Neon is a member of Group XVIII, which are noble gases. Noble gases have all of their outer electron shell filled, so it takes a great deal of energy to pry one loose or to make it accept another one.
Because its electron shells are completely filled, neon has a valance of zero and is normally inert.
neon is stable, it doesn't lose or gain any electrons
The atomic number of neon is 10. So there are 10 protons and 10 electrons.
Neon atoms have already got the stable electronic configuration and shows very less reactivity.
lose electrons and become positive ions
A non-metal atom
Chlorine gain electrons.
An atom with incomplete octet tends to attain the noble gas configuration by the gain or loss of electrons. If an atom contains 2 electrons in its outer orbit, it would be more energy efficient for it to lose the two electrons and complete the octet, as opposed to gaining 6 electrons for the same.
Metals
Metals tend to lose electrons.
The kind of atom that likes to be oxidized.
lose electrons and become positive ions
A non-metal atom
Chlorine gain electrons.
An atom with incomplete octet tends to attain the noble gas configuration by the gain or loss of electrons. If an atom contains 2 electrons in its outer orbit, it would be more energy efficient for it to lose the two electrons and complete the octet, as opposed to gaining 6 electrons for the same.
Metals
An atom loses electrons through an ionic bond when it is a metal. This is because it will become stable more easily when it loses electrons than when it gains them.
Beryllium lose electrons (2).
The contact with an atom having a high affinity for electrons.
The most recent accurate answer would be Neon. At least that's what my memory ( and my periodic table of the elements) tells me. If I am not correct please let me know!
if an atom gains or loses electrons, it is no longer has an equal number of electrons and protons. Because the charges do not cancel completely, the atom has a net electric charge.
