Dysprosium has an atomic number of 66.
The element is Tin. This can be worked out by simply finding the element with the proton number (or atomic number) of 50. You can double check this by working out the atomic mass number by adding 50 + 66 to give 116. The atomic mass number may not always be the same with elements (as seen with this example) because what you're referring to is an isotope. An isotope is an atom of the same element with the same number of protons but a different number of neutrons. Often 1-4 numbers off its original atomic mass number.
The element with 61 protons is promethium (Pm). It is a rare earth metal that is radioactive and is typically found in nuclear reactors. Promethium is used in luminous paint, atomic batteries, and other specialized applications.
Argon is a gas element. atomic number of it is 18.

The atomic number of an element equals the number of protons in the element.
Dysprosium has atomic number 66 so would normally have 66 electrons.
The symbol for Dysprosium is Dy, and its atomic number is 66.

The atomic number is the number of protons in an atom of an element.
Atomic number = Number of protons
The atomic number of the element with the symbol Be (Beryllium) is 4.
Argon is a gas element. atomic number of it is 18.
Atomic number is the number of protons in the atomic nuclei of the atoms of an element.
The element with the highest atomic number is Oganesson, with the atomic number 118.
An element's atomic number is the # of protons in its nucleus.
The atomic number of an Element refers to it's position in The Periodic Table. The first element (Hydrogen - H) has the atomic number 1. The second element (Helium - He) has the atomic number 2. The fifty-second element (Tellurium - Te) has the atomic number 52. And so on.
