How many atoms in boron
Did you know?
WebBoron is a chemical element with atomic number 5 which means there are 5 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs. WebSolution. Follow the four steps outlines above. Step 1: Find the electron configuration. For Cl atoms, the electron configuration is 3s 2 3p 5. Step 2: Draw the valence orbitals. Ignore the core electrons and focus on the valence electrons only. Step 3: Look for unpaired electrons. There is one unpaired electron.
