| Definition | The stable isotope of oxygen with relative atomic mass 17.999160 and 0 Why is the atomic number important? The number of protons in an atom is called its atomic number. This number is very important because it is unique for atoms of a given element. All atoms of an element have the same number of protons, and every element has a different number of protons in its atoms. Why is atomic number more important than atomic mass? Atomic number is Number of electrons in an atom. Now, Most of the chemical properties depend upon its valency electrons and Electronic configuration.So, atomic number is more important to a chemist, than its relative atomic mass. Why is it important to know the atomic symbol atomic number mass number and charge?The number of electrons determines the electron configuration of the atom. The atomic number tells us important information: The number of protons, the positive charge, the number of electrons the negative charge, and the typical behavior of the element based on the electron configuration. How do you write a complete atomic symbol?To write a complete nuclear symbol, the mass number is placed at the upper left (superscript) of the chemical symbol and the atomic number is placed at the lower left (subscript) of the symbol. What is the symbol of an electron? Electron
