Radium Ra forms double positive ions (cations) symbol Ra++ or Ra +2
Fr+1 or Fr+, because Francium is an alkali metal (like Na or K) and forms 1+ charged ions by reduction of other substances (very reactive, explosive reaction, even with water!).
The chemical symbol of a chemical element is formed from one or two letters, extracted from the name of this element.
The chemical symbol of magnesium is Mg - the first and the third letter of magnesium. The chemical symbol of manganese is Mn - the first and the third letter of manganese.
No, only through chemical reactions. Physical changes never change the chemical makeup of something. For example, water tuning in to ice is a physical change. Ice and water both have the chemical symbol H20. On the other hand, a sodium - water reaction forms Sodium Hydroxide and Hydrogen. The compound, hydroxide, is formed.
The molybdenum chemical symbol is Mo.
Cl-1.
Symbol equations for reactions are written using chemical formulae.

The chemical symbol of a chemical element is formed from one or two letters, extracted from the name of this element.
The chemical symbol of hassium is formed from the first and the third letter of his name - Hs.
The chemical symbol of technetium - Tc- is formed by two letters from the name.
Plutonium chemical symbol is formed from the first and third letters of name - Pu.
The chemical symbol for lead (the element) is "Pb."
The chemical symbol of magnesium is Mg - the first and the third letter of magnesium. The chemical symbol of manganese is Mn - the first and the third letter of manganese.

Fe3O4 one of the iron oxides, commonly dark brown to black.
Not formula, but chemical symbol is Pu. No, he means formula (eg: Table Salt/ Halite - NaCl)
