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.
Atomic Mass
The atomic weight (not mass) increase from left to right in a period.
The atomic mass increase with 1 unit.
they increase by one going from left to right totally a guess

Atomic Mass
Nothing. They are not correlated
Towards the bottom, atomic mass increases. Atomic number also increases.

The mass does not change much. The Atomic number will increase though.
Stability depends on to proton/neutron ratio; and this ratio increase with the atomic number.
Because atomic mass is the sum of both atomic number and number of neutrons in an atom.
Atomic Mass increases in size as the atomic number increases. For example, hydrogen weighs about 1.01 grams per mole and it has periodic #1. Helium is atomic #2 and it has an atomic mass of 4.00 g/mol. This trend continues all the way to the last known pure element.
The atomic mass of an element is based on the number of nucleons (neutrons + protons) in the atom of the element. It is usually the weighted average of the atomic masses of isotopes of the element, weighted according to the abundance of the isotopes on earth.In most cases, but not all, the atomic mass of an element increase as the atomic number increases.
