Elements are represented by symbols which are based on their names, sometimes the symbols are based on old versons of their names... examples of element symbols are...
Oxygen = O
Helium = He
Nitrogen = N
Sodium = Na (its old name was Natrium)
Gold = Au (its old name was Aurum)
Compounds are represented by the sumbols and proportions of the elements they contain, examples are...
NaCl = Sodium Chloride (salt), one atom of Sodium plus one atom of Chlorine.
H2O = Water, two atoms of Hydrogen plus one atom of Oxygen.
HNO3 = Nitric Acid, one atom of Hydrogen plus one atom of Nitrogen plus three atoms of Oxygen.
What else can I help you with?
What do chemists use to represent elements and compounds?
Scientists use symbols to represent elements and compounds. The symbols of a chemical element are abbreviations that are used to denote a chemical element. Typically, they are one or two-letters long with the first letter (only) capitalised; temporary names are three-letters long. !
Can all elements form compounds?
Compounds are combinations of elements. They are different from molecules in the fact that Compounds cannot be a combination of the same element ( O2 ) instead compounds are combinations of different elements ( CO2 )
A chemical formula is an expression used to represent?
the type and number of atoms that make up a molecule. It provides information on the elements present in the compound and the ratio in which they are combined. Chemical formulas are a way to communicate the composition of substances in a standardized manner.
Are iron and silicon chemical compounds?
no both iron and silicon are elements. chemical compounds aretwo or more elements.
What elements do elements and compounds have in common?
Elements and compounds are both composed of atoms. Compounds are composed of two or more atoms of different elements.
Why do some elements have symbls that are different then the letters in there name?
It is greek name numbnuts!
What do chemicals symbols and formula represent respectively?
Respectively they represent elements and compounds.
What represent compound?
the combination of elements
Do oxygen and hydrogen represent the same compound?
No. Hydrogen and oxygen are elements, not compounds. They are not the same.
What are math symbls?
+ - * / () {} [] #(?) $ % = etc.
What are the differences between atoms and compounds?
both are pure substances, but atoms represent the smallest bits of elements. compounds are chemically combined atoms, molecules represent the smallest bits of compounds. atoms cannot be broken down into simpler substances, compounds can be broken down into atoms.
What does a formula tell you?
Chemical formulas are used to represent chemical compounds. It shows the component elements of the compound. Also it shows the ratios of the component elements.
How do elements relate to compounds?
Chemical compounds are formed from chemical elements.
What do chemists use to represent elements and compounds?
Scientists use symbols to represent elements and compounds. The symbols of a chemical element are abbreviations that are used to denote a chemical element. Typically, they are one or two-letters long with the first letter (only) capitalised; temporary names are three-letters long. !
What are the two type of substances?
Elements and compounds
What does it mean by represent elements compounds and mixtures in symbolic form?
Elements have symbols in thee periodic table For example: H is the symbol for the element Hydrogen H2O is the symbol for water
What do chemical equations show about compounds and elements?
Chemical equations represent chemical composition of reactants and products and also how does the reaction occur.
