An atom becomes an ion when it loses or gains an electron. An atom is electrically neutral. The protons and electrons are equal and balance each other. An ion is either positive or negative, depending on whether it gains or loses an electron. Thus the number of electrons will be either greater or less than the number of positively charged protons.
An electron is removed or added to the atom. An ion is basically an atom with a charge. The charge is made positive by removing an electron and made negative by adding an electron. It does not change the element at all.
By losing or gaining one or more electrons.
It gains or loses an electron.
This atom gain two electrons and become an anion.
This atom become a positive ion (cation).
When an atom loses a negative charge, when it loses an electron, it becomes a positive ion.
well The electrons on that shell have nowhere to go so they jump off and become ionised
When an atom becomes an ion, it is because the atom now no longer has a neutral charge. Nothing really happens besides this, unless it reacts to a different element.
The neutral atom become an ion (cation) with the charge +1.
+2 or -2? Either way, nothing special happens.
This atom gain two electrons and become an anion.
This atom become a positive ion (cation).
The loss or gain of electrons transform an atom in an ion.
Oxide is the ion form of oxygen. It forms when an oxygen atom gains an extra two electrons. So an oxide ion would become an oxygen atom by losing two electrons.
An atom can become an ion by losing electrons. It can accomplish the same thing by gaining electrons.
Helium is a neutral atom that has several isotopes and can become an ion.
If an atom loosed electrons then it becomes an ion. The electrical charge in the atom becomes a positive ion.
When an atom loses a negative charge, when it loses an electron, it becomes a positive ion.
it becomes an ion
An atom of Calcium will lose an electron to become a posotive ion.
