A neutral oxygen atom has 8 electrons. When oxygen becomes an ion, it can gain 2 electrons to become O2-, losing the neutral 8 electrons to become a total of 10 electrons in the ion.
An atom that gains or loses electrons is called an ion. When an atom loses electrons, it becomes positively charged and is called a cation. When an atom gains electrons, it becomes negatively charged and is called an anion.
O2 has 16 electrons. Each oxygen atom has 8 electrons, and since O2 is a molecule made of two oxygen atoms, the total number of electrons is 16.
False. If an atom gains or loses electrons, the result is called an ion, not a molecule.
An atom that loses electrons becomes a positively charged ion called a cation. An atom that gains electrons becomes a negatively charged ion called an anion.
When an atom loses electrons, it becomes a positively charged ion called a cation. When an atom gains electrons, it becomes a negatively charged ion called an anion.
The negatively charged particles that move around the atom's nucleus is called electrons.
An atom that gains or loses electrons is called an ion. When an atom loses electrons, it becomes positively charged and is called a cation. When an atom gains electrons, it becomes negatively charged and is called an anion.
O2 has 16 electrons. Each oxygen atom has 8 electrons, and since O2 is a molecule made of two oxygen atoms, the total number of electrons is 16.
A charged atom is an ion. An atom that has lost one or more electrons becomes a positively charged ion called a cation. An atom that has gained one or more electrons becomes a negatively charged ion called an anion.
Electrons
False. If an atom gains or loses electrons, the result is called an ion, not a molecule.
Oxygen's atomic number is 8. Thus it has 8 positively charged protons per atom. In order for oxygen to be neutral, it must also have 8 negatively charged electrons in each atom.
A negatively charged atom is called an anion, which is an atom that has more electrons than protons.
An atom that loses electrons becomes a positively charged ion called a cation. An atom that gains electrons becomes a negatively charged ion called an anion.
When an atom loses electrons, it becomes a positively charged ion called a cation. When an atom gains electrons, it becomes a negatively charged ion called an anion.
Electrons are negatively charged (around the nucleus) and protons are positively charged (inside the nucleus)
If 2 electrons are added to an oxygen atom, it will form an oxygen ion with a charge of -2. The oxygen atom gains a negative charge because it now has two more negatively charged electrons than positively charged protons.
