SO is not an element. It is simply a compound.
Each element is different so for a certain element to be define/determined it has different atoms to make it up so no other element has the same atoms
Beryllium has atomic no. 4.So it is the fourth element.
Pure Iron is an element with the symbol Fe.Pure iron is an element, but what is called "iron" in ordinary speech often contains some impurities and if so is a mixture.Iron is an element
The name of the element symbolized by the letter A on the periodic table will depend on the specific element being referred to. There is no specific element that is universally represented by the letter A.
Graphite is an element. It is composed entirely of carbon atoms arranged in a specific crystalline structure.
Nitrogen is an element, so no other element contains nitrogen.
Co is, itself, an element so there are no elements in it.
No. It made of silicon and oxygen, so its a compound. Silicon is an element and oxygen is an element
Gold is a pure element, not a compound, so it is homoatomic.
Copper is on the Periodic Table, anything on the periodic table is an element so copper wire is made from an element.
Gold is an element so it only contains the element, gold.
Hydrogen is an element. So the only element in hydrogen is hydrogen.
Each element is different so for a certain element to be define/determined it has different atoms to make it up so no other element has the same atoms
No. Melting does not change one element into another.
it is a chemical change so that is why it becomes a compound from a element
Beryllium has atomic no. 4.So it is the fourth element.
Aluminium is actually an element, so the only element in aluminium is aluminium.
