Concrete is a mixture.
Concrete is composed of cement and other cementitious materials such as fly ash and slag cement, aggregate (generally a coarse aggregate made of gravels or crushed rocks such as limestone, or granite, plus a fine aggregate such as sand), water, and chemical admixtures
Concrete is a heterogeneous mixture composed of cement, sand, gravel, and water. It is not an element or a compound.
Mixture
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.

Mixture.
Concrete is a mixture containing cement, sand, gravel and water.
Concrete is a mixture, not an element or a compound. It consists of various components, primarily cement, water, aggregates (such as sand and gravel), and sometimes additives. These materials combine to form a composite material that has specific properties suitable for construction.
Concrete is a mixture not a compound.

element. Sulfur dioxide (SO2) is a compound
KCl is a compound not an element.
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'.
Beryllium is an element. It is not a compound
cornstarch is a compound element.
