When an atom emits a 1 beta particle what can be said about is mass number and atomic number?
Emiting a beta particle is the result of a neutron changing into a proton so the atomic number increases by 1 and the mass number stays the same
When the elements on the periodic table are arranged by increasung atomic number the atomic mass generally increases as the atomic number increases. for some elements however the atomic mass of the el?
It is difficult to be sure what the question is about because it has been truncated.However, it is true that the atomic mass (or standard atomic weights) increases with atomin number. There are, of course, isotopes of elements with a low atomic number which are heavier than atoms of higher atomic number. But there are some examples where the average mass is not in the expected sequence.
What happens to the atomic number as you move across a period?
.The atomic mass increases
What is the new element formed after the alpha decay occurred?
AlphaThe atomic number goes down by two and the atomic mass number goes down by four.Beta-The atomic number goes up by one and the atomic mass number stays the same.Beta+The atomic number goes down by one and the atomic mass number stays the same.
What happens to the atomic mass number as you move across the periodic table?
the atomic mass in the periodic table increases as you go from left to right across a row.....
Does The atomic number increases but the atomic mass stays the same in a gamma ray?
yes!!

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 atomic mass number of an isotope?
it depends because isotopes have different nucleon numbers but their atomic number stays the same.
Atomic mass is an atoms number of what?
it depends because isotopes have different nucleon numbers but their atomic number stays the same.
What trends do you notice about the atomic number and atomic mass as you move left to right across the periodic table?
The atomic number increases from left to right. The atomic number also increases.However, there are few exceptions for atomic mass.
Why does an atomic number increase?
If you mean looking at the next element on the table then the mass would increase. However, the atomic number is only the number of protons in an atom and is not a true indicator of atomic weight. Variations in Neutron count can cause differences in atomic weights.
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
