Like other metals cesium loses electrons.
Cesium and sulfur are unlikely to form a bond since cesium is a highly reactive metal that tends to lose an electron to obtain a stable electron configuration, while sulfur is a non-metal that tends to gain electrons. This difference in reactivity makes it unlikely for them to form a stable bond together.
Cesium has a low electronegativity because it is a highly reactive alkali metal. Alkali metals typically have low electronegativities due to their tendency to lose electrons easily.
Krypton can gain a maximum of 2 electrons to achieve a stable octet configuration, forming the Kryptonide anion. It does not typically lose electrons.
Cs3P. Cesium has one valence electron and Phosphorus has 5. Each of these elements wants to get to a perfect set of 8 valence electrons.5 plus 3 is eight, so you will need 3 Cesium and 1 phosphorus.
Polonium will neither gain nor lose electron. it will prefer to form covalent compounds by sharing of electrons.
Cesium tends to lose electrons rather than gain them. As an alkali metal, cesium typically forms a +1 cation by losing its single valence electron to achieve a stable electron configuration.
Lose
When atoms lose or gain electrons, they form ions. These are charged particles.
Se will gain electrons
Lose electrons is oxidation. To gain electrons is reduction.
Silicon (Si) can gain or lose 4 electrons. It can either gain 4 electrons to have a stable octet configuration or lose 4 electrons to achieve a stable configuration.
If you mean Metals... No, they do not gain electrons, they actually lose electrons because it is a lot easy for them to lose them so they can gain stability much faster.
it loses electrons
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.
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 :)
Selenium may lose 2, 4 or 6 electrons and may gain 2 electrons.
