- A molecule may contain different types of atoms.
- An element can be composed from different isotopes.
Pure substances have identical particles. This means that all samples of a pure substance will have the same type and arrangement of particles, whether they are atoms, molecules, or ions. Examples of pure substances include elements and compounds.
A pure substance is one in which 100% of the particles are the same. This is also a homogeneous substance.
False. The rate of a chemical reaction can be influenced by the size of the reactant particles. Smaller particles have a larger surface area, allowing for more frequent collisions between particles and therefore potentially increasing the rate of reaction.
A pure substance consists of only one type of element or compound. The composition of a pure substance always stays the same, with a fixed ratio of its constituent particles.
Particle theory explains that all matter is made up of tiny particles. In the case of pure substances, these particles are the same throughout the substance, giving it a uniform composition. This understanding helps in identifying and describing the properties of pure substances based on the behavior of their particles.

True, a pure iron frying pan and a pure iron nail have the same density, as density is a property intrinsic to the material itself and is independent of the shape or size of the object. However, the manufacturing processes and any potential impurities in each item could affect their practical density in specific instances. But in a theoretical sense, pure iron's density remains constant regardless of the form it takes.
No, the particles of a pure substance are all the same kind. In a pure substance, such as an element or a compound, the particles are identical in their chemical makeup. This is what distinguishes a pure substance from a mixture, where different substances can be present in varying proportions.
Element are the pure substances that contain atom of same kind. Atoms are fundamental particles of matter.
True. In a magnetized material, most of the domains are indeed aligned in the same direction, creating a magnetic field.
A pure substance in which all the atoms have the same atomic number or number of protons is an element.
