Here are several, in no particular order:
There are many more that I haven't listed (90 naturally occurring on earth, 2 synthetic radioactive below uranium, several known transuranic, unknown number possible transuranic).
The Periodic Table is full of them. When we compare an element to a compound, the Element is the [spacial] assemblage of pure Atoms that exist alone, while the Compound is any number of many various combinations of any of the Atoms conjoined - or bonded together - in a vast number of different ways.
Yes, of course. Examples of elements are :-
Hydrogen (H)
Iron (Fe)
Sodium (Na)
Argon (Ar)
Gold (Au)
Silver (Ag)
Nitrogen (N)
Sulphur (S)
Carbon (C)
Oxygen (O)
Boron is a chemical element.
a chemical property.
Take the element "Iron" then the symbol for the element is "Fe" and "Fe" is also the symbol for a single atom of the element in a chemical equation.
This is the percent chemical composition.
The chemists' shorthand for elements is called chemical symbols. For example, instead of writing out 'selenium,' it can be quickly written as 'Se.'
A chemical symbol represents an element. For example, the chemical symbol H represents the element hydrogen.
It is an example of natural chemical element, a metalloid.
It is an example of natural chemical element, a metalloid.
Yes, copper is a chemical element.
Boron is a chemical element.
Iron (Fe) is a chemical element.
gold is an element
For example Kr for krypton.
a chemical property.
Curium, the chemical element is only curium !
An important example is platinum.
For example, water reacts with zinc, releasing hydrogen, an element.
