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.
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
The center of an atom is called the atom's nucleus. This structure is usually composed of protons and neutrons though some atoms of hydrogen have only protons.Full Answer >
A chlorite ion consists of one chlorine atom covalently bonded to two oxygen atoms. Chlorite ions are also known as chlorine dioxide ions or dioxidochlorate.Full Answer >
An enolate ion is a negative ion which is obtained by removing the hydrogen atom from ketone. Enolate ions can take two forms: one with a negative charge on the carbon atom and one having negative charge on the oxygen atom. Enolate ion consists of three atoms. The charge is distributed on the three atoms, which is how the enolate ion remains stable.Full Answer >
A phosphide ion is an negatively charged potassium atom that has three additional electrons in its outermost shell. Phosphide ions are nonmetallic and can chemically react with a variety of metallic elements to form ionic compounds.Full Answer >
