An element consists of only one type of atom e.g. gold contains only gold atoms.
A compound is two or more elements chemically combined eg. Carbon Dioxide, CO2, which contains one Carbon atom and two Oxygen atoms.
To calculate the grams of an element in a compound, you need to find the molar mass of the element and the compound. Then, use the formula: (mass of element/molar mass of compound) x molar mass of element. This will give you the grams of the element in the compound.
No such thing as a 'Compound element'. It is either a 'Compound' or an 'Element. Germanium is an element that appears in the Periodic Table as 'Ge'. NB A compound is a COMBINATION of two or more different elements.
To find the mass of an element in a compound, you can use the formula: mass of element (mass of compound) x (percent composition of element in compound). This formula helps you calculate the mass of a specific element within a compound based on its percentage composition.
Gravel is a mixture of different compounds and elements, such as rocks, minerals, and organic materials. It is not a single compound or element itself.
Ammonia is a compound composed of nitrogen and hydrogen atoms.
INTENT
the number of protons
An element's atomic number, or number of protons, differentiates one element from another.
pitch
element. Sulfur dioxide (SO2) is a compound
KCl is a compound not an element.
cornstarch is a compound element.
Beryllium is an element. It is not a compound
First of all you have mispelled it as 'hellium' . It is 'HELIUM'. It is an element. It atomic No. is '2' , so therefore it is found in position number '2' in the Periodic Table, as 'He'. It is neither a compound nor a mixture. The chemical symbol for helium is 'He '. It's Atomic Mass is '4' It is compsed of 2 protons, 2 neutrons and two electrons. It is the MOST Noble(Inert) of all the elements. It does NOT react with anything. Therefore it exists 'monatomically' (single atoms). Its condensing point is 7 K ( - 266 oC) (Becomes a liquid) Its freezing point is 4 K . ( - 269 oC) (becomes a solid). The name 'helium' is from Classical Greece, and means 'from the Sun'(Helios), because two hydrogen atoms fuse together in the Sun , they form 'Helium'.
Mixture
if it dissolves its a compound if not its an element.
NO = Nitrous Oxide - compound No = Nobelium - element
