These atoms becomes ions.
When an atom looses an electron is called "a cation, when gains is called an "anion".
When an atom gains or looses a valence electron it becomes a charged particle called an ion
An atom looses or gains electron to become ion. Ions are +ve and -ve atoms.
If you are asking what it is called, when an atom looses or gains electrons it is called an ion. Electrons are negative, so when an atom looses electrons it becomes more positive and is called an cation. So, when an atom gains electrons it becomes more negative and is called an anion.
If it looses an electron, it becomes positively charged. If it gains one, it becomes negatively charged. These charged species are collectively called ions.
electrons. the atom either gains or looses electrons to become negatively or positively charged. An ion can also be formed by the addition or subtraction of a neutron.
When an atom gains electrons, it becomes negatively charged because it now has more electrons than protons. When an atom loses electrons, it becomes positively charged because it now has more protons than electrons.
an atom that gains an electron becomes a negative ion, called an anion.
Electrons.
An atom that gains or loses electrons is called an ion. When an atom loses electrons, it becomes positively charged and is called a cation. When an atom gains electrons, it becomes negatively charged and is called an anion.
An atom is electrically neutral; it has the same number of positively charged protons as it has negatively charged electrons. If an atom either gains or loses one or more electrons, then it will have an electric charge, and will be an ion.
An atom that gains or loses electrons is called an ion. If it gains electrons, it results in a negative ion called an anion. If it loses electrons, it results in a positive ion called a cation.
