The loss of one or more electrons forms a cation; some atoms gain one our more electrons in becoming anions. Both anions and cations are ions. Anions have a negative valence (charge), cations have a positive valence. Cations and anions attract one another to form compounds, substances consisting of two or more kinds of atoms. These compounds, dissolved in water, a polarized solvent, become solute and revert to ions. In such solution, the cations, having positive charges, are attracted to the negative poles of water molecules, and this arrangement enhances the solvency of the compound in water. Similarly, the anions, having negative charges, are attracted to the positive poles of the water molecules. In this way, a solution of the compound in water is formed.

What happens when an atom loses an electron form its outermost shell?
It becomes a positive ion, and also connects with the atom that stoles its electron.
What happens when atom looses electron?
If an atom loosed electrons then it becomes an ion. The electrical charge in the atom becomes a positive ion.
What happens when a chlorine atom and a hydrogen Adam exchange electron?
When a chlorine atom and a hydrogen atom exchange electrons, the chlorine atom gains an electron to form a chloride ion (Cl-), while the hydrogen atom loses an electron to form a hydrogen ion (H+). This exchange is a type of ionic bond formation where the atoms become charged ions.
What happens to an atom if it gains an electron will it be a negative ion or positive ion?
It will be a negative ion, or in other words, a anion.
What happens when a atom forms an ion?
The atom had either lost or gained one or more electrons forming and ion. Thus the ion has an overall electric charge.
What does a nonmetal atom need to do to form an ion?
A non metal needs to GAIN electrons to form an ion
What type of ion will sulfure form?
A sulfur atom will gain two electrons to form a 2- sulfide ion.
What happens when an atom has an extra electron?
It becomes a negatively charged ion.
What happens when Na turns into an ion?
Sodium atom lose an electron.
Wta happens whenan atom forms an ion?
When an atom forms an ion, it gains or loses electrons, resulting in a positive or negative charge. A positively charged ion is called a cation, and a negatively charged ion is called an anion. This change in the number of electrons affects the atom's chemical properties and reactivity.
How does an ion with a charge of 2 form?
For a neutral atom to become an ion with a 2 plus charge it must LOSE TWO ELECTRONS.
Is magnesium an ion or an atom?
Magnesium is an atom; but this atom can be transformed in an electrically charged atom - called cation, Mg2+.
