Are noble gases metals or nonmetals? What is an inert gas on the periodic table? Why is calcium placed in 2 group although it has completely filled orbitals? Why is copper Cu on the periodic table? What are noble gases used for? Why is chlorine a nonmetal? What is the mass number of...
What is the evidence for electron waves? Give a practical application. Explain why calcium is generally more reactive than magnesium. Why do hydrogen atoms emit or absorb only discrete amounts of energy? Explain why even if a chemical reaction has a yield close to 100%, the atom economy may...
And Calcium so you’ll grow strong.Scandium,Titanium,Vanadium and Chromium and Manganese.This is the Periodic Table,Noble gas is stable.Halogens and Alkali react aggressively.Each period will see new outer shells.While electrons are added moving to the right.Iron is the 26th,Then Cobalt,Nickel...

They are composed of minerals uncommon on Earth, all rich in calcium, aluminum, and titanium, the most refractory (resistant to melting) of the major elements in the nebula. The same minerals that occur in refractory inclusions are believed to be the earliest-formed substances to have condensed...
