Draw two electrons in the first energy level and label them with their charge. 4. Draw three electrons in the second energy level and label them with their charge. 5. 9.1095 ×10−28Kg 9.1095 × 10 − 28 K g. Unit electrical charge is 1.6022 ×10−19 1.6022 × 10 − 19 coulomb (C). The nucleus at the center of the atom contains one or more positively charged protons. All atoms of a given element have the same number of protons, which defines the element's atomic number, given the symbol Z Z.

Atomic structure P ast Paper Q uestions Science Exams Sorted 9. An atom of potassium has an atomic number of 19 and a mass number of 39. a. Complete the table to show the number of protons, neutrons and electrons in this. Give a reason for your answer.. Why Atoms Have Atomic Numbers on the Periodic Table. The atoms in each unique element have a specific number of protons. For example, oxygen has two atoms so its atomic number is 2. Iron has twenty-six protons in its nucleus so the atomic number is 26. Scientists can identify an element by its atomic number on the chart. Conclusion The atomic number tells you the number of in one atom of an element. It also tells you the number of in a neutral atom of that element. The atomic number gives the "identity" of an element as well as its location on the periodic table. No two different elements will have the atomic number.
