Your brother recently joined the football team. He feels tired after each days practice and is unable to continue with his homework. Is there a connection between his tiredness and
nutrition he takes? If yes, give reason, also design a healthy diet plan for him.

i think the answer is composed of atoms

the alkaline earth metals (beryllium (be), magnesium (mg), calcium (ca), strontium (sr), barium (ba), and radium (ra)) are a group of chemical elements in the s-block of the periodic table with very similar properties: shiny. silvery-white. hopefully this ? i didn't fully understand the question
