Question

atomic number quick check
an element is highly conductive, highly reactive, soft, and lustrous. the element most likely belongs to which group? (1 point)
○ alkali metals
○ transition metals
○ noble gases
○ metalloids

Explanation:

1. Recall the properties of each group:

• Alkali metals (Group 1) are highly reactive, soft (can be cut with a knife), lustrous, and good conductors of heat and electricity.
• Transition metals are less reactive (compared to alkali metals), harder, and have variable oxidation states.
• Noble gases are inert (non - reactive), gaseous at room temperature, and poor conductors.
• Metalloids have properties intermediate between metals and non - metals, and are not typically highly reactive or soft like the described element.

1. Match the given properties (highly conductive, highly reactive, soft, lustrous) with the group properties. The properties match those of alkali metals.

Answer:

A. alkali metals
