Hope this answer will help you.
Yes: with help from different machinery, the heavy metals can be discovered and can be used to build stronger products and create further positive solutions to life
No: Economically, the advances toward creating heavy metals are frowned upon. We could disrupt the physical features of the metals and cause a chemical reaction.
Answer:
Ca
Explanation:
Calcium atom has two electrons that are loosely attached to its outermost energy level. It easily looses these electrons during reactions than the other three elements ( aluminium,sodium and oxygen).
Ca₍aq₎⇒ Ca²⁺₍aq₎+2e⁻
Calcium ionizes by losing 2 electrons from its outer shell to form an ion with a charge of 2+
