Can the atomic number of an particular element ever change?
No, the atomic number of an element can't change. Because, we can identify an element by its atomic number and atomic mass. and hence they have been arranged in the periodic table on the basis of their mass number and atomic mass so , it couldn't be changed. Every element has a fixed atomic number..
What element has the atomic number of 168?
The element with the highest atomic number is Ununoctium (total quantity that has ever existed: three atoms), and its atomic number is 118. Thulium has an atomic weight of 168.9342.
What is the atomic notation for Tin-120?
The element with the atomic number 120 is theoretical and hasn't been observed. However, it does still have a systematic IUPAC placeholder name - Unbinilium (Ubn). No attempts have ever been made to create this element. If it were to be discovered, it would fit in under Radium as an Alkaline Earth Metal.
How many electrons do the atoms in the periodic table normally have?
Each element has a specific number that doesn't change. That number is the atomic number they are given on the periodic table. For example Hydrogen has 1 electron, Helium has 2, Lithium has 3, and so on. The number of electrons in a atom would be determined by what ever element it is.
What element has an atomic mass of 120?

Can two atoms of same element ever have different atomic numbers?
The atomic number is identical for all the isotopes of the same chemical element.
Can the number of prontons in an element ever change?
Not unless it becomes another element.
If an element of atomic number 118 is ever synthesized what properties might you expect it to have?
noble halogens

Does the number of protons in mercury ever change?
No it NEVER EVER EVER EVER changes other wise it would be a completely different element like aluminum .

Which element has the highest atomic weight?
I believe the heaviest element known so far is called "Ununoctium," found of course in the bottom right hand side of the period table of elements. It is element 118 and its atomic mass is 294. It is a non-metallic noble gas. However, it is only assumed to be gas. To date, only three atoms of this element have ever been reportedly produced, all from the Joint Institute for Nuclear Research in Russia and the Lawrence Livermore National Laboratory in the USA.
Do the number of protons in a specific atom ever change?
no. because if the number of protons changes, then the element changes
What is the biggest atomic number?
The atom discovered with the highest atom number = number of proton = number of electrons Note that some negative ions might be bigger. The biggest element so far discovered is 294Uuo (Ununoctium, element 118), a superheavy transactinide element. Only a small number of atoms of this element have ever been produced. The caesium atom with an empirical radius of 260 pm.
