What is the atomic number for pd?
Palladium is a d block metal element. atomic number of it is 46.
There are no known stable isotopes of the element with an atomic number of a 56 B 38 C100 D 20?
The element with an atomic number of 100 is Fermium (Fm), which does not have any stable isotopes. Fermium is a synthetic element that is produced in nuclear reactors and has only radioactive isotopes. Stable isotopes have a balance of protons and neutrons that result in a nucleus that does not undergo radioactive decay.

Wha do each of the numbers in a box represent on the periodic table?
The number at the top of the box is the atomic number, which represents the number of protons in the nucleus of an atom. The number at the bottom of the box is the atomic mass, which is the weighted average mass of an atom of that element based on the relative abundance of its isotopes.
What changes in atomic number and mass number occur in beta emission?
Electron (beta minus) decay: the atomic mass remain approx. constant, the atomic number will be greater with 1 Positron (beta plus) and electron capture decay: the atomic mass remain approx. constant, the atomic number decrease with 1 Double beta decay: the atomic mass remain approx. constant, the atomic number will be greater with 2

What does the atomic number tells you about the element?
It tells you (1) how many protons are in the element, and (2) what the element is since all atoms of an element will have the same number of protons.It's D. The number of protons in its atoms.It tells how many protons/electrons that element has.
