All atoms have a neutral charge until they lose or gain electrons. Once they lose/gain electrons then they are considered ions.
Gaining electrons- If atoms gain electrons then they are getting negatively charged particles making them have a negative charge.
Losing electrons- If atoms lose electrons then they are losing a negative charge and they become a positively charged ion.
Oxygen- Oxygen will have a negative charge before a positive charge because it needs only two electrons to have a stable valence level. For example, Oxygen will take the electrons from two Hydrogen atoms and make H20.
All atoms have 0 charge, that is, they are neutral. If you meant an oxygen atom gains two electrons to become a ion of oxygen, then the charge would be 2-.
The charge will become more negitive. Protons are positive, electron are negitive. Nutrons do not have any charge.
Any atom that gains two electrons will have a charge of -2.
Oxygen has 6 outer shell valence electrons, and it "wants" eight. So it gains 2 electrons creating the charge of O-2
The oxygen atom is usually neutral (without a net charge). Sometimes the atom is ionized and then it can have a charge or -2, or sometimes of -1.
-2
oxygen
Beryllium is element 4, so the "neutral" atom would have 4 protons and 4 electrons. In order to have a "-2" charge, it would need 6 electrons.
Sulfur normally has 16 electrons, so....,S 2-===A 2 - charge on the anion.
Sodium Ions would be attracted to Oxygen Ions because in all elements there are layers of electrons, the first layer is always 2 electrons, but all the layers after that have to be 8 electons otherwise they arent stable, which is why elements have charges. It is all elements goal to be stable meaning having an outer layer with 8 electrons. So because Sodium (NA) has an ionic charge of +1 that means it has one to many electrons to be stable, so its goal is to lose one electron. Oxygen has an Ionic charge of -2 because it needs two more electorns to become stable. So Sodium is attracted to Oxygen because 2 sodium will bond with 1 oxygen thereore the sodium have one electron to give up and when they both (2NA) give theirs up there is 2 electrons left, when combining with oxygen (which needs two electrons to become stable) they bond and become a balanced compound. 2NaO
Ca must lose 2 electrons to have a complete 3n shell, which has 8 valence electrons. The ion would have a charge of 2+: Ca^2+.
Oxygen needs 8 electrons to have no charge.
An Oxygen atom would never contain 10 electrons on its own. It would have a maximum of 8 electrons at one time, unless the "oxygen atom" you are referring to is in fact an oxygen ION, in which case the charge would be -2. However, an oxygen ion can never be "by itself". It must be bonded with either itself as a diatomic or with another element as a compound.
It would have a negative charge. It would be a negative ion with a 2+ charge.Remember: when an atom gains electrons they become NEGATIVE.when an atom loses electrons they become POSITIVE.
Oxygen wants to gain 2 electrons, so its charge would be 2-, because electrons have a negative charge.
No. It would have 10.
12
when it forms an ion it would gain two electrons, becoming negatively charged (2-)
It must gain 2 electrons to become stable then it would have a charge of -2 and be iso-electronic with Neon.
Well the charge on the compound would be stable (0) when bonded, because the Calcium has given it's electrons to the Oxygen atom. But the charge on the calcium ion itself would be 2+
The charge would be negative, since electrons are negatively charged.
Nitrogen would have a neutral charge and eight valence electrons.
An element you have a +2 charge It is had lost electrons. It would have to lose the same number of electrons that its positive charge is. So it would have lost 2 electrons.
