Question

drag the tiles to the correct location on the table. not all tiles will be used.
match the properties to the family of elements they describe.
are placed in group 1 react vigorously with metals can be cut with a knife
are placed in group 17 are placed in group 12 dont react with any other
elements
alkali metals halogens

Explanation:

• Alkali Metals:
• They are located in group 1 of the periodic table.
• They are soft enough to be cut with a knife (due to weak metallic bonding).
• They react vigorously, but typically with non - metals (like halogens) to form ionic compounds. The statement "react vigorously with metals" is incorrect for them, and group 12 is for transition metals, not alkali metals, and they are reactive so "don't react with any other elements" is wrong. So the properties for alkali metals are "are placed in group 1" and "can be cut with a knife".
• Halogens:
• They are placed in group 17 of the periodic table.
• They are non - metals and are very reactive, and they react vigorously with metals (like alkali metals) to form ionic compounds (e.g., NaCl). Group 12 is not related to halogens, and halogens are reactive so "don't react with any other elements" is wrong. So the property for halogens is "are placed in group 17" and "react vigorously with metals".

Answer:

Alkali Metals	Halogens
