No, because compounds have completely different properties to the elements which combined to form them. For example Sodium is a highly reactive soft metal and Chlorine is a greenish yellow highly corrosive poisonous gas yet they react to form the compound Sodium chloride (common salt) which is a white, crystalline solid.
The chemical formula of the element Neodymium is Nd.
Hiya! humm...the question? "What sulfide compou nd will yield a black percipitate?" Don't get what that means? oh well.... No point in answering this question if I not gonna say much... okay.......... umm... err... well... Let me think...? I know what a compound is! It's two or more elements that are chemically joined together to make a compound. EASY! To find the difference between an element and a compound is, Element - Has only one Atom and Chemical - Has 2 or more Atoms. Hope this little piece of information can be useful for you? Sorry that I never gave you the answer to the question above. And... Bye :)
Nd is the chemical symbol for the element Neodymium.
The element with atomic number 60 is neodymium (Nd), which is a rare earth element commonly used in magnets and industrial applications.
Neodymium is an element on the periodic table of elements. It is abbreviated as Nd and has an atomic weight of 60. It is a silver metal that tarnishes in the air.
Nd (neodymium) is an element, so it is neither ionic nor covalent.
The symbol for neodymium is Nd. It is a rare-earth element with atomic number 60.
This chemical element is neodymium (Nd).
The chemical symbol of zinc is Zn; "macroscopic sample element" is a strange formulation in chemistry.
Identical molecules.
Because it is a element that is a liquid at a room tempeture
If your sample consists of four elements, each element represents 25% of the total sample. This is calculated by dividing 100% by the number of elements (100% ÷ 4 = 25%). Therefore, each element contributes equally to the overall composition of the sample.
