The "atomic number" of an element is the number of protons in its atoms. The number of neutrons may be different, creating "isotopes" of the element. Altering the number of protons in an atom changes it to a different element. Since oxygen atoms contain 8 protons, losing one would create an atom of NITROGEN, containing 7 protons. Isotopes are listed by the "mass number", which is the total number of protons and neutrons in an atom. An atom of oxygen would normally be oxygen-16, with 8 protons and 8 neutrons. Losing one proton from this atom would create NITROGEN-15, a stable isotope of nitrogen with 7 protons and 8 neutrons.

What happens in terms of electrons when lithium reacts with oxygen?
Oxygen is more electronegative than lithium, a metal. Oxygen has a tendency to gain two electrons so it will bond with two lithium atoms which have a tendency to donate one valence electron for bonding. Li2O
How many electrons are transferred in the ionic bond between Calcium and Oxygen?
Two electrons are transferred in the ionic bond between Calcium and Oxygen. Calcium (Ca) loses two electrons to form Ca2+ ions, while Oxygen (O) gains two electrons to form O2- ions, resulting in the transfer of two electrons in total.
In the reaction of sodium with oxygen what atom will be reduced?
Oxygen will be reduced in the reaction with sodium because it gains electrons to form the oxide ion (O2-).
What happens to the outer shell of a calcium atom when it reacts with an oxygen atom?
When a calcium atom reacts with an oxygen atom, the calcium atom loses two electrons from its outer shell and the oxygen atom gains those electrons. This forms a calcium ion with a 2+ charge and an oxygen ion with a 2- charge. These ions then bond together to form calcium oxide.
If 2 electrons where added to oxygen atom what would be the charge?
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.
What happens to beryllium electrons with oxygen?
When beryllium reacts with oxygen, it forms beryllium oxide. Beryllium loses its two valence electrons to oxygen, which gains these electrons to form an ionic bond in beryllium oxide.
How many electrons will each element gain in forming an ion Nitrogen oxygen sulfur bromine?
Nitrogen gains 3 electrons, oxygen gains 2 electrons, sulfur gains 2 electrons, and bromine gains 1 electron when forming ions.
What gains two electrons when they react?
Oxygen.
Oxygen gains 2 electrons to become what?
Oxygen gains 2 electrons to become an oxide ion (O2-).
Do oxygen gain or lose electrons?
Oxygen is an oxidizer, it will gain electrons in a reaction to complete it's valence shell.
Which element gains 2 electrons?
Oxygen gains 2 electrons to achieve a full valence shell with 8 electrons. This gives oxygen a stable electron configuration similar to the noble gas configuration.
Describe in terms of electrons what happens when an oxygen atom forms an oxygen ion state the charge on the oxygen ion formed?
Oxygen, O. Oxygen is in Group 6. It has six electrons in its outer shell. It gains two electrons from one or two other atoms in reactions, forming an oxide ion, O 2-
How many electrons does an oxygen anion have?
An oxygen anion has 10 electrons, because it gains two electrons to achieve a full valence shell of 8 electrons.
What is the electric charge of an oxygen atom that gains 2 electrons in an oxygen ion?
An oxygen atom has 6 protons and 6 electrons, giving it a neutral charge. When it gains 2 electrons to form an oxygen ion, it will have 8 electrons in total. Since it now has 2 more negatively charged electrons than positively charged protons, the oxygen ion will have a charge of -2.
How many electrons were gained or lost in oxygen?
In oxygen, each atom gains two electrons to achieve a stable electron configuration through forming two covalent bonds. This means that each oxygen atom gains two electrons to reach a full valence shell.
What happens to the neutrally charged object if it gains electrons?
If a neutrally charged object gains electrons, it becomes negatively charged. Electrons carry a negative charge, so adding more electrons to an object will result in an overall negative charge.
How many electrons are in an oxygen anion O2 and minus?
An oxygen anion with a charge of -2 has 10 electrons. Oxygen normally has 8 electrons, but an anion with a -2 charge gains two additional electrons.
