What is a charged ion?

Answer 1

when a molecule is attacked by electrons in general either they accept the electrons (m + e- =

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-)

Answer 2

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.

Answer 3

A charged ion is an atom or molecule that has gained or lost one or more electrons, resulting in a positive or negative charge. Positively charged ions are called cations, and negatively charged ions are called anions. Charged ions are important in many chemical reactions and biological processes.

Answer 4

An atom that has an unusual number of electrons. A 3+ ion has 3 more protons than electrons.

Answer 5

A metal atom which is missing 2 electrons, like Mercury(II)

Answer 6

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).
