No. It would have 10.
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.
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.
Oxygen needs 8 electrons to have no charge.
The oxygen atom in O2 would have a partial negative charge due to its higher electronegativity compared to hydrogen in HCl and fluorine in F2. Oxygen tends to attract electrons more strongly, resulting in a partial negative charge on the oxygen atom in the O2 molecule.
Oxygen wants to gain 2 electrons, so its charge would be 2-, because electrons have a negative charge.
An excess of electrons would produce a negative (-) charge since these particles are negative. If you imagine a scale with negative and positive weights, more negative weights would make the scales tip towards the negative end.
If an ion has more electrons than protons, it would have a negative charge. The charge of the ion would be equal to the excess of electrons over protons.
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.
The charge would be negative, since electrons are negatively charged.
Electrons are found outside the nucleus of the atom and they have negative charge.
No, Neon does have 10 electrons but it has no charge
Since protons have a positive charge and electrons have a negative charge, an atom with more protons than electrons would have a positive charge. Note that an atom with this kind of imbalance is known as an ion.
