SI stands for Système international, which is French for international system. This is due to its origin and the fact that the SI is controlled by a French organisation.
it cannot be mixed but it can be convert from SI--> CGS and CGS-->SI
The International System of Units, abbreviated "SI" from the French Le Système International d'Unités, is the modern form of the metric system.
Its SI unit is Ampere metre or Am.
The SI, or International System.
si units are based on the metric system system international (French) international system (English)
The letters cl stand for centilitre - there are 100 centilitres in one litre.
- Si is the chemical symbol for silicon- SI is an abbreviation for International System of Units

Ok Um, I do know the Answer, There are no Lone Pairs of Electrons in the Valence Shell of The Central Atom of SiCl4, because: Si has the Number Configuration of: 2,8,4 The '4' is the number of dots, it has surrounding Si, one above Si, one under Si, one on the right side of Si, one on the left side of Si. Cl has the Number Configuration of: 2,8,7 The '7' is the number of dots, it has surrounding Cl, you can have it in any order, i.e. one above Cl, two under Cl, two on the right side of Cl, two on the left side of Cl. But when you join SiCl4 together, and make it into a Lewis Structure, then the Central Atom is Si, Then Si will have one Cl bonding above Si, one Cl bonding under Si, one Cl bonding on the right side of Si, one Cl bonding on the left side of Si, and now all you can see, is that Si has Four Cl, attaching, bonding to Si, and now Si doesnt have any Lone Pairs
international system of units
Si is the symbol for silicon. Cl refers to chlorine. The compound formed by these elements is silicon chloride SiCl4.
ANSWER: It stands for Systeme Internationale
International System. (in French in the original.) a.k.a. the metric system.
The order is: Cl,S, Si, Al, Na.
Chemical symbols such as Cl for chlorine and Si for silicon have two letters because they are derived from the names of the elements in Latin or their English names. This system helps to uniquely identify each element without confusion.
SCl3. It is polar because it has a lone pair on the central atom.
