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.
A nitrogen ion with 10 electrons would have a charge of +3, as nitrogen normally has 7 electrons and a neutral nitrogen ion would have 7 electrons. By having 10 electrons, it has lost 3 electrons, resulting in a +3 charge.
The charge on a magnesium ion with 10 electrons (Mg2+) is +2.
I'm assuming you mean when they're bonded to each other - oxygen is more electronegative, so it will have a partial negative charge, and hydrogen will have a partial positive charge.
Magnesium has 12 protons, so if there are only 10 electrons, then it will have a +2 charge.
The charge on a particle of Sulfur-33 with 18 electrons would be -15, as the number of protons in sulfur-33 is 16. Since electrons have a negative charge of -1 each, 16 protons (positive charge) neutralized by 16 electrons would result in a net charge of -15.
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.
No. It would have 10.
The oxygen atom would have a charge of -2 after gaining two electrons to become an oxygen ion.
12
Oxygen wants to gain 2 electrons, so its charge would be 2-, because electrons have a negative charge.
An oxygen ion typically forms a 2- charge by gaining two electrons to achieve a more stable electron configuration.
when it forms an ion it would gain two electrons, becoming negatively charged (2-)
Basically, an ion is when the charge of an element is not what it would normally be. So if you took oxygen, which is naturally a -2 charge, and it lost an electron, it would become an oxygen ion with a charge of -1.
To convert a neutral oxygen atom to an anion carrying a charge of 2-, you need to gain two electrons. Oxygen has six electrons in its neutral state, so gaining two more electrons would give it a total of eight electrons, achieving a full outer electron shell and forming the oxide ion (O^2-).
Electrons are subatomic particles that always have a charge of -1 elementary charge. If they were to have no charge, they would not be electrons.
