I would imagine you mean water, air earth and fire....that was just what the Greek philosopher Plato thought. The only elements are on the Periodic Table for example, helium, gold, Mercury and over 100 others. The definition of an element is having one type of atom. earth, water, fire, and air all have multiple kinds of atoms. Common mistake, the real major groups are metals, semimetals, nonmetals, and noble gases.
Seven of the most common functional groups are:
1) Hydroxyl group (-OH)
2) Carbonyl group (>CO)
3) Carboxyl group (-COOH)
4) Amino group (-NH2)
5) Sulfhydryl group (-SH)
6) Phosphate group (-OPO32-)
7) Methyl group (-CH3)
The dash (-) at the beginning of each group means that the first atom listed bonds with other atoms or functional groups to form molecules. In the case of the carbonyl group, the ">" symbol means that the carbon atom bonds to two other atoms or functional groups.
Example 1: sodium chloride (table salt)
Chemical formula: NaCl
Composition: sodium (39,34 %), chlorine (60,66%)
Example 2: iron(III) oxide
Chemical formula: Fe2O3
Composition: iron (69,94 %), oxygen (30,06 %)
The seven groups of classification are : Kingdom, Phylum, Class, Order, Family, Genus, Species
You can remember them with riddles like

The seven major chemical groups of minerals are sulfides, native elements, silicates, sulfates, carbonates, oxides and halides.
Following are the 7 food chemical groups such as :
1. carbohydrates
2. fibre
3. fats
4. proteins
5. minerals
6. vitamins
7. water
Some great examples could be : alkali metals, alkaline earth metals, halogens, or noble/inert gases.
Alkali, Alkaline earth, Halogen, oxygen, Nitrogen, carbon are the main families in the periodic table.
No. In a physical change, the substance maintains its chemical composition.
What is the chemical composition of kf reagent
Chemical properties of paper can include flammability/nonflammability or decompostition/lack of decompostition at high temperature.
Phosphorus is one of the chemical elements and therefore has no "chemical composition" in the usual sense.
Assuming your gold is pure : Chemical composition = Au Chemical formula = Au
Examples: iron sulfide and some copper alloys.
Chemical Composition
Examples: chemical reactivity, flammability, solubility, chemical composition, homogeneity or heterogeneity, toxicity.
No. In a physical change, the substance maintains its chemical composition.
No, a chemical composition refers to the types and ratios of elements present in a substance, whereas chemical properties describe how a substance behaves or reacts with other substances. Chemical properties include characteristics such as reactivity, stability, flammability, and toxicity.
Water and Ice.
Examples:- the state of matter- the chemical composition- the chemical properties- the physical properties
Examples of the characteristics of matter: state of matter, density, radioactivity, thermal properties, electrical properties, optical properties, chemical composition, etc.
soem examples of chemical sedimantery rock are limestone, and gypsum.
What is the chemical composition of kf reagent
The chemical composition remain unchanged.
the chemical composition does not change.
