How many unpaired electrons are present in the ground state of O+ion? Unpaired Electrons: The electrons are filed as per Aufbau's & Pauli's theories; some orbitals consist of single electrons. Such electrons are termed unpaired. These orbitals don't have the 2nd electron with a...
Learn about valence electrons and how to find the number of valence electrons on the periodic table. Discover the role of a valence electron in an atom. Related to this Question How many valence electrons are in the molecule ClO2-?
Step 3 Determine how many electrons the atom has lost or gained. Elements in column 1 of the periodic table (e.g., sodium and potassium) will lose an electron when they react, while elements in the second column (e.g., calcium, magnesium and strontium) will generally lose two electrons...

Analyze the chemical formula and write down the element types that comprise the compound as well as the number of atoms of each type. The first example, KNO3, contains the elements potassium (K—1 atom), nitrogen (N—1 atom) and oxygen (O—3 atoms). The second example, SO42-, contain...
Each electron orbit of the same size or energy (shell) could only hold so many electrons. For example, the first shell could hold two electrons, the second could hold eight electrons, the third could hold 18 electrons, the fourth 32 and so on until reaching the seventh. ...
