When alkali metals become ions they loose a single electron from their outer shell and become electrostatically attracted to the ion they lost it too as the other ion should have an opposite charge, though not always equal. Like if you bonded sodium with a group 5 element you would need 3 alkali ions and a single group 5 ion. Brilliant.
Also worth mentioning, because alkali metals (group one) only have to loose one electron to gain a full outershell, they do so readily, making them very reactive.

Why does the pH of water change after a reaction with an alkali metal?
Yes, the pH increases because the alkali metal atoms replace some hydrogen ions in the water with alkali metal ions.
When a metal loses electrond it becomes?
Metal atoms become ions when they lose electrons.
What is the charge on an alkali metal ion?
the charge on all alkali metal ions is 1 +
What is the charge of all alkali metal ions?
Alkali metals are found in group 1 of the periodic table. They will form ions with a 1+ charge. If you meant alkaline earth, they are found in group 2, and will form ions with a 2+ charge.
Is ion a metal?
No, an ion is any atom or group atoms with a net positive or negative electric charge. Metals can form ions, but compounds contain metal ions are known as metal salts, not metals. In their pure "metallic" form metals exists as neutral atoms.

What are the colours of the alkali metal ions respectively?
They do not have color.

Why sodium carbonate being a salt acts as an alkali metal?
It is not an alkali metal, but it is alkaline. The carbonate ion is a weak base; it reacts with water in small amounts to form bicarbonate ions and hydroxide ions.
Where does copper collect during electrolysis?
The cathode, where the +ions in solution accept electrons and become neutral metal atoms.
What is the difference from a ionic bond and a covalent bond?
A covalent bond is formed when two or more non-metallic atoms share a pair of valence electrons.Non-metal atoms will want to share electrons in order to obtain a full valence energy level.Ionic bonds results when electrons are transferred from metal atoms to non-metal atomsRecall that metals are on the left side of the periodic table (alkali metals and alkaline earth metals) and non-metals are on the right side (oxygen's family and the halogens, for example)The metal atoms will lose valence electrons to become positive ions (cations) while the non-metal atoms will gain electrons to form negative ions (anions).
Do metal atoms decrease in size when they combines with nonmetal atom?
As metals have to become metal ions in order to chemically combined with nonmetals they have to lose their valance electrons. This process is associated with making the atoms smaller.
What types of atoms form positive ions?
atoms that belong to a metal element....because metals always loose electrons and gain a positive charge..!
How do sizes of atoms of alkali metals compared to their positive ions?
The atomic radius of cations is lower.
