When describing atoms and elements, there are three other numbers that may be present in a periodic table: atomic number, mass number, and average atomic mass. Atomic Number The atomic number of an element is equal to the amount of protons that are contained in one atom of that element. ...

63,563,5 gg of copper is one mole of copper or 6,022×10236,022×1023 copper atoms. In fact, if we measure the relative atomic mass of any element on the periodic table, we have one mole of that element. Interactive Exercise 19.1 Question 1 (3291) Adap...
The sum of the number of protons and neutrons in the nucleus is called the mass number of the isotope. Neutral atoms have the same number of electrons as they have protons, so their overall charge is zero. However, as we shall see later, this will not always be the case. Example 1 ...
