Answer :
Final answer:
Option 1.
Most of the groups in the Periodic Table of the Elements contain metals and metalloids. The Periodic Table categorizes elements into metals, nonmetals, and metalloids based on their properties, with metals on the left, nonmetals on the upper right, and metalloids in between.
Explanation:
Most of the groups in the Periodic Table of the Elements contain metals and metalloids. The Periodic Table arranges elements into metals, nonmetals, and semi/metals based on their properties. Metals are largely found on the left side of the table, nonmetals on the upper right, and a diagonal band of metalloids, or semi/metals, separates them. These metalloids exhibit properties that are intermediate between metals and nonmetals. Therefore, the correct option would be '1. metals and metalloids'.
Answer:
2. nonmetals and metals
Explanation:
Most of the groups in the periodic table of the elements are vertical columns, also known as groups. These groups are numbered 1 through 18 and are typically labeled on the left-hand side of the periodic table. Elements within a group have similar chemical properties and characteristics. For example, group 1 is known as the alkali metals and includes elements like lithium, sodium, and potassium. Group 17 is known as the halogens and includes elements like fluorine, chlorine, and bromine. There are a few exceptions to this general pattern, such as the lanthanides and actinides, which are not typically included in the main body of the periodic table.
