Answer:
The Symbols of elements is given by :
IUPAC : International Union Of Pure and Applied Chemistry .
Its is the Universally recognuised organisation which works on Chemical nomenclature and terminology.
Explanation:
According to IUPAC the elements are named according to mythological concept of country ,mineral , place , property and scientist.
Ex:Copper name comes from the old english word Cyprus.
Rules of Naming elements :
1. The first Alphabet of the element is always Capital.Example:-
Sodium : Na not ''na'
2. The second alphabet is always small .Example
Sodium : Na not ''nA' or NA
3.For most of the elements ,The symbol of the element comes from the <u>first two words.</u>
Example : Hydrogen : H
Helium : He
Copper : Cu
Rules for naming elements having mass> 100
1. The names are derived directly from the atomic number .
Ex : 0 = nil 1= un 2=bi 3=tri
2. The name always ends with ''ium''
For example :
102 = Unnilbium
The following will increase the strength of a copper electromagnet;
Adding more loops to the wire
Increasing the current
Explanation:
An electromagnet, a device that transforms electric energy into magnetic energy, has its magnetic field induced by an electric current. This current must be AC (alternating current) and not Direct Current (D.C) for it to work. Increasing the number of coils in the electromagnet increases the number of field lines of interaction between the current and the paramagnetic material. Increasing the current also makes the magnetic stronger.
