What does losing or gaining electrons make an atom?
4.7: Ions - Losing and Gaining Electrons
- Cations. A neutral sodium atom is likely to achieve an octet in its outermost shell by losing its one valence electron.
- Anions. Some atoms have nearly eight electrons in their valence shell and can gain additional valence electrons until they have an octet.

Why do atoms tend to gain or loose electrons?
Why do atoms want to gain or lose electrons? Explanation: Atoms and chemical species lose or gain electrons when they react in order to gain stability. Thus, typically, metals (with nearly empty outer shells) lose electrons to non-metals, thereby forming positive ions.
What are atoms that readily lose electrons?
What are 3 interesting facts about magnesium?

- Atomic weight (average mass of the atom): 24.3050.
- Density: 1.74 grams per cubic centimeter.
- Phase at room temperature: Solid.
- Melting point: 1,202 degrees Fahrenheit (650 degrees Celsius)
Do atoms become stable by gaining and losing electrons?
Some atoms become more stable by gaining or losing an entire electron (or several electrons). When they do so, atoms form ions, or charged particles. Electron gain or loss can give an atom a filled outermost electron shell and make it energetically more stable. What increases the stability of atoms?
What causes an atom to lose an electron?
Loss of an electron from an atom requires energy input. The energy needed to remove an electron from a neutral atom is the ionization energy of that atom. It is easier to remove electrons from atoms with a small ionization energy, so they will form cations more often in chemical reactions.
Why do elements tend to lose or gain electrons?
An element can give up electrons to achieve the electron configuration of the next lowest noble gas. An element can attract additional electrons to achieve the electron configuration of the next highest noble gas.
Why do atoms gain or lose electrons quizlet?
atoms share ,gain, or lose electrons when chemical bonds form. ionic bonds form when electrons are transferred from one atom to another atom. ions of different elements can combine by forming ionic bonds .
What atoms are most likely to lose electrons?
Encyclopædia Britannica, Inc. Metal atoms lose electrons to nonmetal atoms because metals typically have relatively low ionization energies. Metals at the bottom of a group lose electrons more easily than those at the top.
What happens when an atom loses an electron?
Follow Us: When an atom loses an electron, its overall charge becomes more positive by one. For example, a neutral atom would have a charge of positive one after losing an electron. All atoms tend to seek to be stable, which occurs when they have a neutral charge. When atoms don't have a complete outer orbital of electrons they will have ...
What happens when an atom doesn't have a complete outer orbital?
When atoms don't have a complete outer orbital of electrons they will have a negative or positive charge. In order to become neutral, they will seek to either gain new electrons or lose electrons through bonding. In general, metal atoms often have excess electrons and will try to donate them through ionic bonding.
