Question

1. check if each statement describes an alkali metal, an alkaline earth metal, or a transition metal.

includes many metals like copper, silver, and gold
produces the most vibrant color when exposed to flame
has one valence electron
has two valence electrons
found in groups 3 - 12
found in group 1
found in group 2
found in the d block
most reactive, especially with water
high melting point

1. order the metals from most reactive to least reactive.

alkaline earth metal
alkali metal
transition metal

Explanation:

Each statement is matched to the correct metal type based on periodic table properties and reactivity trends:

1. Copper, silver, gold are classic transition metals.
2. Alkali metals produce vivid flame test colors.
3. Alkali metals have 1 valence electron.
4. Alkaline earth metals have 2 valence electrons.
5. Groups 3-12 are the d-block (transition metals).
6. Group 1 contains alkali metals.
7. Group 2 contains alkaline earth metals.
8. The d-block corresponds to transition metals.
9. Alkali metals are the most reactive with water.
10. Transition metals have high melting points due to strong metallic bonding.
11. Reactivity trend: Alkali metals (group 1) are most reactive, followed by alkaline earth metals (group 2), then transition metals (least reactive).
