A charged atom is called an ion. Atoms are neutral because they have the same numbers of positive and negative charges. By adding or taking away negative charges, atoms can become positive or negative.Know More
Protons and neutrons exist in the nucleus of an atom. Protons have a positive charge, whereas a neutron has no charge. Electrons are negatively charged particles that zoom around the nucleus.
Some elements are electropositive, while others are more electronegative. Atoms like to have a full outer electron shell, so they either try to gain or lose electrons to fill their outer shells. Electropositive elements such as lithium, whose atoms have few electrons in their outer level, will donate them to other atoms. They then become positively charged because they have more protons than electrons. Elements such as oxygen are electronegative and want to take electrons from other atoms, thus gaining a negative charge.Learn more about Atoms & Molecules
A negatively charged particle within an atom is called an electron. Electrons were discovered in 1897 by a British scientist named J.J. Thomson.Full Answer >
A negatively charged atom is called an anion. An anion forms when an atom gains electrons from another atom. Atoms are generally neutral, but they take on a charge when they gain or lose electrons.Full Answer >
An electrically charged atom is called an ion. Ions are formed when an atom either loses or gains an electron. Atoms tend to move toward a more stable electron configuration, which happens when an atom possesses an outer energy level filled with electrons.Full Answer >
An atom that has gained one or more electrons is called an anion. It is also known as a negative ion. A positive ion, or a cation is one that has lost one or more electrons.Full Answer >
