An atom does not easily lose or gain electrons if is has an equal number of protons and electrons. The charges inside the atom cancel each other, making it neutral.
the molecules are considered neutral so in order for it to gain or lose electrons it must first bond with another molecule.
Chlorine gain electrons.
gain 2 electrons
Sulfur will gain 2 electrons
An atoms protons cannot change.The number of neutrons can change (gain or lose) to form an isotope (ex. Hydrogen naturally has no neutrons. But it can gain neutrons to form Heavy Hydrogen, or in other words, a Hydrogen Isotope).An atom can gain or lose electrons to form an ion. Usually an atom will gain or lose electrons to fill its valence (outermost) shell. It takes just as much energy to gain an electron as it is to lose one, so an atom will always look to lose or gain the least amount of electrons possible. (ex. Oxygen has 6 valence electrons. It will look to gain 2 electrons, rather than lose 6).Protons: DO NOT CHANGENeutrons: Can change to form an isotopeElectrons: Can change to form an ion
The atom is neutral; the cations of Po are of course positive. Polonium lose electrons.
Chlorine gain electrons.
gain
The gain and/or lose of electrons.
Atoms do not always lose electrons. Electrons can be gained too. Atoms always try to have their outer most shell filled, and some atoms such as ones of potassium can easily lose an electron rather than gain an electron. So it would lose an electron to a different atom so that it would have a full outer shell and the other atom would also have a full outer shell.
easily gain electrons
It needs to lose, or gain, electrons.
gain 2 electrons
No. A metallic atom will typically lose electrons.
Sulfur will gain 2 electrons
Lithium loses electrons.
A Fluorine atom has an atomic number of 9. Draw out the electron shell diagram for Fluorine. Is a Fluorine atom more likely to gain, lose or share electrons to fill its valence shell?
Ionic bonding- the transfer of electrons from one atom to another. This results in ions, as the atoms which gain/lose electrons now have a charge.
