when it gains or loses electron(s) (pretty much when it become charged, for short)
An atom with a charge is called an ion. If the atom gains electrons, it becomes a negative ion (anion), while if it loses electrons, it becomes a positive ion (cation).
An atom that has gained an electron becomes a negatively charged ion.
If the atom loses electrons, the atom becomes positively charged because the number of positively charged protons.
When the number of electrons changes, the atom becomes an ion. An atom becomes a positively charged ion (cation) when it loses electrons and a negatively charged ion (anion) when it gains electrons.
an atom becomes positive when that atom gives their electron to other atom....when the atom reacts it is called ion not atom... so that means that ion has charge of ion+..... atom has to give or take( in this case give) electron to make their outer most shell full
If an atom loosed electrons then it becomes an ion. The electrical charge in the atom becomes a positive ion.
An atom with a charge is called an ion. If the atom gains electrons, it becomes a negative ion (anion), while if it loses electrons, it becomes a positive ion (cation).
an atom that gains an electron becomes a negative ion, called an anion.
yes...on gaining an electron, the atom becomes an anion i.e. negatively charged ion.
An atom that loses electrons becomes a positively charged ion called a cation. An atom that gains electrons becomes a negatively charged ion called an anion.
ION A positively (+) charged ion is named a CATION A negatively (-) charged ion is named an ANION NB When an atom becomes a charged species it is no longer an atom, but an ION . An atom has a neutral charge.
When an atom becomes ionized, it gains or loses electrons (usually one).
An atom can become an ion by either gaining or losing electrons. If it gains electrons, it becomes an anion. If it loses electrons, it becomes a cation. An ion is merely an atom with a charge, either positive or negative.
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.
Positive ion
When an electron is transferred from a sodium atom to a chlorine atom, the chlorine atom becomes a negatively charged ion because it gains one electron. This negatively charged ion is known as chloride ion.
An atom that has gained an electron becomes a negatively charged ion.
