Answer:
Elements in the same group have similar properties because they have the same number of valence electrons.
Explanation:
What are valence electrons?
Valence electrons are the electrons on the outermost shell. For example take the element carbon or it’s symbol C. It’s has 4 valence electrons.

Answer:
Because they are the most destruction waves
Explanation:
Surface waves travel just below the earth’s surface. Examples of surface waves are Rayleighs and Long waves. Rayleighs cause ripples on the ground while long waves move the ground horizontally perpendicular to the direction of travel of the wave. Therefore, these waves are capable of destroying the foundations of structures and hence causing their collapse. Studying these waves allow these professionals to design foundations strong enough to withstand these waves.
I believe the answer is delta.
