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.
What properties increase down the periodic table?
Atomic Mass
What is the trend from left to right for atomic mass on the periodic table?
The atomic weight (not mass) increase from left to right in a period.
What does adding a neutron to an atom's nucleus do to the atoms mass?
The atomic mass increase with 1 unit.
What trends do you notice about the atomic number and atomic mass as you move left to right across the table?
they increase by one going from left to right totally a guess

Atomic Mass
Ifthe atomic number increase what happens to the atomic mass?
Nothing. They are not correlated
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 is the trend from left to right for atomic mass on the periodic table?
The atomic weight (not mass) increase from left to right in a period.
What does adding a neutron to an atom's nucleus do to the atoms mass?
The atomic mass increase with 1 unit.

How is the atomic mass number of a nucleus changed by alpha decay or by beta decay or by gamma decay?
The mass does not change much. The Atomic number will increase though.
Why the stability decrease with increasing atomic mass?
Stability depends on to proton/neutron ratio; and this ratio increase with the atomic number.
What is the pattern of atomic mass as you go across a period?
As you move across a period in the periodic table from left to right, the atomic mass generally increases. This increase is due to the addition of protons and neutrons in the nucleus of the atoms, which raises the overall mass. However, the increase is not perfectly linear, as isotopes and variations in neutron numbers can cause slight fluctuations in atomic mass values.
Why does the molar mass increase by more than one unit when the atomic number increase by one unit?
Because atomic mass is the sum of both atomic number and number of neutrons in an atom.
Atomic mass trends in the periodic table?
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.
