Explanation:

Step1: Analyze the question about the periodic table

The problem is about the organization of the periodic table, including identifying groups, periods, and metal/non - metal groups. This falls under the subfield of Chemistry in Natural Science.

Step2: Recall periodic table structure

• Groups: Vertical columns in the periodic table. There are 18 groups (numbered 1 - 18).
• Periods: Horizontal rows in the periodic table. There are 7 periods (numbered 1 - 7).
• Metals and Non - metals: Generally, groups 1, 2, and 3 - 12 are metals (with some exceptions). Groups 13 - 18 contain non - metals, metalloids, and some metals. For example, group 1 (alkali metals), group 2 (alkaline earth metals), and the transition metals (groups 3 - 12) are metals. Groups 17 (halogens) and 18 (noble gases) are non - metals, and groups 13 - 16 have a mix of metals, metalloids, and non - metals.

To label a group and a period: A group is a vertical column. For example, the first vertical column (containing H, Li, Na, K, etc.) is group 1. A period is a horizontal row. The first horizontal row (containing H and He) is period 1.

To number the groups from 1 - 18: Start from the left - most column as group 1 and move right, numbering each vertical column up to group 18.

To number the periods 1 - 7: Start from the top - most row as period 1 and move down, numbering each horizontal row up to period 7.

To identify metals and non - metals: As a general rule, elements on the left side and in the middle of the periodic table (groups 1, 2, 3 - 12) are metals. Elements on the right side (groups 17, 18, and parts of 13 - 16) are non - metals. Metalloids are in between (e.g., B, Si, Ge, As, Sb, Te).

Answer:

For question 4: A group is a vertical column (e.g., the column with Li, Na, K... is group 1), and a period is a horizontal row (e.g., the row with H, He is period 1).
For question 5: Number the vertical columns from left to right as 1, 2, 3, ..., 18.
For question 6: Number the horizontal rows from top to bottom as 1, 2, 3, ..., 7.
For question 7: Groups 1, 2, 3 - 12 are mostly metals; groups 13 - 18 (with exceptions) have non - metals (e.g., group 17 - halogens, group 18 - noble gases are non - metals).
