Some atoms gain or lose electrons to form ions because they like to maintain
electro-stability .
For example, certain atoms such as oxygen will gain electrons to become more stable so they do not react as bad as when their electron shell is not full .
Let's take as an example common table salt (NaCl).
When it is in its' solid form it forms a stable compound that we sprinkle on our food (not too much I hope). But when we add it to water the water pulls the two atoms apart. The Na (sodium) loses on electron in its' outer valence shell (kinda like the orbit of the moon) and the Cl (clorine) atom gains this electron and puts it into its' outer shell. The reason they do this is because atoms like to maintain electro-stability.
An ion is a charged species but atoms are not, therefore they have to gain or lose electrons to become an ion. It has to be energetically favorable for them to do this. As an example, Fluorine would much rather be F- than F as F- is isoelectronic with Neon. In other words has a stable octet of electrons.
Some atoms gain or lose electrons to form ions because they need to become more stable. They sometimes give them to have an outershell or gain them to get a closer charge to eight.
to become more stable .
Negative ions form when atoms GAIN valence electrons.
Ions. Cations have lost electrons and have a positive charge. Anions have gained electrons and have a negative charge.
Nitrogen atoms gain 3 electrons and form the nitride ion, N3-. Nitrogen atoms also form covalent bonds where they share 3 electrons and do not become ions. Bromine atoms gain 1 electron and form the bromide ion, Br-. Bromine atoms also form covalent bonds when they share 1 electron and do not become ions.
Ions
Ions are formed when atoms gain or lose electrons. Positively charged cations are formed when atoms lose electrons. Negatively charged anions are formed when atoms gain electrons. Ionic bond is the force of attraction between cations and anions.
Electrons always have their charge, when atoms gain electrons, they become ions.
All atoms become positive ions when they lose electrons, and negative when they gain electrons.
they are ions
ions
When atoms lose or gain electrons, they form ions. These are charged particles.
The non-metallic atoms will gain electrons, while the metallic atoms will lose electrons to become ions. An ionic compound is thus formed and all ions will have the noble gas configuration/structure.
Negative ions form when atoms GAIN valence electrons.
No. Atoms of an element lose or gain electrons to form ions.
It is called an Ion either a cation where electrons are lost or anion where electrons are gained
The number if electrons it has. Neutral atoms have the same number of protons (pos charge) as electrons (neg charge). When atoms gain or lose electrons (to become more stable), they become ions.
