If 2 are attracted to each other then they exchange (lose or gain) electrons so that their outer shell can be full. You should Google bohrs theory and diagrams.

Can atoms lose or gain atoms to form elements?

No. Atoms of an element lose or gain electrons to form ions.


How element form ions that have a stable atomic structure like that found in a noble gas?

Ions are formed when elements gain or lose electrons.


In an ionic compound does one or more atoms lose electrons and one or more atoms gain?

In an ionic compound, one or more atoms lose electrons to become positively charged ions (cations), while one or more atoms gain electrons to become negatively charged ions (anions). These oppositely charged ions are held together by strong electrostatic forces to form the ionic compound.


What do ions gain or lose?

Electrons


Is ionic compound a solid?

An Ionic compound is any compound in which some of the atoms gain or lose electrons to form Ions, and it has no specific state (solid, liquid, gas). So, the short answer is no, not necessarily.


When atoms lose or gain electrons they from?

When atoms lose or gain electrons, they form ions. These are charged particles.


Do atoms lose protons but seldom lose or gain electrons?

Atoms typically do not lose protons because that would change the identity of the element. Instead, atoms can lose or gain electrons to form ions with a different charge. Protons are not generally lost by atoms in chemical reactions.


In forming a chemical compound does an atom of an element gain or lose electrons?

Electrons are both gained and lost in the formation of an ionic compound. The metal atom loses one or more electrons to the nonmetal with which it bonds. So the metal atom becomes a positively charged ion and the nonmetal atom becomes a negatively charged ion, and the ionic bond is formed by the electrostatic attraction between the oppositely charged ions, forming the ionic compound.


What does it mean to say a stable binary ionic compound?

A stable binary ionic compound is one that has a balanced ratio of positive and negative ions, resulting in a neutral overall charge. This balance ensures that the compound does not easily lose or gain additional ions, making it chemically stable.


Do acids lose or gain hydrogen ions?

Acids lose hydrogen ions when they donate them in a chemical reaction, making them stronger acids.


Do nonmetals gain or lose ions?

Yes. They can do both.


When nonmetals and metals react which atoms gain electron?

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.
