It becomes an ion.
This atom become an anion.
An atom that gains three electrons will become an ion with a 3- charge.
This atom gains electrons.
Ion
it becomes an ion
An atom that gains or loses valence (outermost shell) electrons is referred to as an ION.
Cations are positive ions, so an atom is supposed to lose electrons to become a cation. Anions are formed when an atom gains electrons.
It would have a negative charge. It would be a negative ion with a 2+ charge.Remember: when an atom gains electrons they become NEGATIVE.when an atom loses electrons they become POSITIVE.
Ions are formed when an atom gains or loses electrons and gets charged. If an atom gains electrons, number of electrons exceed from the number of proton and hence an atom gets negatively charged. Similarly if an atom looses electrons the total number of protons become more than the number of electrons.. and the atom becomes positively charged.
This neutral atom become a cation or an anion.
Gains two electrons. S 2-.
An atom gains a net charge by losing or gaining one or more electrons. If an atom loses one or more electrons, it will become a positively charged ion. If it gains one or more electrons, it will become a negatively charged ion.
