Question

what are the group numbers of these metals?
drag the appropriate elements to their respective bins.

ba li al ca cs rb sr k na mg

group 1a group 2a group 3a group 4a

Explanation:

To determine the group of each metal, we use the periodic table groupings:

• Group 1A (Alkali Metals): Elements with 1 valence electron (Li, Na, K, Rb, Cs).
• Group 2A (Alkaline Earth Metals): Elements with 2 valence electrons (Ba, Ca, Sr, Mg).
• Group 3A: Elements with 3 valence electrons (Al).
• Group 4A: No metals from the given list (Ba, Li, Al, Ca, Cs, Rb, Sr, K, Na, Mg) belong here.

Answer:

• Group 1A: Li, Na, K, Rb, Cs
• Group 2A: Ba, Ca, Sr, Mg
• Group 3A: Al
• Group 4A: (No elements)
