What is the Smallest unit of substance of two or more atoms?
The smallest unit of a pure substance that consists of two or more atoms held together by a chemical bond is a molecule.
What is the smallest unit of pure substance that can be broken down into individual atoms?
The smallest unit of a pure substance that still has the chemical properties of that substance is called an atom. Atoms can be further broken down into subatomic particles such as protons, neutrons, and electrons.
Which terms refer to the smallest pure substances elements and isotopes mixtures and alloys metals and nonmetals molecules and atoms?
An atom is the smallest particle possible of a pure substance. A molecule is the smallest possible particle of a compound.
A pure substance whose smallest unit is made up of atoms of more that one element?
compound
What pure substance whose smallest unit is made of atoms of more than one element?
This is called a compound.
What pure substance can be broken down chemically?
into smallest partical
What is the smallest part of a substance that has chemical properties of that substance?
Molecule, or atom in the case of a pure elemental substance.
What is the Smallest unit of substance of two or more atoms?
The smallest unit of a pure substance that consists of two or more atoms held together by a chemical bond is a molecule.
What is the smallest unit of pure substance that can be broken down into individual atoms?
The smallest unit of a pure substance that still has the chemical properties of that substance is called an atom. Atoms can be further broken down into subatomic particles such as protons, neutrons, and electrons.
What is the smallest and most simple type of pure substance?
A single hydrogen atom.
Which terms refer to the smallest pure substances elements and isotopes mixtures and alloys metals and nonmetals molecules and atoms?
An atom is the smallest particle possible of a pure substance. A molecule is the smallest possible particle of a compound.
Is a pure substance Whose smallest unit is made of more than one element?
two or more substances that are together that are together but do not combine to form a new, pure substance
What Difference between element and atom?

Smallest part of a pure substance?
If the pure substance is not an element, the smallest part is a molecule (which is made of atoms) for instance, pure water is made of water molecules, which are made of 2 hydrogen atoms and 1 oxygen atom If the pure substance is an element, the smallest part is an atom. (which is made of Protons, Neutrons, and Electrons) Pure hydrogen is made of atoms. A stable hydrogen atom has 1 proton, 1 neutron, and 1 electron. Protons and Neutrons can be broken down further into Quarks, Leptons, and Bosons. The Electron is a type of Lepton.
What are two reasons why density is a useful property for identifying substances?
Density is specific for each substance. Also the measurement is generally simple.
