Solution
The given text appears to be a table showing atomic names and symbols. It is organized in groups and periods, with different elements represented by their respective symbols. The elements are arranged in increasing atomic number from left to right and top to bottom.
To read the table, you can start by identifying the group numbers (1A, 2A, 3A, etc.) and period numbers (1, 2, 3, etc.). The group numbers represent the number of valence electrons in the elements of that group, while the period numbers indicate the energy level or shell in which the elements are located.
For example, in group 1A, we have hydrogen (H) and helium (He). In group 2A, we have lithium (Li) and beryllium (Be). Moving down to period 2, we have boron (B), carbon (C), nitrogen (N), oxygen (O), fluorine (F), and neon (Ne).
Continuing this pattern, you can identify the elements in each group and period by their symbols. For instance, in group 3A and period 3, we have sodium (Na) and magnesium (Mg). In group 4A and period 4, we have aluminum (Al) and silicon (Si).
You can follow this process to identify the names and symbols of the elements in the rest of the table.
