This is called a redox reaction. An atom that loses an electron is oxidized and an atom that gains an electron is reduced.
When an atom gains electrons, negatively charged anions are formed. When an atom loses electrons, positively charged cations are formed.
An atom becomes more positive when it loses an electron because electrons carry a negative charge. When an atom gains an electron, the atom becomes more negative.
It become an ion, positively charged when it loses an electron (called a cation, e.g. Na+) or negatively charged when it gains an electron (called a anion, e.g. Cl-).
Ions are made for clothes can not be wrinkly An ion is formed when an atom [or molecule] gains or loses one or more electrons. If an atom or molecule gains an electron it acquires negative charge. If the atom or molecule loses an electron it becomes positively charged.
when it gains or loses electron(s) (pretty much when it become charged, for short)
Ion. Any atom that loses or gains an electron becomes an ion.
An atom forms an ion when it gains or loses an electron. If an atom gains an electron, it becomes a negatively charged ion (anion). If an atom loses an electron, it becomes a positively charged ion (cation).
no
gains or loses an electron.
an atom that gains an electron becomes a negative ion, called an anion.
An ion is formed when an atom gains or loses an electrons or electrons. If it gains an electron, it becomes an anion, and if it loses an electron it becomes a cation.
Ion. Any atom that loses or gains an electron becomes an ion.
A neutral atom that subsequently gains or loses one [or more] electrons is called an ion. If it gains an electron [or electrons] it will have a negative charge. If it loses an electron [or electrons] it will have a positive charge.
An Ion. More specifically if it gains an electron it becomes an anion and it it loses an electron it becones an cation (pronounced Kat-ion)
When an atom gains electrons, negatively charged anions are formed. When an atom loses electrons, positively charged cations are formed.
