That depends entirely on sign of the charge. If the object gains a positive charge, then that means the object as lost electrons, since electrons are negatively charge. If the charge is negative, then the object has gained electrons. It is also possible that the charge was created by a movement in protons, which are positively charged, in which case the object may not have lost or gained electrons.
An atom will become Negative if it gains an electron and it will be an Anion.If it loses an electron it will be Positive and it will be a CationLearn & Enjoy
The resulting oxygen ion has a charge of -2.
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.
Negative, when the ion gains an electron. When an ion loses an electron it becomes positive.
The oxygen atom would have a charge of -2 after gaining two electrons to become an oxygen ion.
When an object gains electrons, it becomes negatively charged. When it loses electrons, it becomes positively charged. This change in charge affects the object's interactions with other charged objects.
An object becomes electrically charged when it gains or loses electrons. Gaining electrons gives the object a negative charge, while losing electrons gives it a positive charge. This imbalance of electrons creates an electric charge on the object.
It's safe to say if an object gains or loses electrons its electric charge has changed. If it was overall electrically neutral before it lost electrons, it would then have a positive charge; if it acquired electrons from initially being neutral, it would have a negative charge. At the atomic level this is called ionization.
Electrons can move from object to object. Electrons have a negative charge. So if an object is determined to have a positive charge, then some of the electrons have moved from the object to somewhere else. Something with a neutral charge has the same number of electrons [-] and protons [+]. If electrons [-] leave, then there will be more protons, and a net positive charge. If an object gains electrons, then the object has a net negative charge.
electric charge
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.
Electric charge is created when electrons are transferred between objects. This transfer of electrons can occur through friction, contact, or induction. When an object gains or loses electrons, it becomes positively or negatively charged, respectively.
Objects become charged when they gain or lose electrons. When an object gains electrons, it becomes negatively charged, and when it loses electrons, it becomes positively charged. This charge imbalance creates an electric field around the object.
An object gains a negative charge by gaining an excess of electrons. When an object either gains electrons from another object or loses protons, it can become negatively charged.
when an object gains or loses electrons
If you mean an atom, if it gains electrons it becomes more negative, so a negative charge. If you really mean an ion, it depends on the charge of the ion.
Electrons have a positive charge and protons have a negative charge. An atom's nucleus is 99.95% of its weight. When an object gains more electrons, it gains a negative charge that over comes the positive charge. This only happens when there are more electrons than protons.
