Question

what characteristic is shared by elements in groups 3-12 (transition metals)? * 1 point they have 8 valence electrons they are all gases they are poor conductors of electricity they are less reactive than alkali metals

Explanation:

1. Analyze Option 1: Transition metals don't all have 8 valence electrons (their valence electron count varies and is not fixed at 8).
2. Analyze Option 2: Transition metals are not all gases (most are solids, e.g., iron, copper).
3. Analyze Option 3: Transition metals are good conductors of electricity (they have free electrons for conduction), so this is incorrect.
4. Analyze Option 4: Alkali metals (Group 1) are very reactive. Transition metals are generally less reactive than alkali metals, which matches their properties.

Answer:

They are less reactive than Alkali Metals
