Why the stability decrease with increasing atomic mass?
Stability depends on to proton/neutron ratio; and this ratio increase with the atomic number.
What ordered pairs of elements shows an increase in atomic number but a decrease in average atomic mass?
this happens with argon and potassium, and also with cobalt nickel. fun stuff.
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 the mass increase or decrease when anhydrous compounds decompose?
when anhydrous compounds decompose their mass will decrease
What properties increase down the periodic table?
Atomic Mass
Towards the bottom of the periodic table does the atomic mass increase or decrease?
Towards the bottom, atomic mass increases. Atomic number also increases.
Do you increase or decrease in mass?
you increase or decrease mass by taking the mass out
Why the stability decrease with increasing atomic mass?
Stability depends on to proton/neutron ratio; and this ratio increase with the atomic number.
What causes density to decrease?
an increase in volume and/or a decrease in mass
What ordered pairs of elements shows an increase in atomic number but a decrease in average atomic mass?
this happens with argon and potassium, and also with cobalt nickel. fun stuff.
What accompanies an increase in atomic number within a specific period?
An increase in atomic number would be accompanied by a decrease in radius, and an increase in electronegativity.
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 the mass increase or decrease when anhydrous compounds decompose?
when anhydrous compounds decompose their mass will decrease
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.
Does gravity increase or decrease with mass of an object?
Gravity increases with mass.
How do you increase the frequency in an oscillating mass-spring system?
You either Decrease mass or increase spring force.
What properties increase down the periodic table?
Atomic Mass
