When metals lose their valence electrons they form positive ions, or cations.
Metal atoms form metal objects, such as forks, nails, I beams, etc. They also tend to form ionic compounds when they combine with nonmetals. Salt is partially metallic and so is stone.
They become positive ions.

== == When metals react with other elements, the atoms of the metals give up their valence electrons.
Atoms gain lose or share valence electrons in a way that makes the atoms more stable
Because they either lose or gain valence electrons.
Cations form when atoms lose electrons, they gain a positive charge as a result.
• Metalloids: usually form covalent bonds with atoms of metals, nonmetals and other metalloids. They can easily take electrons from metals and lose electrons to nonmetals. • Metalloids: usually form covalent bonds with atoms of metals, nonmetals and other metalloids. They can easily take electrons from metals and lose electrons to nonmetals. They form because they want their valence shell to be full. Metals usually lose valence electrons because they want to stabilize their valence shell. Metalloids depends because they have different properties of metals and non metals.

Atoms with eight valence electrons usually do not gain or lose electrons. Atoms with one, two, or three valence electrons will lose electrons.

Because they either lose or gain valence electrons.
It is a matter of how full an atom's outer or valence shell of electrons is. For most atoms, the most stable setup is one with a full shell of 8 valence electrons, and an atom will gain or lose electrons to achieve this. For atoms with close to 8 valence electrons, such a chlorine (7 valence electrons, it is generally easier to gain electrons and thus become negatively charged. For atoms with few valence electrons, such as sodium (1 valence electron), it is easier to lose electrons and go down to the next lowest shell, which is already full.
A reaction in which the atoms in an element lose electrons and the valence of the element is correspondingly increased.
Cations form when atoms lose electrons, they gain a positive charge as a result.
An atom's charge changes when it gains or loses electrons. Atoms naturally tend to lose or gain electrons to level out at eight valence electrons (valence electrons are electrons in the outermost energy level), so the only atoms that keep their charge are ions with eight valence electrons or the Noble Gases, atoms on the far right of the periodic table that have eigth valence electrons and a nuetral charge.
Two types: Covalent, in which they share valence electrons to form molecules. Ionic, in which they give or lose valence electrons two each other.
