Not according to the strict chemistry definition. You can, however, fission an element into smaller pieces.

A synthesis reaction is a reaction between two compounds in which?
A synthesis reaction forms a new compound from two other separate substances. The new compound is chemically distinct from the substances it was formed from.
When is an element said to be chemically reactive?
An element is said to be chemically reactive when it combines with another element. These two elements will create a new compound.
What do two or more elments combined chemically they form what?
a new element
The new substance formed when elements combine chemically n?
When elements combine chemically compounds are formed. For instance, when hydrogen and oxygen gases chemically combine, water is formed. Note that if a molecule is made up of only one element, it is referred to as an element, not a compound.
Helium can combine with what to form new substances?
helium does not combine with any element
A synthesis reaction is a reaction between two compounds in which?
A synthesis reaction forms a new compound from two other separate substances. The new compound is chemically distinct from the substances it was formed from.
What is the difference between physically blending and chemically combining substances?
Physically blending substances forms a mixture. Chemically combining substances forms a new substance, such as a compound.
When is an element said to be chemically reactive?
An element is said to be chemically reactive when it combines with another element. These two elements will create a new compound.
Does helium form any new substances?
No. helium is chemically inert.
What is a pure substance as an element?
it has to be chemically combined into a new substance
Is potassium can not be a substance to decomposed by chemical means?
Potassium is an element. Reacting it chemically will produce new chemical compounds but the the nucleus of the potassium ion is not affected, only the outermost electron shell which normally loses an electron forming the K+ cation
What two or more elements combined chemically form?
a new element
When two substances react chemically to produce a new substance what is TRUE of the mass of the two substances compared to the mass of the new substance?
Same. Mass is not changed.
What a two or more substances that are combined chemically?
Two or more substances which can chemically react form new chemicals after the reaction.1. If these chemicals react they form new compounds.2. Without a chemical reaction they form a mixture.Read more: What_is_two_or_more_substance_are_combined
What are two or more substances that are together but do not combine to form a new pure substance?
A mixture forms when two or more substances combine physically but not chemically.
What do two or more substances form when they are brought together without forming a new substance?
Two substances that are brought together, but not chemically combined to create a new substance, form a mixture.
Is sodium an element a compound or a mixture?
Sodium is an element, as it consists of just one type of atom. Its symbol is Na, atomic number 11. A compound on the other hand is two or more elements that have chemically bonded together, while a mixture can be defined as two or more substances that have been brought together, but have not reacted chemically to form a new substance.
