An ion is formed when an atom gains or loses an electron in bonding with another atom, causing the atom to become a positive or negative ion. Since electrons are negative, if an atom loses an electron, there are more protons (which are positive) than electrons, which causes the atom to become a positive ion (sometimes called a cation.) If an atom gains an electron it becomes a negative ion (or anion.) Ions are most commonly formed when two elements undergo ionic bonding, in which the elements 'give and take' electrons to gain full outer shells.
Ions are formed when an atom gains or loses electrons and gets charged. If an atom gains electrons, number of electrons exceed from the number of proton and hence an atom gets negatively charged.
Similarly if an atom looses electrons the total number of protons become more than the number of electrons.. and the atom becomes positively charged.
An ion forms when an atom acquire either extra or a deficiency of electrons. Positive ions form when an atom encounters another atom that has a higher affinity for its electrons. For example a sodium atom when it encounters a fluorine atom will give one of its electrons to the fluorine atom the sodium atom then becomes a +1 ion and the fluorine atom becomes a -1 ion.
There are two (not always opposing forces) that sometimes favour the formation of ions.
Sodium in its electro-static neutral state has one more electron than a noble gas configuration- so it has a desire to give up that electron, but also has a desire to keep it.
Fluorine in its electro-static neutral state has one electron short of a noble gas configuration - so it has a desire to get an electron, but also a desire not to.
When the two atom get together there is a balancing of desires and it is discovered that they would rather be noble gas configurations then electro-statically neutral - so atoms are formed.
NOTE: THIS DOESN"T REALLY ANSWER THAT QUESTION THAT WELL. IT DIDN'T FOR ME AT LEAST.When energy is imparted to an atom or molecule, this energy can cause an electron to be displaced from one of the electron shells in the atom or one of the atoms comprising the molecule. When this happens the atom or molecule is no longer electrically neutral and becomes an ion.
Ions are formed when certain elements fuse like salt dissolving into water.
By either adding or subtracting electrons from the atom.
By gaining or losing electrons the ions can return to their atomic state, like in electrolysis.
When an atom loss(positive) or gain(negative) of electrons they form its ion.
An ion is formed by loss (cation) or gain (anion) of electrons.
The ion formed by chlorine is the "chloride" ion
a bromide ion is formed, the ion formed has a -1 charge, and the ion formed is an anion
No, the atomic number does not change when an ion is formed. The number of protons does not change when an ion is formed, so the atomic mass would not change.
The hydronium ion which is written chemically as H3O+ will be formed when the water and the hydrogen ion combine. The ability of water to attract the hydrogen ion is what will lead to the formation of the hydronium ion.
Hydronium ion. [H3O]+
The ion formed by chlorine is the "chloride" ion
Hydroxonium H3O+ ion is formed.
a bromide ion is formed, the ion formed has a -1 charge, and the ion formed is an anion
+1 Na+ ion is formed
Fluoride Ion
No, the atomic number does not change when an ion is formed. The number of protons does not change when an ion is formed, so the atomic mass would not change.
The hydronium ion which is written chemically as H3O+ will be formed when the water and the hydrogen ion combine. The ability of water to attract the hydrogen ion is what will lead to the formation of the hydronium ion.
A hydrogen ion (H+)
The fluoride ion is the ion formed by the element fluorine
This ion is hydronium: (H3O)+.
A positive ion is formed when atoms lose electrons. When a cell gains an electron it becomes negative
It forms the Na+ ion.
