When an atom has gained or lost electrons.
We have the Hydrogen atom ; 1 proton and 1 electron .
Then we have the hydrogen ion ; 1 proton and no eletrons (Denoted as H^+)
Conversely we have the chlorine atom ; 17 protons, 18 neutrons and 17 electrons
The we have the chloride ion ; 17 protons, 18 neutrons and 18 electrons ( denoted as Cl^-).
NB An atom that has becomes charged is known as an ION. It is no longer an atom.
Positively charged ions are known as CATIONS and negatively charged ions are known as ANIONS.
Group of atoms can form ions too . Notably the sulphate ion (SO4^2-) of the Nitrate ion ( NO3^-)
There are many different cations and anions.
m-) or they release one electron (m + e-=
m++ 2e- ) but rarely if they release two electrons then they are called doubly charged ions(m
+ e-=
m2+ + 3e-)
An atom that has an unusual number of electrons. A 3+ ion has 3 more protons than electrons.
It has two less electrons than protons (assuming it is not in a solution) giving it a 2+ charge on a relative scale or a charge of approx. 3.205468x10^-19C (in Coulombs).
It depends, a proton if is is positively charged ( +) electron if it is negatively charged ( - )
an ionAn atom is electrically neutral as they have the same number of positively charged protons and negatively charged electrons.
Electrons are negatively charged (around the nucleus) and protons are positively charged (inside the nucleus)
A positively charged ion (cation) is attracted to a negatively charged ion (anion). Cations have more protons than electrons, whereas anions have more electrons than protons. Electrons are negatively charged, and protons are positively charged.
A positively charged ion is called a cation while a negatively charged ion is called a anion. It obtains a positive charge when it gives out electrons to another atom to gain stability. A positively charged ion is called a cation while a negatively charged ion is called a anion. It obtains a positive charge when it gives out electrons to another atom to gain stability.
A negatively charged ion is an anion.
An ion is a positively or negatively charged atom or molecule.
A charged atom is an ion. A positively charged version is a cation and a negatively charged one, an anion.
yes. negatively charged ion is called cation and where as a positively charged ion is anion.
it's a simultanious attraction between a positively charged ion and a negatively charged ion it's a simultanious attraction between a positively charged ion and a negatively charged ion
It depends, a proton if is is positively charged ( +) electron if it is negatively charged ( - )
A charged atom is an ion. An atom that has lost one or more electrons becomes a positively charged ion called a cation. An atom that has gained one or more electrons becomes a negatively charged ion called an anion.
IONS OS ION ^^A charged atom is called an ion
an ionAn atom is electrically neutral as they have the same number of positively charged protons and negatively charged electrons.
a positively charged sodium ion and a negatively charged chlorine ion.
Chloride ion has a valence of negative 1.
