Like all the group 1 elements, they are very reactive. It is an Actinoid Metal with the symbol Es. Terbium (Tb) is a silvery-gray coloured metal that has the atomic number 65 in the periodic table. It is a Transition metal in Group 11. It has the symbol Er. It has the symbol Mt. Radon (Rn) is a colourless, odourless, radioactive gas non-metal that has the atomic number 86 in the periodic table in Group 18. It has the symbol Pr. Zirconium (Zr) is a gray white metal that has the atomic number 40 in the periodic table. This means that the outer electron is further away from the nucleus so there are weaker forces of attraction between the electron and the nucleus. Lead (Pb) is a soft gray metal that has the atomic number 82 in the periodic table in Group 14. Because of this, they are rarely found in elemental form, and are instead most often found in compounds with other elements.  They react strongly with water to form hydroxides, and directly with oxygen to produce oxides. The Bohr model refers to the treatment of electrons as particles that orbit the nucleus. This family consists of the elements lithium, sodium, potassium, rubidium, cesium, and francium (Li, Na, K, Rb, Cs, and Fr, respectively). Bohrium (Bh) is a radioactive metal that has the atomic number 107 in the periodic table, its appearance is not fully known due to the minuscule amounts produced of it. A cleaned, moistened flame test wire is dipped into a solid sample of the compound and then put into a blue Bunsen flame. It is an Actinoid Metal with the symbol Ac. Palladium (Pd) is a silver-white metal that has the atomic number 46 in the periodic table. Cerium (Ce) is a iron-gray coloured metal that has the atomic number 58 in the periodic table. It has the symbol Sg. Quantum numbers is a term used to describe the assigning of numbers to electrons as a mathematical function to describe their momentum and energy. Although often listed in Group 1 due to its electronic configuration, hydrogen is not technically an alkali metal since it … It has the symbol Lv. Together with hydrogen they constitute group 1, which lies in the s-block of the periodic table. Hydrogen atoms under a lot of heat and pressure are forced together to make a larger atom of helium. The alkaline earth metals or simply alkaline earths are recognized as an important group and family of elements. It is located in Group 13 of the periodic table. The flame colour indicates which alkali metal ion is present in the compound. Elements of the group have one s-electron in the outer electron shell. Vibrational modes is a term used to describe the constant motion in a molecule. A trough is the lowest point on a transverse wave. Antimony (Sb) is a hard brittle silver-white semi metal that has the atomic number 51 in the periodic table. It has the symbol Bi. The group 1 elements in the periodic table are known as the alkali metals. They include lithium, sodium and potassium, which all react vigorously with water to produce an alkaline solution. It is an Actinoid Metal with the symbol Np. It is a Transition metal in Group 9. Group 1 is so-called because each of the elements has a single outer electron. It is an Alkali Metal with the symbol Fr and is located in Group 1 of the periodic table. It has the symbol Og. The members of this group 1 are as follows: 1. The Group 1 elements are: Hydrogen. It has the symbol Fl. It is therefore possible to predict that the melting point of rubidium is between 29°C and 63°C (it is actually 39°C). Alkali metals are so reactive due to their electronic configuration - they have one valence electron and a large atomic radius. They are called s-block elements because their highest energy electrons appear in the s subshell. The group 1 elements are placed in the vertical column on the left hand side of the periodic table. It is a Lanthanide metal. It is an Actinoid Metal with the symbol Am. The reactivity of the alkali metals increases down the group. Group 1 contains elements placed in a vertical column on the far left of the periodic table. Curium (Cm) is a silvery-white colored radioactive metal that has the atomic number 96 in the periodic table. Elements of Group 1 of the periodic table W. Tantalum ( Ta ) is a coloured.
