Do the number of protons in a specific atom ever change?
no. because if the number of protons changes, then the element changes
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 .
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..
Is calcuim a mixture?
Only of isotopes. Calcium is an element. No mixture of chemicals can ever be a single element. The atoms of any element, such as calcium, always have the same number of protons and the same number of electrons. The number of electrons in an atom is the same as the number of protons in that atom. Different Isotopes of an element have different numbers of neutrons in the nucleus, but this doesn't change any of the chemical properties.
Can the atomic mass of a particular element ever change?
yes
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 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.
Does your id number on your license ever change?
NO
Does the number of protons of carbon ever change?
yes
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.
If an element of atomic number 118 is ever synthesized what properties might you expect it to have?
noble halogens
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.
