Question

6 drag and drop the right answer in the answers below. group 1 elements have the lowest ionization energy (it is easy to steal an electron from them). they are known as the alkali metals. drag & drop the answer noble gases halogens alkaline earth metals transition metals 17 2 18 note: use ctrl+d to drag the option via keyboard

Explanation:

Group 1 elements in the periodic table are alkali metals and have the lowest ionization energy among main - group elements as they have one valence electron which is easily removed.

Answer:

Group 1 elements are alkali metals. The other options do not match the description. Noble gases have high ionization energies as they have a full outer - shell configuration. Halogens are in Group 17 and are non - metals with relatively high ionization energies compared to Group 1. Alkaline earth metals are in Group 2 and have higher ionization energies than Group 1 elements. Transition metals have more complex electron configurations and generally higher ionization energies than Group 1 elements. The numbers 17, 2, and 18 refer to other groups in the periodic table and do not match the description of elements with the lowest ionization energy. So the correct answer is that Group 1 elements are known as alkali metals.
