Which elements atomic nucleus contains 11 protons?
The nucleus of the atom contains the protons and neutrons. The number of protons, called the "atomic number", determines what kind of element this is. There are almost always more neutrons in the nucleus than protons, except for very light elements. For example, hydrogen has one proton and no neutrons, while helium contains two protons and two neutrons.
Dear Wiki Questioner, The atomic number of an element is defined to be the number of protons its nucleus! Since the most useful characteristics of an element are the result of the number of protons it has, the scientific community chose to order the elements primarily based off of how many protons they contain. So that means that when we are given an atomic number, we automatically are given the number of protons it contains!
o calculate the number of neutrons in an atom, find that atom's atomic number and atomic weight on the Table of Elements. The atomic number is the same as the number of protons in an atom's nucleus. The atomic weight is the same as the total number of protons and neutrons in an atom's nucleus. Subtract the atomic number from the atomic weight to find the number of neutrons. Bromine's atomic number is 35 and…
