Does oxygen gain or lose electrons?
Oxygen has an electron arrangement of (2, 6) and needs to gain two electrons to fill the n=2 energy level and achieve an octet of electrons in the outermost shell.
How many electrons does oxygen gain?
Oxygen needs two electrons to fill its outermost electron shell. Hydrogen has one electron to play with.

Why does oxygen gain two electrons?
Oxygen is in group six in the periodic table so it has six electrons in its valence shell. This means that it needs to gain two electrons to obey the octet rule and have a full outer shell of electrons (eight). Because electrons have a charge of 1-, adding two electrons would make the charge of the oxide ion 2-.
What happens when oxygen loses an electron?
Oxidation is a combination of elements with oxygen. It’s also a reaction of losing electrons and gaining positive charge. The atoms that lost electrons are said to be oxidized. Atoms can be oxidized by nonmetals.
What is oxygen electron?
Oxygen is the eighth element with a total of 8 electrons. In writing the electron configuration for oxygen the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for O go in the 2s orbital. The remaining four electrons will go in the 2p orbital.
What is oxygen number of neutrons?
Consider oxygen, which has an atomic number (Z) of 8. This means that oxygen atoms have 8 protons. Most atoms of oxygen also have 8 neutrons.
Would magnesium lose or gain electrons?
Magnesium has a total of 12 electrons – 2 in the innermost shell, 8 in the second shell, and two electrons in its valence shell (third shell). Magnesium acquires a full octet by losing 2 electrons and emptying out its outermost shell.
Can oxygen have 10 electrons?
While the neutral oxygen atom has 8 total electrons, 2 are in the innermost (s) shell while the valence shell, which can hold 8 electrons, has only 6. Thus, oxygen tends to gain 2 electrons, for a total of 10 electrons.

Does oxygen lose or gain valence electrons?
2. Magnesium looses electrons in Ionic bonding because in order for it to be complete, it needs to transfer two valence electrons to another element. Oxygen gains electrons because it wants to be complete or be like the “Noble Gases”.
How many protons and electrons does oxygen have?
Now you can figure out how many electrons, protons and neutrons Oxygen has: Atomic number (which is always the smaller of the two numbers) is 8. Hence 8 protons. Because the atom is neutral, there are also 8 electrons.
Is oxygen positively or negatively charged?
The oxygen atom is slightly negatively charged, and the carbon and hydrogen atoms are slightly positively charged. The polar bonds of the hydroxyl group are responsible for the major reaction characteristics of alcohols and phenols.
Does oxygen have a negative 2 charge?
2 Answers. To expand, the oxide anion, O2− , does indeed have a charge of −2 . The oxygen atom , and the oxygen molecule are formally neutral.
Why does oxygen lose electron?
Oxygen is one of the more electronegative elements, and wants to attract electrons to itself. Oxidation is the addition of oxygen, and is also removal of electrons, as the added oxygen atom will attract electrons to itself, thereby making the original element lose electrons.
What is the gain of electrons?
The gain of electrons is called reduction. Because any loss of electrons by one substance must be accompanied by a gain in electrons by something else, oxidation and reduction always occur together. As such, electron-transfer reactions are also called oxidation-reduction reactions, or simply redox reactions.
Is gain of electrons reduction?
Oxidation is the loss of electrons, gain of oxygen or loss of hydrogen. Reduction is the gain of electrons, loss of oxygen or gain of hydrogen. These examples show how to explain oxidation and reduction.
Who discovered oxygen in 1772?
When Joseph Priestley discovered oxygen in 1774, he answered age-old questions of why and how things burn.

How many electrons do oxygen atoms need to gain in order to achieve a stable electron configuration?
For example, we know that Oxygen always forms 2- ions when it makes an ion. This would add 2 electrons to its normal configuration making the new configuration: O2– 1s22s22p6. With 10 electrons you should note that oxygen’s electron configuration is now exactly the same as Neon’s.
