CHEMICAL ELEMENTS WORKSHEET FULL

Both elements and compounds have an even appearance and composition as long as they retain their particular atomic or molecular composition.Įlements and compounds are composed of atoms that stay together through bonds. Water will remain pure with its composition of oxygen and hydrogen but put a spoonful of sugar in it and it turns impure. Pure substances are homogenous because all the molecules or atoms that combine to form them have the same chemical and physical properties. This property of having properties indicates that the substance is pure.Įlements and compounds are pure substances, whereas mixtures are not. But breaking a compound would result in the loss of its specific chemical properties. In a way, they both are pure since breaking them down would only result in similar types of sub-particles. If an element comprises one atom, compounds are made up of only one kind of molecule. Whereas the compound, carbon dioxide, has two carbon atoms and one oxygen atom. An element has only one kind of atom, whereas compounds contain different atoms. Elements and compounds are both made up of atoms. Two or more atoms combine to form molecules. The basic building block of matter is an atom. In a periodic table, the columns represent elements of similar properties and groups. The periodic table lists elements according to their atomic numbers, from the lowest atomic number to the highest.

Their difference is that elements comprise one type of atom, whereas a compound comprises different elements. Pure substances may be elements (cannot be separated into simpler substances) and compounds (can be separated into simpler substances and elements).Įlements and compounds are two forms in which natural substances are found. The matter is classified into pure substances and mixtures. Matter is simply anything that occupies space and has mass.
