It needs 2 electrons for this. Oxygen makes -2 ion by gaining 2 electrons. It is the most stable ion that oxygen makes.
Oxygen wants to gain 2 electrons, so its charge would be 2-, because electrons have a negative charge.
Oxide is the ion form of oxygen. It forms when an oxygen atom gains an extra two electrons. So an oxide ion would become an oxygen atom by losing two electrons.
For a neutral atom to become an ion with a 2 plus charge it must LOSE TWO ELECTRONS.
No, Oxygen is an atom, and as such is composed of protons, neutrons and electrons. There are no molecules in oxygen, but a single oxygen atom becomes a molecule when it is combined with another oxygen atom to form O2.
An atom that has eight protons, seven neutrons and nine electrons is an oxygen atom because of the eight protons, seven neutrons makes it a particular isotope of oxygen, and with nine electrons means that it is an ion with a charge of minus one, this is unusual because oxygen tends to form ions with minus two not minus one
Oxygen wants to gain 2 electrons, so its charge would be 2-, because electrons have a negative charge.
Gaining 2 electrons gives the O atom the stable octet of electrons.
A lone, neutral oxygen atom has 6 electrons in its outer shell, but this is not very stable, so oxygen will tend to gain 2 more electrons in order to get a full, stable shell of 8 electrons.

There are eight electrons in the neutral form of the atom with the atomic number eight (oxygen or O). --- Answer 2: 8. The atomic number represents the number of protons (positive charge) in an atom. For the atom to have a neutral charge, there must be 8 negative charges in the shells around the nucleus of the atom.

It is the number of unpaired electrons in their valence shells. Oxygen has two unpaired valence electrons and carbon has four unpaired valence electrons.
Protons have a POSITIVE charge Neutrons don't have a charge, hence the name NEUTRON Electrons have a NEGATIVE charge Protons and Neutrons form the nucleus of the atom and Electrons spin around the nucleus
No, oxygen has 8 electrons in general (in neutral form) but only has 6 valence electrons.
Mg or magnesium has 2 electrons in its outer shell. O or oxygen is 2 electrons short of a full shell. The oxygen takes up the magnesium's spare electrons and gets a full outer shell and a charge of 2- (cos of the extra electrons). The magnesium gets a full outer shell cos it lost the spare 2 and gets a charge of 2+ (cos it lost 2 electrons that were balancing out the protons in the nucleus).So, one atom completely donates electrons to another atom. That's ionic bonding.
