Grouping Elements with Similar Chemical Properties Together
Grouping elements with similar chemical properties together
Date: 4.10.2012
Objectives The objective of this experiment is to experimentally investigate which elements show similar chemical properties.
Chemical principle Calcium is a chemical element with symbol Ca and atomic number 20. Calcium is a dull gray, silver solid under standard conditions. Calcium atoms have an electron configuration of (2, 8, 8, 2) and 2 outermost shell electrons. Calcium is in group 2 and period 4 of the periodic table. Calcium commonly forms the cation Ca2+ by donating 2 electrons, reaching a stable electron configuration. Calcium is an alkaline earth metal.
Magnesium is a chemical element with symbol Mg and atomic number 12. Magnesium is a shiny gray solid under standard conditions. Magnesium atoms have an electron configuration of (2, 8, 2) and 2 outermost shell electrons. Magnesium is in group 2 and period 3 of the periodic table. Magnesium commonly forms the cation Mg2+ by donating 2 electrons, reaching a stable electron configuration. Magnesium is an alkaline earth metal.
Copper is a chemical element with symbol Cu and atomic number 29. Copper is red orange metallic luster under standard conditions. Copper atoms have an electron configuration of (2, 8, 18, 1) and 1 outermost electron. Copper commonly forms the cation Cu2+ by donating 2 electrons. Copper is in group 11 and period 4 of the periodic table. Copper is a transition metal.
Calcium and magnesium have the same number of outer shell electrons and similar electron configurations. They are both in group 2 and have similar chemical properties. Copper has a very different number of outer shell electrons and electron configuration from magnesium and calcium. Copper is instead in group 11 and has very different chemical properties compared to magnesium and calcium.
Hydrochloric acid is an acidic compound with the chemical formula HCl. A hydrochloric acid molecule consists of a hydrogen atom H and a chlorine atom
