Berkelium is a member of the actinide and transuranium element series. red = electrons. Be it physics or chemistry, students of elementary science need to be aware of the ways on how to find protons, neutrons, and electrons. How many protons and neutrons does it contain and what is its charge? So if an element has an atomic number of 5, you know that it has 5 protons and 5 electrons. A = 16 + 16 = 32. z = 16 - 18 = -2. 85.4678 atomic mass units. So by definition platinum has 78 protons, so we know that. Electrons are much smaller than neutrons and protons. A cation to be more specific. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. Q. The atom consist of a small but massive nucleus surrounded by a cloud of rapidly moving electrons. Number of Neutrons. Alright, so let's think about this a little bit.
