.
What happens to the atomic size from the top of the periodic table to the bottom?
The atomic size increase from top to bottom of Periodic Table. As the number of shells increases from top to bottom, the atomic size increases.
What happens to the atomic size from the top to the bottom of the periodic table?
The atomic size increase from top to bottom of periodic table. As the number of shells increases from top to bottom, the atomic size increases.
