Bromine will gain one electron to become Br-
Sulfur can both gain and lose electrons when forming ions. It can gain two electrons to form a sulfide ion (S2-) or lose two electrons to form a sulfide ion (S2+).
Bromine (Br) has 35 electrons, while Krypton (Kr) has 36 electrons. To have the same electron configuration as Krypton, Bromine would need to lose one electron.
Potassium will lose 1 electron to form a 1+ ion.
Yes, cobalt can form an ionic bond with bromine. Cobalt can lose electrons to form a cation (Co2+) while bromine can gain electrons to form an anion (Br-), resulting in the formation of an ionic compound.
Beryllium will lose 2 electrons when forming an ion because it has 4 valence electrons and tends to reach a stable electron configuration by losing electrons to achieve a full outer shell.
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.
Some atoms lose electrons, some gain electrons, and some share electrons depending on what elements are involved and what compound is forming.

Bromine's atomic number is 35, so it has 7 valence electrons. To achieve 8 valence electrons and a full outer shell, bromine needs to gain one electron.
Boron can lose 3 electrons from its valence shell that is 2 in 2s & 1 in 2p sub-shell, wheras it cannot gain electron b'coz of its electropositive nature & it has less electron affinity.
Sulfur can both gain and lose electrons when forming ions. It can gain two electrons to form a sulfide ion (S2-) or lose two electrons to form a sulfide ion (S2+).
Selenium may lose 2, 4 or 6 electrons and may gain 2 electrons.
It'll have to gain one to have a stable octet.
Bromine (Br) has 35 electrons, while Krypton (Kr) has 36 electrons. To have the same electron configuration as Krypton, Bromine would need to lose one electron.
Beryllium would tend to lose its two electrons when forming a bond because it is easier to lose its two valence electrons rather than gain an additional five in order to obtain a full outer shell.
Bromine, being in the second column from the rigth of the periodic table has a high electronegativity so when it forms compounds it tends to gain electrons, in other words, it is a nonmetal. While metals, which have low electronegativities tend to lose electrons
Bromine gains one electron to achieve a full outer electron shell. It tends to form an anion with a charge of -1.
