How to read the Periodic Table: Copy this on a lined piece of paper, click the mouse for next. How to read the Periodic Table: 5 Atomic Number B Atomic Symbol 10.81 Atomic Mass Boron name This is the number of protons = 5 This is also the number of electrons = 5 (only for neutral atoms) - Atomic Number = 11 - 5 = 6 neutrons NAME: _B,_ Boron ______ Atomic Number: 5 Atomic Mass: 10.81 protons: __5___ neutrons: __6___ electrons: __5___ round off 10.81 to 11 Draw only up to 8 electrons in the second orbital. 3 in this case = 5 total Draw only up to 2 electrons in the first orbital. Draw 6 neutrons as solid circles Draw 5 protons as hollow circles

The outermost orbital is called the valence After you copy this click the mouse for next The outermost orbital is called the valence Up to 18 Up to 8 Only 2 Atoms touch each other at the valence and make chemical bonds.

Draw this map showing the points where each electron Goes into the orbitals. 11 3 7 1 5 6 9 10 13 2 12 4 8
