Oxygen is an oxidizer, it will gain electrons in a reaction to complete it's valence shell.
Oxygen atoms gain two electrons during ionic bonding, and become ions with a 2- charge.
oxygen gains electrons.
Oxygen gains electrons to form an anion.
Oxygen gains electrons to form an anion.
Oxygen gain electrons.
It needs to gain 3 electrons than to lose 5 electrons. So phosphorus has to gain 3 electrons.
Iron reacts with oxygen to form Fe2O3 also known as rust. Oxygen requires two electrons to fill it's valence shell so iron loses electrons.
gain 2
It is going to lose electrons
Selenium may lose 2, 4 or 6 electrons and may gain 2 electrons.
Oxygen will gain two electrons to achieve a full outer shell.
when it forms an ion it would gain two electrons, becoming negatively charged (2-)
Magnesium has a charge of 2+ and oxygen 2- Magnesium will lose the two "extra electrons" in its valence shell when creating an ionic bond with oxygen. The oxygen will gain these two electrons.
It can both gain and lose electrons depending on the different elements. With hydrogen, it gains electrons to produce hydrogen sulphide and it will lose electrons with oxygen to produce sulphur oxides. Generally it will tend to gain electrons as it is in group 16 of the elements and so is quite negatively electrovalent but against a more negatively electrovalent elements it can be forced to lose electrons unwillingly as in the case of oxygen. Even though oxygen is also in group 16, sulphur is an order below oxygen and therefore less negatively electrovalent that oxygen.
No. Atoms can gain and lose electrons but seldom gain or lose protons.
se and sometimes gain electrons. Atoms with eight valence electrons do not easily lose electrons
Covalent bonds do not gain or lose electrons, but rather share electrons.
It needs to gain 3 electrons than to lose 5 electrons. So phosphorus has to gain 3 electrons.
that would depend on what specifically the were reacting with on each instance.
Oxygen molecules tend to prefer covalent bonding when forming compounds. This means that they will share electrons more readily. However, when forming an ionic compound, they will usually gain electrons rather than losing them.
Lose
Corrected: All atoms have a neutral charge until they lose or gain electrons. Once they lose/gain electrons then they are considered ions with respectively positive (on loosing) or negative charge (on gaining electrons, as oxygen tends to do).NO: 2-. It's the same as minus 2, but is written as 2- for conventions.
