The alkaline earth metals are located in Group 2 of the periodic table, from beryllium (Be) to radium (Ra). They have two electrons in their outermost shell and are the second most reactive after alkali metals.
28 maj 2024 · A group is a vertical (top-to-bottom) column on the periodic table. Each group is given a numerical value, beginning with "1," which is assigned to the left-most column on the periodic table. The group number increases by one for every additional column, up to a maximum of 18.
Give the name and location of specific groups on the periodic table, including alkali metals, alkaline earth metals, noble gases, halogens, and transition metals. Explain the relationship between the chemical behavior of families in the periodic table and their electron configurations.
27 paź 2022 · Beginning at the top left of the table, or period 1, group 1, is a box containing “1; hydrogen; H; nonmetal; gas; and 1.008.”. There is only one other element box in period 1, group 18, which contains “2; helium; H e; nonmetal; gas; and 4.003.”.
Here are the main features of the table: the horizontal rows are called periods. the vertical columns are called groups. elements in the same group are similar to each other. the metals are...
The periodic table is organized into groups (vertical columns), periods (horizontal rows), and families (groups of elements that are similar). Elements in the same group have the same number of valence electrons.
13 gru 2021 · Alkaline-earth metals: The alkaline-earth metals make up Group 2 of the periodic table, from beryllium (Be) through radium (Ra). Each of these elements has two electrons in its outermost...
