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
If the humidity of the room is low, the water that contacts the air directly could evaporate and takes some energy from the bulk thus decreasing its temperature steadily. This allows the water to have a lower temperature.
It will either be B or D, but I don't know about burial.
So, to determine the number of neutrons in atom, we only have to subtract the number of protons from the mass number. Take note that the nucleus of an atom is composed of protons and neutrons. And the number of particles present in the nucleus is referred as mass number (Also, called as atomic mass).
