What else can I help you with?
What was contained in the luminescent paint base that was used to inscribe numbers on watch dials in the 1920s?
A paint containing radium.
What does the compound formula ZnS stand for?
The compound formula ZnS stands for zinc sulfide. It is a binary compound made of zinc (Zn) and sulfur (S) atoms in a 1:1 ratio. Zinc sulfide is commonly used in the production of luminescent materials and as a pigment in paints.
What is the mass number of the radium isotope used in paint?
The atomic mass of the radium isotope 226Ra is 226,025 409 8(25).
What is selenium sulfide lotion for?
Can selenium sulfide be used in treatment for lice?
Why is hydrogen sulfide used to restore the color of old paintings?
Hydrogen sulphide is a toxic gas; also dangerous for paintings containing lead colours and for objects made from silver. You think probably to hydrogen peroxide (H2O2), used for restoring.. Lead (II) trioxocarbonate (IV) in white Lead (II) paint is converted to lead (II) Sulphide by atmospheric Hydrogen Sulphide. This reaction darkens the colour of the Paint. Hydrogen Peroxide is added to the Paint to restore the colour where it oxidizes the Lead (II) Sulphide to Lead (II) tetraoxosulphate (VI).

What is zinic used for?
Dietary supplements, deodorants, dandruff shampoo, luminescent paint, mix it with copper and make brass, it is used in batteries, etc.
Why was radium used in luminous paint?
Alpha particles emitted by radium produce radioluminescence is zinc sulfide.
What is the mass number of the radium isotope used in paint?
The atomic mass of the radium isotope 226Ra is 226,025 409 8(25).
What element is used in self luminous paint?
Radium self luminescent paint hasn't been used in decades since the hazards of it's ionising radiation became widely known. Modern technology of self luminescent paint seems to be based on tritium gas in a similar concept to tritium glow sticks but instead contained within micro particles. These micro particles can be painted on or made in to solid plastic. It is self luminous for 20+ years with a 12 year half-life. The company MPK who invented it calls the technology Litrospheres and also has plans for using it to self power solar panels as an energy source. At the present time this self luminescent paint, plastic or energy source technology has not been made available to the public.
Na2s explain what this formula means?
Na2S represents the compound sodium sulfide. It consists of two sodium (Na) atoms for every one sulfur (S) atom. Sodium sulfide is an inorganic compound commonly used in industrial settings, such as in the production of dyes and pharmaceuticals.
When was radium first used?
Probably after 1910, for luminescent dial paints.
What is selenium sulfide lotion for?
Can selenium sulfide be used in treatment for lice?
What is the name for compound H2S?
The most often used name is "hydrogen sulfide". It could also properly be called "dihydrogen sulfide."

Are there any novels about the radium dial painters?
Radium is not used as a component of luminescent paints from about 80 years !
