<span>A compound is a substance composed of two or more elements that are chemically combined in a fixed proportion. A molecule must be nonpolar if the molecule has a symmetrical charge distribution. A molecule must be nonpolar if the molecule has a symmetrical charge distribution. An electrolytic cell differs from a voltaic cell because an electrolytic cell requires an outside energy source for a nonspontaneous chemical reaction to occur. As electrons push each other around, the electron orbital clouds form different shapes. Scientists propose that atoms can have up to seven principle energy levels of electrons around the nucleus. This orbital diagram for nitrogen shows how electrons fill the sub-orbitals. Wave Mechanical .This is the electron configuration for the element sulfur, which has 16 electrons. We and everything around us are made of tiny groups of particles, called atoms. While atoms were once thought to be the smallest unit of matter, they are actually made up of much tinier, high-energy, negatively-charged particles circling at a crazy pace around a nucleus of positive and neutral particles. Since the outer-shell (valence) electrons control the chemical properties of a material, it would be useful to understand how they behave.</span>

A one or two letter symbol indicating a particular element two words no spaces
Andreyy89

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

A chemistry student needs 10.00 g of isopropenylbenzene for an experiment. He has available 120. g of a 42.7% w/w solution of is
babunello [35]

Answer:

The mass of solution the student should use is 23.4 g.

Explanation:

Hi there!

The concentration of the solution, 42.7% w/w, indicates that there is 42.7 g of isopropenylbenzene (IPB) per 100 g of solution. Then, if the student needs 10.00 g IPB, the mass of solution the student should take will be:

10.00 g IPB · (100 g solution/42.7 g IPB) = 23.4 g solution.

Then, the mass of solution the student should use is 23.4 g.
