Is the loss of one or more electrons in a chemical reaction?
Oxidation occurs when an atom, molecule, or ion loses one or more electrons in a chemical reaction. When oxidation occurs, the oxidation state of the chemical species increases.
What is the charge of an atom if it loses two electrons?
As discussed in class, the elements in the first column of the periodic table (excluding hydrogen) always lose one electron to get a +1 charge. The elements in the second column lose two electrons to get a +2 charge.
What happens when an atom loses an electron?
An atom that gains or loses an electron becomes an ion. If it gains a negative electron, it becomes a negative ion. If it loses an electron it becomes a positive ion (see page 10 for more on ions).

What group of atoms is more likely to lose electrons?
Metal atoms lose electrons to nonmetal atoms because metals typically have relatively low ionization energies. Metals at the bottom of a group lose electrons more easily than those at the top. That is, ionization energies tend to decrease in going from the top to the bottom of a group.
Which atom will tend to lose electrons?
A lithium atom has 3 protons and 3 electrons. It can lose one of its electrons, making it an ion. It now has more positive protons than electrons so it has an overall positive charge. Therefore it is a positive ion. A fluorine atom will tend to gain, rather than lose, an electron.
What are atoms that have gained or lost electrons?
An ion is an atom (or group of atoms) that has lost one or more electrons, giving it a net positive charge (cation), or that has gained one or more electrons, giving it a net negative charge (anion).
What do you call atoms that gain or loose electrons?
When atoms lose or gain electrons, they become what are called ions. Loss of electrons leaves an atom with a net positive charge, and the atom is called a cation. Gain of electrons leaves an atom with a net negative charge, and the atom is called an anion.
