noble gases

Answer 1

In the context of the periodic table, groups 1, 2, and 3 refer to specific categories of elements. Here are examples for each:

• Group 1: This group contains alkali metals. Examples include lithium (Li), sodium (Na), and potassium (K). These are metals.

• Group 2: This group contains alkaline earth metals. Examples include magnesium (Mg), calcium (Ca), and barium (Ba). These are also metals.

• Group 3: This group contains elements that include metalloids and transition metals. An example from this group is aluminum (Al), which is a metal, or gallium (Ga), which is also a metal.

In summary:

• Group 1: Metals (e.g., Lithium, Sodium)
• Group 2: Metals (e.g., Magnesium, Calcium)
• Group 3: Metals/Metalloids (e.g., Aluminum)

Thus, the responses can be summarized with metals or metalloids depending on group interpretation, but groups 1 and 2 are definitely metals. Group 3 is predominantly metals, but also includes metalloids in extended classifications.
