Metals tend to lose electrons.
An atom with single electron in its outermost shell
The hydrogen atom has 1 electron.
All elements in the 7th family/group (2nd from the right) on the Periodic Table.
All right Cesium is an Alkali Metal so it belongs to the first column of the periodic table. Every element in that column has a charge of 1+ as a cation. So to answer your question, a single Cesium atom loses 1 electron when it becomes a cation. The cation looks like this: Cs = 55 Electrons Cs^+ = 54 Electrons As you can see it only loses one :)
Chlorine (Cl) is most likely to form a compound with magnesium in a one-to-one ratio to create magnesium chloride, which is a common ionic compound. Magnesium tends to lose two electrons to achieve a full outer shell, while chlorine tends to gain one electron.

The hydrogen atom has 1 electron.
lose only one electron
True. Sodium typically has 11 protons and 11 electrons, but it tends to lose one electron to achieve a more stable electron configuration in its outer shell. This loss of an electron forms a positively charged sodium ion.
This atom lose an electron.
All elements in the 7th family/group (2nd from the right) on the Periodic Table.
An atom of potassium is most likely to become a cation. Potassium tends to lose one electron to achieve a stable electron configuration, forming a positively charged ion.
A chlorine atom would gain one electron to become an ion because it tends to achieve a stable electron configuration by having a full outer shell of electrons.
Atoms will form an ionic bond when one atom donates an electron to another atom. Typically, this occurs between a metal atom (which tends to lose electrons to form positive ions) and a non-metal atom (which tends to gain electrons to form negative ions).
lose one electron to form a potassium ion with a +1 charge.
The Alkali Metals loose one electron in order to achieve a nobel gas configuration.
lose an electron, forms Na+, sodium with a charge of plus one.
