electrons
Electrons are the negatively charged sub atomic particles.
Elements that have gained or lost an electrons are called IONS. Ones that gained electrons (non-metals) and are therefore negatively charged, and known as ANIONS, and those that lost electrons (metals), are positively charged and known as CATIONS
an ionAn atom is electrically neutral as they have the same number of positively charged protons and negatively charged electrons.
We call this Conventional Current Flow, where imaginary positively charged particles are repelled away from a positive charge and attracted towards a negative charge.The reality is that electrons are actually flowing through the conductor. Electrons are negatively charged particles and flow from negative to positive. It's just easier to think of a positive current flowing than a negative current.
negatively charged ion.
When we bring a positively charged body towards a negatively charged body the negatively charged particles in the negatively charged body move towards the positively charged particles in the other body i.e an electric charge moves when we bring two bodies of differently charged bodies or the same charges(they repel each other in this case)
Thomson believed about atoms, that : An atom consists of a sphere of positive charge with negatively charged electrons embedded in it. Positive and negative charges in an atom are equal in magnitude, thus an atom is electrically neutral and it has no overall + or - charge.
Electricity can be conducted by several kinds of charged particles; the most common case is that it is conducted in a metal conductor, by particles called electrons.
conductor
Electrons. The areas in which we are likely to find electrons around the atom we call electron density. This is valuable in determining stuff like molecular geometries and how atoms chemically interact with eachother.
These elements are called ions. Elements choose to lose or gain electrons because they want to achieve electronic stability. All metals lose electrons and all non-metals gain electrons to get the respective stable electronic structure they want. As for metalloids, some elements in there gain while some lose electrons. When elements lose or gain electrons, they will form a charge, since the number of protons and neutrons are not balanced now. All non-metals form negative charged ions while all metals form positive charged ions. Compounds are formed when a positively charged ion is attracted to an negatively charged ion by the electrostatic force of attraction. For example, sodium chloride is a compound of sodium ion and chlorine ion. The positively charged sodium ion is attracted to the negatively charged chloride ion to form the compount.
