Question

A farmer has been using calcium for decades to help maintain chemical balance in the soil used to grow his crops. Unfortunately, the farmer's calcium supplier has been steadily increasing the price of their product to the point that the farmer no longer wants to buy calcium. Assuming they are offered at the same, cheaper price, should the farmer turn to magnesium (Mg) or potassium (K) as a new soil nutrient? E

Answer 1

I recorded a video answering your question. The answer would be Magnesium as that element has the same number of valence electrons as Calcium (They both have 2 valence electrons). This is because any element with the same valence electron configuration will react similarly during a chemical reaction and will have similar properties.
