There is a jump in the atomic radius from a noble gas atom to the following alkali metal atom. It contains the elements titanium (Ti), zirconium (Zr), hafnium (Hf) and rutherfordium (Rf). As can be seen in the figures below, the atomic radius increases from top to bottom in a group, and decreases from left to right across a period. They are called “alkaline” earth metals because they form “alkaline” solutions, hydroxides, when they react with water . 102.The increase in atomic radius as one progresses within the alkali metal family from element Z = 3 to Z = 87 in the periodic table can be attributed to * a. the increase in the principal quantum number of the outermost occupied orbital in the atom b. the decrease in the principal quantum number of the outermost occupied orbital in the atom The element which has the largest atomic radius is Cesium. This term “Alkaline” means that the solution has a pH greater than seven and is basic. Example: If the sum of the atomic radii of diatomic carbon is 154 pm and of diatomic chlorine is 198 pm, what is the sum of the atomic radii between a carbon and a chlorine atom. The alkali metals are so called because reaction with water forms alkalies (i.e., strong bases capable of neutralizing acids). Therefore, the additional electron of next alkali metal (one row down on the periodic table) will go into a new outer shell, accounting for the sudden increase in the atomic radius. As can be seen in the figures below, the atomic radius increases from top to bottom in a group, and decreases from left to right across a period. The alkaline earth family is the second most reactive group, and it’s elements can’t be found free in nature. The atomic radius of a chemical element is a measure of the size of its atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding shells of electrons.Since the boundary is not a well-defined physical entity, there are various non-equivalent definitions of atomic radius. So, the new, resulting anion is bigger than its parent atom. Atomic Number :55. Name :Cesium. Therefore, a cation is smaller in size than its parent atom. Why is the first group called alkali metals?
