Atomic mass. Which is the number of protons and neutrons combined.
If magnets are heated to the Curie point, they lose their ability to be magnetic. ... Cooling causes the molecules in the magnet to have less kinetic energy. This means that there is less vibration in the magnet's molecules, allowing the magnetic field they create to be more consistently concentrated in a given direction.
Answer:
1. Proton = electron if the element is not in an ionic state
proton = atomic number
This is not the best way to organize a periodic table because two elements might have similar atomic mass.
<h3>What is periodic table?</h3>
Periodic table is a chart in which arrangement of chemical elements are done.
In the early periodic table elements are arranged on the basis of their atomic masses, while after sometime Moseley arranged the periodic table on the basis of atomic number as he proposed that properties of an element is justified on the basis of number if electrons.
And mass of two substances may be same so it is difficult to differentiate between them.
Hence, two elements might have similar atomic mass.
