Nonmetals
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 want to have a full outer energy level of electrons, typically either 2 or 8 electrons, to become stable. This is known as the octet rule, in which atoms tend to gain, lose, or share electrons to achieve a stable electron configuration like the noble gases.
Potassium will lose electrons when reacting with bromine. Potassium is a metal and tends to lose electrons to achieve a stable electron configuration, while bromine is a nonmetal that tends to gain electrons to achieve a stable electron configuration.
Aluminium lends it's eletrons, it does not borrow it.
For potassium to become stable, it must have a full outer electron shell, typically with eight electrons (like a noble gas). This can be achieved by losing one electron to become a positively charged ion, as potassium tends to do in chemical reactions.
Boron becomes positive when it loses electrons. Boron has three valence electrons and tends to lose these electrons to achieve a stable electron configuration similar to a noble gas. When boron loses its three valence electrons, it forms a B3+ ion, which has a positive charge.
Tin (Sn) is a reducing agent because it tends to lose electrons to become more stable by transitioning to its +2 oxidation state. On the other hand, lead (Pb) is not a strong reducing agent because it tends to form more stable compounds in its +2 oxidation state rather than lose electrons easily.
Fluorine gains electrons to achieve a stable electron configuration. It has seven valence electrons and tends to gain one more electron to complete its outer shell and attain a full octet.
Yes, bromine tends to react by gaining electrons to achieve a stable electron configuration. It is a halogen and has seven valence electrons, so it typically gains one electron to complete its octet and attain a stable electronic configuration.
the atomic no of oxygen is 8 to reach the nearest noble gas electronic configuration it excepts 2 electrons and becomes isoelectronic to Neon.
Calcium is a lender of electrons because it tends to lose two electrons to achieve a stable electron configuration. It forms ionic bonds by giving away these electrons to elements that need to gain electrons to achieve stability.
The oxidation number of calcium is +2, as it tends to lose two electrons to achieve a stable electron configuration. The oxidation number of chloride is -1, as it tends to gain one electron to achieve a stable electron configuration.
