give three differences between elements and compounds
Answers
⊕Compounds contain different elements in a fixed ratio arranged in a defined manner through chemical bonds.
⊕compounds have ionic,van der Walls,or dispersion forces betwen them
elements have mettalic bonds between them
⊕example H20,NH3 is a compound
Cu,C,N,O are elements

ELEMENT
1) An element is usually defined as the simplest or the starting form of a Pure substance with a definite physical property and chemical property and which after all can neither get broken into nor built by them into or from simpler substances by any residing chemical and physical method.
This definition is usually regarded as incorrect since, many physicists and chemists have show that the elements can be broken down into and similarly get synthesized from simpler substances. With the much needed breakthrough and discovery as a fundamental unit of matter, the definition has been modified accordingly as follows;;
An Element is defined as a total pure substance that contains only one kind of particles and these particles may be shown as either atoms or molecules.
2) Carbon, Sulphur, iron, lead, gold, Mercury, hydrogen, oxygen and nitrogen are some of the examples which are known and familiar with elements. Thus, whereas iron, gold, copper, and so on, contain single atoms or constituent particles which are held together, in several cases, the constituent particles are molecular substances which are containing two or more atoms combined together in strong force.
For example, hydrogen, oxygen, nitrogen, so on, consists of molecules, comprising or containing two atoms combined in strong holdings together. The number of elements known to human kind and up to date are 118. Of these, only 94 occur naturally in the nature and in the earth's crust, some with extreme small quantities and the remaining of them are prepared artificially in laboratories through certain nuclear reactions for the benefit of science (approximately 24 synthetically created elements). Naturally occurring elements are distributed throughout the crust of the earth in many significantly varying proportions.
COMPOUND
1) Basically when speaking about a specific normal compound, it is nothing but,, Pure Substance, that have the containment of more than one kind of elements occurring in it or more than one kind of atoms present in the composition.
Furthermore it has been found out that the elements present in a compound are always in a specified fixed proportionate by mass. Hence, we can deduce that, and can be defined as the following;;
A compound is a pure substance containing two or more than two elements of combinational bonding or in togetherness in a fixed proportion by quantity of mass and which can also be or get further decomposed into constituent elements by suitable chemical methods. Further performs, the properties of compound are completely different by any means from those of its constituent elements.
2) For a specific example, Water, is a compound containing hydrogen and oxygen combined together in a total fixed proportion of 1:8 by the quantity or component by weight. It can be decomposed into its constituent elements,, that is,, hydrogen plus oxygen by passing some electricity as a mediator through the medium called water (Note: after acidifying or acidification this will make it a good conductor of electricity).
Now even going more Further,, the properties of water are completely different from its constituents, as,, hydrogen and oxygen. For another example,, hydrogen is a combustible gas or a gas able to perform the phenomenon of combustion, oxygen gas is a supporter of combustion whereas water on the other hand is neither combustible nor a supporter of combustion but it still extinguishes fire!
More or few more examples of compounds (all are points tho that's why) are carbon dioxide, Sulphur dioxide, sulphuric acid, nitric acid, hydrochloric acid, caustic soda, washing soda, baking soda, common salt, copper sulphate, sodium hypochlorite, dichlorodifluoromethane, dinitrogen oxide, calcium oxide, silicon dioxide, isopropyl alcohol, sodium tetraborate decahydrate, Alimunium phosphide, Ammonium cerium (IV) nitrate, etc. etc. etc.
