No, the Atomic Mass generally increases as you move down a group in the Periodic Table. This is because each successive element has more protons and neutrons, leading to a higher atomic mass. While there may be exceptions due to isotopes or specific elements, the overall trend is an increase in atomic mass down a group.
What else can I help you with?
What properties increase down the periodic table?
Atomic Mass
What is the trend in atomic mass going down a group?
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.
Does atomic mass increase or decrease?
Atomic mass generally increases as you move down a group in the periodic table due to the addition of more protons and neutrons in the atomic nucleus. However, within a period, atomic mass typically increases from left to right as more protons and neutrons are added. Exceptions can occur due to isotopes, which may have varying atomic masses. Overall, atomic mass trends upward with increasing atomic number.
What happens to the atomic mass as you go from down a group in the periodic table and why?
The atomic mass generally increases as you go down a group in the periodic table. This is because as you move down a group, the number of protons and neutrons in the nucleus of the atoms increase with the addition of more energy levels or electron shells.
Why does the density of group 2 metals increase?
The density of group 2 metals increases as you go up the group. This is because atomic radius decreases as you go up the group. Density is mass / volume and the ratio of mass to volume of atoms of the elements goes up with the decrease in radius.
What do you predict the trend in atomic mass will be going down a group?
The atomic mass increases down a group.
What properties increase down the periodic table?
Atomic Mass
What happens to the group 1 elements as you go down the table?
As you go down Group 1 in the periodic table, the reactivity of the elements increases due to the decrease in ionization energy and increase in atomic size. The metals become more reactive with water and air as you move down the group.

Why does the density of group 2 metals increase?
The density of group 2 metals increases as you go up the group. This is because atomic radius decreases as you go up the group. Density is mass / volume and the ratio of mass to volume of atoms of the elements goes up with the decrease in radius.
What is the metal in group 14 with the lowest atomic mass?
The metal in group 14 with the lowest atomic mass is tin (Sn), which has an atomic mass of approximately 118.71 atomic mass units.
Towards the bottom of the periodic table does the atomic mass increase or decrease?
Towards the bottom, atomic mass increases. Atomic number also increases.
What change in atomic number occurs when a nucleus emits an alpha particles?
An alpha particle has 2 protons and 2 neutrons. This would make the atomic number decrease by 2 and the Atomic Mass will decrease by 4.
How do the sizes of atoms vary within a group (family)and explain why?
The atomic radius increase down in a group; the cause is the lower attraction from the nucleus atoms with increased bigger atomic mass.
What property increases going down a group in periodic table?
Atomic size increases going down a group in the periodic table. This is because additional energy levels are being filled with electrons, leading to an increase in distance between the nucleus and the outermost electron shell.
