Most often yes, if you're unsure, look on the Periodic Table, the elements electronegativity is usually located labeled, i.e electronegativity of F (the most electronegative element) is 4.0
1. In a period is a trend of decrease from left to right but it is not absolute.2. In a group the atomic radius increase moving down.
The boiling point decrease from lithium to caesium.
Atomic size generally decreases as you move across a period from left to right due to increasing effective nuclear charge. However, atomic size tends to increase as you move down a group due to the addition of more electron shells.
Down a group, the number of shells increases, also the atomic size. Thus , the metallic character increase does increase as going DOWN a group. It is easy to remove an electron froman atom of bigger size.
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.
Alkali metals get softer down Group 1 due to an increase in atomic size and weaker metallic bonding. As you move down the group, the atomic radius increases, leading to a decrease in the strength of metallic bonding and making the metals softer.
Metals tend to increase as you move down a group in the periodic table. This is because the reactivity of metals generally increases as you move down a group due to increased atomic size and lower ionization energy.
In Group 1 (alkali metals), the melting and boiling points decrease as you move down the group due to the increase in atomic size and metallic bonding. In Group 7 (halogens), the melting and boiling points increase as you move down the group due to the increase in atomic size and London dispersion forces.
The p-block elements show a trend in increasing atomic size and decreasing electronegativity as you move down a group. They also exhibit an increase in metallic character and reactivity towards metals, along with a decrease in ionization energy moving down the group.
As we move down a group, electronegativity decreases.
As you move down the groups on the Periodic Table, you generally observe an increase in the number of electron shells, leading to an increase in atomic size. Additionally, there is a trend of increasing reactivity in alkali metals and decreasing reactivity in noble gases as you move down a group. The ionization energy often decreases as you move down a group due to the increase in atomic size and shielding effect.
Yes, shielding increases as you move down a group in the periodic table.
