The group of the element (on the periodic table) tells you how many electrons there are in the atom's outer shell. From this information, you can figure out how many electrons it needs to gain or lose to achieve a full outer shell. Groups 1-3 (metals) will LOSE electrons. Groups 5-7 (non-metals) will GAIN electrons.

MOLES & STOICHIOMETRY (iGCSE) Fahad H. Stoichiometry is the quantitative relationship between the amount of reactants used and the amount of products formed. It is based on the law of conservation of mass. The law states that matter is neither created nor destroyed in a chemical reaction. Meaning that the mass of the reactants MUST equal the mass of the products.The mole, symbol mol, is the SI unit of amount of substance. One mole of a substance contains the same number of the stated particles, atoms, molecules, or ions as one mole of any other substance. One mole contains 6.02 x 1023 particles (e.g. atoms, ions, molecules); this number is known as the Avogadro Constant. For example: tesoro mio restaurant vancouver Aug 08, 2015 · 3.

The group of the element (on the periodic table) tells you how many electrons there are in the atom's outer shell. From this information, you can figure out how many electrons it needs to gain or lose to achieve a full outer shell. Groups 1-3 (metals) will LOSE electrons.
