A
The elements in Group A1 on the periodic table are alkali metals, alkali earth metals, inner transition metals, and halogens.
To determine the elements in Group A1 on the periodic table, we need to know which version of the periodic table you are referring to. The traditional version divides the periodic table into Groups and Periods. However, the current standard version is the long form of the periodic table, also known as the extended periodic table.
In the traditional version, Group A1 typically refers to alkali metals. Alkali metals include elements such as Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Rb), Cesium (Cs), and Francium (Fr). These elements are known for their low electronegativity, high reactivity, and tendency to form positive ions with a +1 charge.
In the extended periodic table, the division into groups can vary depending on the specific version being used. However, the alkali metals are typically found in Group 1, which is located on the far left of the table.
It's important to note that the term "A1" is not commonly used to designate a specific group in the periodic table. Instead, elements are usually identified by their group number or name. If you are referring to a different periodic table or have more specific information, please provide additional details.
