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.
What else can I help you with?
What describes what happens when an atom becomes an ion with a two negative charge?
This atom gain two electrons and become an anion.
What happens when an atom loses one or more electrons and retains the same number of protons?
This atom become a positive ion (cation).
What happens when an atom loses an electron from its outer most shell?
well The electrons on that shell have nowhere to go so they jump off and become ionised
An atom can gaine or lose electronse to become an?
Ion.
When a lithium atom forms a Li plus ion the lithium atom does what?
THe lithoium atom has IONISED ( lost) an electron, to become the lithium ION.
What happens when an atom become an ion with a 2-change?
+2 or -2? Either way, nothing special happens.
What describes what happens when an atom becomes an ion with a two negative charge?
This atom gain two electrons and become an anion.
What happens when an atom loses one or more electrons and retains the same number of protons?
This atom become a positive ion (cation).
An atom can become an ion by losing?
An atom can become an ion by losing electrons. It can accomplish the same thing by gaining electrons.
Is helium an isotope atom or ion?
Helium is a neutral atom that has several isotopes and can become an ion.
What happens when atom looses electron?
If an atom loosed electrons then it becomes an ion. The electrical charge in the atom becomes a positive ion.
What does an atom become when it loses or gains electrons?
it becomes an ion
How does an atom becone an ion?
An atom looses or gains electron to become ion. Ions are +ve and -ve atoms.
What is an atom or group of atoms that become electrically charged?
IONS OS ION ^^A charged atom is called an ion
What happens to the radius when an atoms gains an electron to become a negative ion?
the radius increases when atom is converted to negatively charged anion.
When an atom loses a valence electron it becomes a what ion?
It will become a soft ion.
What happens when an atom loses an electron from its outer most shell?
well The electrons on that shell have nowhere to go so they jump off and become ionised
