The Atomic Mass will increase. As you go down a group in the Periodic Table the atomic number rises, this increase in the number of protons is accompanied by an increase in the number of neutrons to stabilise the nucleus, and both together lead to an increase in atomic mass.

∙ 8y agoThe trend in atomic mass going down a group is an increase in atomic mass. This is because additional energy levels (shells) and electrons and protons are being added as one moves down a group.

What trend can be observed among the atomic radii of main-group elements down a group?
Within a group, the number of shells (or energy level) increases (as we go from top to bottom of a group) and hence the size of the atom or the atomic radii increases.
What trend is seen atom size going down the periodic table?
Excepting groups 5-12 of the periodic table.the atomic radius increase down in the group.
What trend does electroelectricity follow going down the periodic table?
Electronegativity DECREASES going down a group.
What trend in atomic radius occurs going down on the periodic table and why?
Atomic radii increases moving down a group in the Periodic Table due to the increasing energy levels in the electron configuration and electrons filling in energy levels further away from the nucleus.
Does an element on the periodic table decrease in atomic size when you move across a period from left to right and when you move down a group?
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.
What do you predict the trend in atomic mass will be going down a group?
The atomic mass increases down a group.
What trend can be observed among the atomic radii of main-group elements down a group?
Within a group, the number of shells (or energy level) increases (as we go from top to bottom of a group) and hence the size of the atom or the atomic radii increases.
What is the Group trend Atomic radius?
Atomic radius increases down the group. This is because of the increase in number of shells.
What is the group trend in p-block element?
Atomic radius increases down the group
What is the Atomic polarizability trend?
The Atomic polarizability increases top to bottom i.e down the group and it decreases left to right . This trend is the same as atomic radius .
What trend is seen atom size going down the periodic table?
Excepting groups 5-12 of the periodic table.the atomic radius increase down in the group.
What trend is oberserved among the atomic radii of main-group elements down a group. eplain this trend?
The trend of atomic radius increases down a group on the periodic table. This occurs because each successive element down a group has another energy level. As more electrons are added, more energy levels are needed to hold the electrons.
What is an atomic group?
Each column going down the periodic table is an atomic group.
What general trend in electronegativity do you note going down a group across a period?
going down a group, electronegativity decreases going across a period, electronegativity increases
What is the trend in atomic radius down a group explain?
the atomic radii increases down the group.
What is the periodic trend for elctronegativity?
Going down a group...electronegativity decreases Going across...electronegativity increases
What trend does electroelectricity follow going down the periodic table?
Electronegativity DECREASES going down a group.
