Are sodium and francium elements or compounds?
Sodium and francium are elements. Elements are substances that cannot be broken down into simpler substances by chemical means, whereas compounds are substances composed of two or more elements chemically bonded together.
Is baking soda a pure subsances?
Baking soda is a compound made up of sodium, hydrogen, carbon, and oxygen atoms. It is considered a pure substance because it has a definite chemical composition and cannot be separated into simpler substances by physical means.
How is a substance different from an element?
An element is a pure substance made up of one type of atom, while a substance can be a pure element or a chemical compound made up of multiple elements chemically bonded together. In other words, all elements are substances, but not all substances are elements.
Why is adding water mixed to sodium a chemical?
When water is added to sodium, a chemical reaction takes place where sodium reacts with water to form sodium hydroxide and hydrogen gas. This is a chemical reaction because new substances are being formed with different properties than the original substances.
What substance can not be broken down by chemical means sodium water ethanol or sucrose?
Sodium is a pure element and cannot be broken down by chemical means into simpler substances like water, ethanol, or sucrose. It is a fundamental building block of matter with its own unique properties and cannot be further decomposed through chemical reactions.
Are sodium and francium elements or compounds?
Sodium and francium are elements. Elements are substances that cannot be broken down into simpler substances by chemical means, whereas compounds are substances composed of two or more elements chemically bonded together.

What would be regarded as compounds?
Compounds are substances formed by the chemical bonding of two or more elements. Examples include water (H2O) and sodium chloride (NaCl). Compounds have a fixed chemical composition and can be broken down into simpler substances through chemical reactions.
What is an element give 2 examples?
An element is a substance that cannot be broken down into simpler substances by chemical means. Two examples of elements are oxygen (O) and sodium (Na).
What substance can not be broken down by chemical means sodium water ethanol or sucrose?
Sodium is a pure element and cannot be broken down by chemical means into simpler substances like water, ethanol, or sucrose. It is a fundamental building block of matter with its own unique properties and cannot be further decomposed through chemical reactions.
What happens when sodium chloride is mixed with gold?
When sodium chloride is mixed with gold, there will be no chemical reaction as sodium chloride is a stable compound and gold is an inert metal. The two substances will simply mix together physically and can be separated again by physical means.
Elements and Compounds are called?
Elements and compounds are both types of substances. Elements are pure substances made of only one type of atom, while compounds are made of two or more different types of atoms bonded together. Elements cannot be broken down into simpler substances through chemical reactions, while compounds can.
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.
Why is sodium chloride a compound and not a mixture of sodium and chlorine?
Sodium chloride is a compound because it is formed by a chemical bond between sodium and chlorine atoms. In a compound, the elements are chemically bonded in fixed proportions, creating a new substance with different properties than its components. A mixture, on the other hand, is a physical combination of substances that can be separated by physical means. Sodium chloride cannot be separated back into its original elements by physical means.
Why are magnesium sodium and aluminium elements?
These elements are considered pure elemental substances because they cannot be broken down further into simpler substances by chemical reactions. They are made up of only one type of atom, each with its own unique chemical and physical properties.
