Substances are made of atoms, which are the basic building blocks of matter. Atoms are composed of a nucleus containing protons and neutrons, surrounded by electrons that orbit the nucleus. Each element is made up of a specific type of atom, determined by the number of protons in its nucleus.

What pure substances are made of only one type of atom?
Elements are pure substances made of only one type of atom. Examples include hydrogen, oxygen, gold, and carbon.
What are the two major subdivision of matter?
The two major subdivisions of matter are pure substances and mixtures. Pure substances are made of only one type of atom or molecule, while mixtures are made of two or more different substances physically combined.
What is a pure substance made of one atom and cannot be separated into simpler substances?
An element is a pure substance made of one type of atom that cannot be broken down into simpler substances by chemical means. Each element is defined by the number of protons in its nucleus, which determines its unique chemical properties.
What are Elements and counpounds?
Elements are pure substances that cannot be broken down into simpler substances by chemical means. They are made up of only one type of atom. Compounds, on the other hand, are substances composed of two or more elements chemically combined in a fixed ratio.
Are elements considered to be a substance?
Yes, elements are considered to be a type of substance. They are pure substances made up of only one type of atom.
Substances made of one kind of atom?
Elements
What is true about atom?
They are made up of a lot of different substances.
What pure substances are made of only one type of atom?
Elements are pure substances made of only one type of atom. Examples include hydrogen, oxygen, gold, and carbon.
What substances are made up of just one kind of atom?
Elements
What is made up of only one atom and has a chemical symbol and cant be divided into simpler substances?
An element is made up of only one type of atom and has a unique chemical symbol. Elements cannot be broken down into simpler substances by normal chemical means.
What can be a element?
A substance that is made of only one atom and cannot be broken down into simpler substances
What Cannot be Split into any simpler substances?
Elements are substances that cannot be split into simpler substances by chemical means. They are made up of only one type of atom.
What are the substances that are made up of a single type of atom called?
Substances made up of a single type of atom are called elements. Examples of elements include oxygen, gold, and carbon. Each element is unique based on the number of protons in its atomic nucleus.
What are the two major subdivision of matter?
The two major subdivisions of matter are pure substances and mixtures. Pure substances are made of only one type of atom or molecule, while mixtures are made of two or more different substances physically combined.
Are most substances elements?
All substances are MADE FROM elements but they are not elements. For example CH4 is made of one carbon atom and four Hydrogen atoms. Carbon and Hydrogen are pure elements but CH4 is not an element.
How do metallic substances facilitate current flow?
Metallic substances have free electrons, which can move from atom to atom, transferring a charge.
What is a pure substance made of one atom and cannot be separated into simpler substances?
An element is a pure substance made of one type of atom that cannot be broken down into simpler substances by chemical means. Each element is defined by the number of protons in its nucleus, which determines its unique chemical properties.
