Dalton's atomic theory states that elements consist of indivisible particles called atoms and that atoms of the same element are identical in size, mass, and properties. Therefore, every sample of a pure substance will have the same properties because each sample is made up of the same type of atoms arranged in the same way.
a molecule
Copper is considered a pure substance because it is made up of only one type of atom, specifically copper atoms. There are no other elements or compounds mixed with it. This makes copper chemically uniform and homogeneous throughout.
If matter is made up of two or more elements and has the same ratio of atoms no matter the amount of the substance, it is a compound. A compound is a substance composed of two or more elements chemically bonded together in a fixed ratio.
ionic compund
All substances are made up of atoms. Atoms are the basic building blocks of matter and are composed of protons, neutrons, and electrons. These atoms combine to form molecules, which make up different substances.
A substance in which all atoms are identical is called an element.

An element is made by atoms. smallest part of element is atom.
None.An element is a pure substance, composed throughout by identical atoms, that cannot be broken down into simpler components by chemical means. Water is a compound, a substance composed of the combination of atoms of two or more elements into molecules; in this case, a molecule of water is made up of two atoms of hydrogen, and one atom of oxygen.
NO.Never. Element is a substance made up of a single type of atom.It is the compound made up of different atoms shantanu satpute class 9
Copper is considered a pure substance because it is made up of only one type of atom, specifically copper atoms. There are no other elements or compounds mixed with it. This makes copper chemically uniform and homogeneous throughout.
Matter is composed of identical atoms that make up elements. These atoms can combine to form molecules through chemical bonds, which in turn create the different substances we observe in the universe. The properties of matter are determined by the type of atoms present and how they are arranged.
compound
No. Elements are made up of smaller elements called atoms.
