What happens when radium reacts with?
Radium is a silvery-white metal. Radium’s chemistry is similar to that of the other alkali earth metals. It reacts very vigorously with water to form hydrogen gas and radium hydroxide. It reacts with even more vigorously with hydrochloric acid to form radium chloride.
What happens when a chemical reacts with oxygen?
The reaction between oxygen and another element generally results in the formation of a binary compound known as an oxide. The reaction itself is known as oxidation. For example, the oxidation reaction between oxygen and sodium produces sodium oxide. In many cases, an element may form more than one oxide.
What is the formula for radium oxide?

| Radium Oxide | RaO | 241.9994 |
What would you see when radium reacts with water?
Radium will react with water to make radium hydroxide and hydrogen – and you should be able to write an equation for this (because it will be just the same as the rest of the group).
What does oxygen bond with?
Oxygen has 6 valence electrons and prefers to either share two electrons in bonding with carbon, leaving the 4 nonbonding electrons in 2 lone pairs :O: or to share two pairs of electrons to form the carbonyl functional group.
Is radium oxide ionic or covalent?
Most radium compounds are therefore simple ionic compounds, though participation from the 6s and 6p electrons (in addition to the valence 7s electrons) is expected due to relativistic effects and would enhance the covalent character of radium compounds such as RaF2 and RaAt2.
What happens when barium reacts with oxygen?
Formation of Peroxides Strontium and barium will also react with oxygen to form strontium or barium peroxide. Strontium forms this if it is heated in oxygen under high pressures, but barium forms barium peroxide just on normal heating in oxygen.
What metal does not react with oxygen when heated?
The two metals which do not react with oxygen even at high temperatures are silver and gold.
What happens when radium is mixed with oxygen?
Radium react with oxygen 2Ra + O 2 2RaO [ Check the balance ] Radium react with oxygen to produce oxide radium.
What are the properties of the metal radium?
Available radium properties… Radium is a silvery white metal. The surface of radium metal is covered with a thin layer of oxide that helps protect the metal from attack by air, but to a lesser extent than the corresponding layer in magnesium.
What makes the surface of radium silvery white?
Radium is a silvery white metal. The surface of radium metal is covered with a thin layer of oxide that helps protect the metal from attack by air, but to a lesser extent than the corresponding layer in magnesium.
Which is more reactive with air magnesium or radium?
Radium, four places below magnesium in the periodic table is more reactive with air than magnesium. Reaction of radium with water. Radium probably reacts very readily with water to form radium hydroxide, Ba(OH)2 and hydrogen gas (H2).
