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.

How are the elements on a Periodic Tables arranged?
The elements are arranged in the increasing order of their atomic number and repeating properties.
How did mandeleev arranged chemical elements?
Mendeleev arranged elements in his periodic table on the basis of increasing atomic masses.
Are the elements on a periodic table arranged in order of decreasing atomic mass?
No. The elements are arranged in order of increasing atomic number.
The elements are arranged by atomic what?
Number
Are elements in the peridioc table arranged by their physical properties?
no they are not.they are arranged in periods
What increases on the periodic table?
The atomic number increases. The atomic number identifies a particular element and the elements are arranged in increasing order on the periodic table. Also, the atomic weight generally increases as well.
What are the elements from group 2 on the periodic table arranged in order of increasing atomic radius?
The periodic table is arranged in order (across and down the rows) in increasing number of protons in the nucleus; as the number of proton increases the radius of the nucleus generally increases - thus the order is the order reading down group 2: beryllium (least), magnesium, calcium, strontium, barium and radium (largest).
Who arranged the elements into triads?
The scientist who arranged the elements into triads was Dobereiner.
Are the elements of the periodic table arranged by their properties?
Elements are arranged by their atomic number. The properties are periodic when arranged in this manner.
How do elements change going down the periodic table?
Down a group, the atomic number generally increases, size increases, ionization energy decreases, reactivity increases.
How was mendeleev period table arranged?
Mendeleev arranged the elements are arranged in order of increasing atomic masses. He founded that properties of elements are periodic when arranged in this pattern.
What is the trend in the electronegative of the elements from-left to right and from top to bottom?
Electronegativity of the elements generally increases left to right and decreases top to bottom.
How were the elements arranged on his periodic table?
newlands arranged the elements in the periodic table in order of relative atomic massNewlands arranged elements in group of eight like musical notes.
Where are all of the elements arranged?
All the elements discovered till now are properly arranged on the periodic table.
How are the elements on a Periodic Tables arranged?
The elements are arranged in the increasing order of their atomic number and repeating properties.
Are the elements of the periodic table arranged by their neutron?
no, they are arranged by their protons.
Is the reactivity of the metal elements generally increases as you moves from left to right across the periodic table?
No, right to left.
