The periodic table is arranged by atomic weight and valence electrons. These variables allowed Mendeleev to place each element in a certain row (called a period) and column (called a group). The table comprises seven rows and eighteen columns. The number of each row, or period, indicates the...
Groups and Periods:The columns of the periodic table are referred to groups or families, while the rows are called periods. Elements in the same column have similar physical and chemical properties. For example, most of the halogens form anions with a -1 charge....
The elements of Group 17, most reactive of the nonmetals, 7 valence electrons, p-block elements, -1 ions Noble gases The elements of Group 18, unreactive, filled outer energy levels, p-block elements (except He)/8 valence electrons Period Horizontal row of elements in the periodic table ...
The periodic table is where we get to find all the elements and their atomic numbers. If you understand it correctly then chemistry will just be a walk in the p...
Periodic table terms Shape of the table A result of the pattern of electron configuration Group (AKA family) Vertical column on the periodic table Share the same number of valence electrons & often share similar properties Memorize names of 4 families Group 1 – Alkali metals Group 2 – Alkalin...
For the lesson observed the objectives was to explain the trends of the periodic table based on the elements’ valence electrons and atomic numbers. Additionally, students were responsible for applying their previous knowledge in calculating subatomic particles to review the Bohr Models and discus the...
However, there are important differences between the electronic structures of atoms in the progression down any column of the periodic table. These differences are principally due to the fact that as the atomic number increases going down a column, the valence electrons are less tightly bound, and...
